NAME

       exiv2 - Image metadata manipulation tool

SYNOPSIS

       exiv2 [options] [action] file ...

DESCRIPTION

       exiv2  is  a program to read and write Exif, IPTC, XMP metadata and image comments and can
       read many vendor makernote tags. The program optionally converts between  Exif  tags,  XMP
       properties  and  IPTC datasets as recommended by the Exif Standard, the IPTC Standard, the
       XMP specification and Metadata Working Group guidelines.
       The following image formats are supported:

       Type      Exif         IPTC         XMP          Image Comments          ICC Profile

       • Support for GIF, TGA and BMP images is minimal: the image format is recognized,  a  MIME
         type assigned to it and the height and width of the image are determined.

       • Reading  other  TIFF-like RAW image formats, which are not listed in the table, may also
         work.

       • Support for BMFF file types such as CR3, HEIF, HEIC,  AVIF,  and  JPEG  XL  is  a  build
         option. To check if this is enabled, use:

           $ exiv2 --version --verbose | grep bmff
           enable_bmff=1

       • Naked codestream JPEG XL files do not contain Exif, IPTC, or XMP metadata.

ACTIONS

       The  action  argument is only required if it is not clear from the options which action is
       implied.

       pr | print
              Print image metadata. This is the default action, i.e., the command exiv2 image.jpg
              will print a summary of the image Exif metadata.

       ex | extract
              Extract  metadata  to  *.exv,  XMP  sidecar  (*.xmp)  and  thumbnail  image  files.
              Modification commands can be applied on-the-fly.

       in | insert
              Insert metadata from corresponding *.exv, XMP sidecar (*.xmp) and thumbnail  files.
              Use  option  -S  .suf  to  change the suffix of the input files. Since files of any
              supported format can be used as input files, this command can be used to  copy  the
              metadata  between  files of different formats. Modification commands can be applied
              on-the-fly.

       rm | delete
              Delete image metadata from the files.

       ad | adjust
              Adjust Exif timestamps by the given time. Requires at least one of the  options  -a
              time, -Y yrs, -O mon or -D day.

       mo | modify
              Apply  commands  to  modify  (add,  set, delete) the Exif, IPTC and XMP metadata of
              image files. Requires option -c, -m or -M.

       mv | rename
              Rename files and/or set file timestamps according to  the  Exif  create  timestamp.
              Uses   the   value   of   tag   Exif.Photo.DateTimeOriginal  or,  if  not  present,
              Exif.Image.DateTime to determine the timestamp. The filename format can be set with
              -r  fmt,  timestamp  options  are -t and -T. When no rename format is provided, the
              default is ´%Y%m%d_%H%M%S´ using definitions from strftime(3).

       fi | fixiso
              Copy the ISO setting from one of the proprietary Nikon or Canon makernote ISO  tags
              to  the  regular  Exif  ISO  tag, Exif.Photo.ISOSpeedRatings. Does not overwrite an
              existing standard Exif ISO tag.

       fc | fixcom
              Fix the character encoding of Exif Unicode  user  comments.   Decodes  the  comment
              using  the  auto-detected  or  specified  character  encoding and writes it back in
              UCS-2. Use option -n to specify the current encoding of the comment if necessary.

OPTIONS

       -h     Display help and exit.

       -V     Show the program version and exit.
              When -V is combined with -v (Verbose version),  build  information  is  printed  to
              standard  output  along with a list of shared libraries which have been loaded into
              memory. Verbose version is supported on Windows (MSVC, Cygwin  and  MinGW  builds),
              macOS and Linux and is provided for test and debugging.

       -v     Be verbose during the program run.

       -q     Silence  warnings  and error messages from the Exiv2 library during the program run
              (quiet). Note that options -v and -q can be used at the same time.

       -Q lvl Set the log-level to 'd'(ebug), 'i'(nfo), 'w'(arning), 'e'(rror) or  'm'(ute).  The
              default  log-level is 'w'. -Qm is equivalent to -q. All log messages are written to
              standard error.

       -u     Show unknown tags (default is to suppress tags which don't have a name).

       -g key Only keys which match the given key (grep).
              Multiple -g options can be used to filter info to less keys. Example: exiv2  -v  -V
              -g  webready -g time.  The default exiv2 command prints a "summary report" which is
              quite short.  When you use -g without a -pmod option, you  do  not  get  a  summary
              report and in effect you get -g pattern -pa image ...

              $ bin/exiv2 -g Date http://clanmills.com/Stonehenge.jpg
              Exif.Image.DateTime                 Ascii    20  2015:07:16 20:25:28
              Exif.Photo.DateTimeOriginal         Ascii    20  2015:07:16 15:38:54

              You may use -pmod filters to further filter output.  For example:
              $ bin/exiv2 -px -g Date http://clanmills.com/Stonehenge.jpg
              Xmp.xmp.ModifyDate                           XmpText    25  2015-07-16T20:25:28+01:00

              The option -g (--grep) applies to keys and not values.
              The key may finish with the optional modifier /i to indicate case insensitive.

       -K key Only report data for given key.
              Multiple -K options can be used to report more than a single key.
              $ exiv2 -K Exif.Photo.DateTimeDigitized -K Exif.Photo.DateTimeOriginal -pt R.jpg
              Exif.Photo.DateTimeOriginal   Ascii    20  2011:09:18 16:25:48
              Exif.Photo.DateTimeDigitized  Ascii    20  2011:09:18 16:25:48

       -n enc Charset  to  use  to decode Exif Unicode user comments. enc is a name understood by
              iconv_open(3), e.g., 'UTF-8'.

       -k     Preserve file timestamps when updating files (keep). Can be used with  all  options
              which update files. The flag is ignored by read-only options.

       -t     Set  the  file  timestamp  according  to  the  Exif create timestamp in addition to
              renaming the file (overrides -k). This  option  is  only  used  with  the  'rename'
              action.  See Exif DateTime below for additional information.

       -T     Only  set  the file timestamp according to the Exif create timestamp, do not rename
              the file (overrides -k). This option is only used with the 'rename'  action.  Note:
              On  Windows you may have to set the TZ environment variable for this option to work
              correctly.  See Exif DateTime below for additional information.

       -f,-F  These options are used by the commands 'rename' and 'extract' to determine the file
              overwrite  policy.  These options are usually combined with -v/--verbose to provide
              additional status output.

              The options --force and --Force apply  to  the  'rename'  command.   The  'extract'
              command treats --force and --Force as permission to overwrite.

              The default behaviour is to prompt the user.
              -f = Do not prompt before overwriting existing files.
              -F  =  Do not prompt before renaming files. Appends '_1' ('_2', ...) to the name of
              the new file.  For example:

              $ curl --silent -O http://clanmills.com/Stonehenge.jpg
              $ exiv2 --verbose --Force rename Stonehenge.jpg
              File 1/1: Stonehenge.jpg
              Renaming file to ./20150716_153854.jpg
              $ curl --silent -O http://clanmills.com/Stonehenge.jpg
              $ exiv2 --verbose --Force rename Stonehenge.jpg
              File 1/1: Stonehenge.jpg
              Renaming file to ./20150716_153854_1.jpg

              The 'rename' command will only overwrite files when the  option  --force  is  used.
              The option --Force is provided to avoid unintentional loss of valuable image files.

              The  'extract' command will overwrite files when either --force or --Force is used.
              Overwriting extracted files will not cause the loss of image files.

       -r fmt Filename format for  the  'rename'  action.  The  format  string  uses  strftime(3)
              definitions and supports the following keywords:

              :basename:     original filename without extension
              :dirname:      name of the directory holding the original file
              :parentname:   name of parent directory

              Note that the colons are part of the keyword.

       -a time
              Time  adjustment  in  the format [-]HH[:MM[:SS]]. This option is only used with the
              'adjust' action. Examples: 1 adds one hour, 1:01 adds  one  hour  and  one  minute,
              -0:00:30 subtracts 30 seconds.  See Exif DateTime below for additional information.

       -Y yrs Time adjustment by a positive or negative number of years, for the 'adjust' action.

       -O mon Time  adjustment  by  a  positive  or  negative  number of months, for the 'adjust'
              action.

       -D day Time adjustment by a positive or negative number of days, for the 'adjust' action.

       -p mode
              Print mode for the 'print' action. Possible modes are:

              s : print a summary of the Exif metadata (the default)
              a : print Exif, IPTC and XMP metadata (shortcut for -Pkyct)

       -P flgs
              Print flags for fine control of the tag list ('print' action).  Allows  control  of
              the  type  of metadata as well as data columns included in the print output.  Valid
              flags are:

              E : include Exif tags in the list
              I : IPTC datasets
              X : XMP properties
              x : print a column with the tag number

              V : plain data value AND the word 'set ' (for use with exiv2 -m-)
              t : interpreted (translated) human readable data
              h : hexdump of the data

       -d tgt Delete target(s) for the 'delete' action. Possible targets are:

              a : all supported metadata (the default)

              e : Exif section
              t : Exif thumbnail only
              i : IPTC data
              x : XMP packet
              c : JPEG comment
              C : ICC Profile
              I : All IPTC data

       -i tgt Insert target(s) for the 'insert' action. Possible targets are the  same  as  those
              for the -d option, plus an optional modifier:

              X  :  Insert  metadata  from  an  XMP sidecar file <file>.xmp. The remaining insert
              targets determine what metadata to insert from the sidecar file. Possible are Exif,
              IPTC and XMP and the default is all of these. Note that the inserted XMP properties
              include those converted to Exif and IPTC.

              XX: Insert "raw" XMP metadata from a sidecar (see option -pX)

              - : Read from stdin.  This option is intended for "filter" operations such as:
              $ exiv2 -e{tgt}- filename | xmllint .... | exiv2 -i{tgt}- filename

              Only JPEG thumbnails can be inserted (not  TIFF  thumbnails),  and  must  be  named
              file-thumb.jpg.

       -e tgt Extract  target(s) for the 'extract' action. Possible targets are the same as those
              for the -d option, plus a target to  extract  preview  images  and  a  modifier  to
              generate an XMP sidecar file:
              p[<n>[,<m>  ...]]  :  Extract  preview images. The optional comma separated list of
              preview image numbers is used to determine which preview  images  to  extract.  The
              available  preview  images  and their numbers are displayed with the 'print' option
              -pp.

              C : Extract embedded ICC profile to <file>.icc

              X : Extract metadata to an XMP  sidecar  file  <file>.xmp.  The  remaining  extract
              targets  determine what metadata to extract to the sidecar file. Possible are Exif,
              IPTC and XMP and the default is all of these.

              XX: Extract "raw" XMP metadata to a sidecar (see -pX)
              You may not use modify commands with the -eXX option and only XMP is written to the
              sidecar.

              - Output to stdout (see -i tgt for an example of this feature)

       -c txt JPEG  comment string to set in the image ('modify' action). This option can also be
              used with the 'extract' and 'insert' actions to modify metadata on-the-fly.

       -m file
              Command file for the 'modify' action.  This  option  can  also  be  used  with  the
              'extract'  and  'insert'  actions  to  modify  metadata on-the-fly.  -m- represents
              standard-input.

       -M cmd Command line for the 'modify' action.  This  option  can  also  be  used  with  the
              'extract'  and  'insert' actions to modify metadata on-the-fly.  The format for the
              commands is the same as that of the lines of a command file.

       -l dir Location (directory) for files to be inserted or extracted.

       -S .suf
              Use suffix .suf for source files in 'insert' action.

COMMANDS

       Commands for the 'modify' action can be read from a command file, e.g.,

       $ exiv2 -m cmd.txt image.jpg

       or given on the command line, as in

       $ exiv2 -M"add Iptc.Application2.Credit String Mr. Smith" image.jpg

       Note the quotes. Multiple -m and -M options  can  be  combined,  and  a  non-standard  XMP
       namespace registered.

       $ exiv2 -M"reg myprefix http://ns.myprefix.me/" -M"add Xmp.myprefix.Whom Mr. Smith" -M"set Exif.Image.Artist Mr. Smith" image.jpg

       When  writing  Exif,  IPTC  and  XMP  metadata,  exiv2  enforces  only  a correct metadata
       structure. It is possible to write  tags  with  types  and  values  different  from  those
       specified  in  the standards, duplicate Exif tags, undefined tags, or incomplete metadata.
       While exiv2 is able to read all metadata that  it  can  write,  other  programs  may  have
       difficulties with images that contain non standard-conforming metadata.

   Command format
       The format of a command is

       set | add | del key [[type] value]

       set    Set the value of an existing tag with a matching key or add the tag.

       add    Add  a  tag  (unless  key  is  a non-repeatable IPTC key; nothing prevents you from
              adding duplicate Exif tags).

       del    Delete all occurrences of a tag (requires only a key).

       key    Exiv2 Exif, IPTC or XMP key.

       type   Exif keys: Byte | Ascii | Short | Long | Rational | Undefined | SShort  |  SLong  |
              SRational | Comment
              IPTC keys: String | Date | Time | Short | Undefined
              XMP keys:  XmpAlt | XmpBag | XmpSeq | LangAlt

              A default type is used if none is explicitly given. The default is determined based
              on key.

       value  The remaining text on the line is the value.  It  can  optionally  be  enclosed  in
              single quotes ('value') or double quotes ("value").

              The value is optional. Not providing any value is equivalent to an empty value ("")
              and is mainly useful to create an XMP array property, e.g., a bag.

              The format of Exif Comment values include an optional charset specification at  the
              beginning.     Comments    are    used    by   the   tags   Exif.Photo.UserComment,
              Exif.GPSInfo.GPSProcessingMethod and Exif.GPSInfo.GPSAreaInformation.  Comments are
              stored  as  Undefined tags with an 8 byte encoding definition follow by the encoded
              data. The charset is specified as follows:

              [charset=Ascii|Jis|Unicode|Undefined] comment
              charset=Undefined is the default

              $ exiv2 -M'set Exif.Photo.UserComment charset=Ascii My photo' x.jpg
              $ exiv2 -pa --grep UserComment x.jpg
              Exif.Photo.UserComment         Undefined  16  My photo
              $ exiv2 -pv --grep UserComment x.jpg
              0x9286 Photo       UserComment Undefined  16  charset=Ascii My photo

              $ exiv2 -M'set Exif.Photo.UserComment charset=Unicode \u0052\u006f\u0062\u0069\u006e' x.jpg
              $ exiv2 -pa --grep UserComment x.jpg
              Exif.Photo.UserComment                       Undefined  18  Robin
              $ exiv2 -pv --grep UserComment x.jpg
              0x9286 Photo        UserComment                 Undefined  18  charset=Unicode Robin

              $ exiv2 -M'set Exif.GPSInfo.GPSProcessingMethod HYBRID-FIX' x.jpg
              $ exiv2 -pa --grep ProcessingMethod        x.jpg
              Exif.GPSInfo.GPSProcessingMethod             Undefined  18  HYBRID-FIX
              $ exiv2 -pv --grep ProcessingMethod        x.jpg
              0x001b GPSInfo     GPSProcessingMethod       Undefined  18  HYBRID-FIX

              The format for an IPTC Date value is: YYYY-MM-DD (year, month, day)

              The format for an IPTC Time value is: HH:MM:SS (hours, minutes,  seconds)  and  may
              optionally be followed by: -HH:MM or +HH:MM (hours, minutes ahead/behind UTC)

              The  format  of  Rational  (and  SRational)  is one of: integer | integer/integer |
              Fnumber | number
              Rational Examples:

              $ exiv2 "-Mset Exif.Photo.MaxApertureValue 557429/62500" X.jpg
              $ exiv2 "-Mset Exif.Photo.MaxApertureValue F5.6" X.jpg

              The Rational format Fnumber is for the  convenience  of  setting  aperture  values.
              Aperture  values  are stored in Exif is an APEX value which can be evaluated by the
              expression:

              apex-value  =    log(Fnumber) * 2.0 / log(2.0)
              number      = exp(apex-value * log(2.0) / 2.0)

              The Rational format Fnumber is valid for any Rational, even when the key is not  an
              Aperture.     More    information    about    APEX   value   is   available   from:
              http://en.wikipedia.org/wiki/APEX_system

              The format of XMP LangAlt values includes an optional language qualifier:
              lang="language-code" text

              The double quotes around the language-code are optional. If no languge qualifier is
              supplied,  then  the value of "x-default" is used. More information on the language
              format can be found at: https://www.ietf.org/rfc/rfc3066.txt

              $ exiv2 -M'set Xmp.dc.title lang="de-DE" Euros' X.jpg
              $ exiv2 -M'set Xmp.dc.title lang="en-GB" Pounds' X.jpg
              $ exiv2 -M'set Xmp.dc.title lang="en-US" In God We Trust' X.jpg
              $ exiv2 -M'set Xmp.dc.title lang=fr-FR Euros' X.jpg
              $ exiv2 -M'set Xmp.dc.title lang=jp Yen' X.jpg
              $ exiv2 -M'set Xmp.dc.title All others pay cash' X.jpg

              To remove a language specification, set the value to '' (empty string)
              $ exiv2 -M'set Xmp.dc.title lang="en-US"' X.jpg
              To remove all language specifications, delete the key:
              $ exiv2 -M'del Xmp.dc.title' X.jpg
              To register additional XMP namespaces, combine the command with:
              reg prefix namespace

   Command file format
       Empty lines and lines starting with # in a command file are ignored (comments).  Remaining
       lines are commands as described above.

EXIF TAGNAMES AND VALUES

       Exiv2 displays metadata tags and values.

       The  tag  is  a triplet of Family.Group.Tagname.  The following groups are defined for the
       family Exif:

       GPSInfo      Canon           Fujifilm     NikonMe         OlympusFe7        SonyMisc2b

       Exiv2  supports  Exif  2.2  Standard  Tags.   Exiv2  also  supports  reading  and  writing
       manufacturer's   MakerNote.    The  information  in  Exif.Photo.MakerNote  is  encoded  as
       manufacturer's sub-records.  For example, CanonCs are Camera Settings, NikonAf  are  Nikon
       Auto  Focus  records,  NikonCb are Nikon Color Balance Records.  Every tag is defined by a
       unique tagId (16 bit integer) which is unique within a Group.

       You can query Exiv2 groups and tags with the sample program taglist which is documented in
       README-SAMPLES.md

       Exif  Metadata  values  are  defined  in  the Exif Standard.  All data is an array of data
       elements.  The Count defines the number elements in the array.  All elements in  an  array
       have the same type.

       Type               Explanation
        1 BYTE            An 8-bit unsigned integer.
        2 ASCII           7-bit ASCII. NUL terminated.
        3 SHORT           A 16-bit (2-byte) unsigned integer.
        4 LONG            A 32-bit (4-byte) unsigned integer
        5 RATIONAL        Two LONGs. Numerator, denominator.
        7 UNDEFINED       An 8-bit byte.
        8 SSHORT          A 16-bit (2-byte) signed integer.
        9 SLONG           A 32-bit (4-byte) signed integer.
       10 SRATIONAL       Two SLONGs. Numerator, denominator.

       The  printing flag t = translated and is intended for human use.  Scripts should never use
       translated values as they are localised and the format may change as Exiv2  evolves.   The
       printing flag v reports the values recorded in the metadata and should be used by scripts.

Exif DateTime

       An  Exif  DateTime  string  is  stored  as  20 ascii bytes (including trailing nul) in the
       format:

       YYYY:MM:DD HH:MM:SS

       The exiv2 command-line program options -t and -T will accept files in which the  Date  has
       been  incorrectly  stored  as  YYYY-MM-DD.   The  option -a enables the user to adjust the
       DateTime in the file and applies the YYYY:MM:DD HH:MM:SS standard.

CONFIGURATION FILE

       Exiv2  can  read  an  optional  configuration  file   ~/.exiv2   on   Unix   systems   and
       %USERPROFILE%\exiv2.ini  on Windows (using a Visual Studio build).  Cygwin and MinGW/msys2
       follow the unix convention and use  ~/.exiv2   You  can  determine  the  location  of  the
       configuration file with the command:

       $ exiv2 --verbose --version --grep config_path
       exiv2 0.27.0.1
       config_path=/Users/rmills/.exiv2

       The  purpose  of  the  configuration  file is to define your own lenses for recognition by
       Exiv2.  The configuration file is in Windows .ini format and has sections for each of  the
       major  camera manufactures canon,nikon,pentax,minolta,olympus and sony.  The lens metadata
       is stored as a integer called the lensID.  You can change the lens  name  associated  with
       any lensID.

       $ cat ~/.exiv2
       [nikon]
       146=Robin's Sigma Lens  <--- The name of your lens

       You obtain the lensID for your camera with the command:
       $ exiv2 -pv --grep lens/i http://clanmills.com/Stonehenge.jpg
       0x0083 Nikon3       LensType           Byte       1  14
       0x0084 Nikon3       Lens               Rational   4  180/10 2500/10 35/10 63/10
       0x008b Nikon3       LensFStops         Undefined  4  55 1 12 0
       0x000c NikonLd3     LensIDNumber       Byte       1  146 <--- This number
       0x000d NikonLd3     LensFStops         Byte       1  55

EXAMPLES

       $ exiv2 *.jpg
       Prints a summary of the Exif information for all JPEG files in the directory.  The summary
       report is rather brief and presentation does not use the Family.Group.Tag convention.

       If you use --grep pattern, the default becomes -pa.  See -g/grep above.

       $ exiv2 -g Date http://clanmills.com/Stonehenge.jpg

       $ exiv2 -eiX image.jpg
       Extracts IPTC datasets into an XMP sidecar file image.xmp and in the process converts them
       to "IPTC Core" XMP schema.

       $ exiv2 -iixX image.jpg
       Inserts IPTC and XMP metadata from an XMP sidecar  file  image.xmp  into  image.jpg.   The
       resulting  IPTC  datasets  are converted from the "IPTC Core" XMP schema properties in the
       sidecar file to the older IPTC IIM4 format. The inserted XMP properties include  those  in
       the "IPTC Core" XMP schema.

       $ exiv2 -M"set Exif.Photo.UserComment charset=Ascii New Exif comment" image.jpg
       Sets the Exif comment to an ASCII string.

       $ exiv2 -M"set Exif.GPSInfo.GPSLatitude 4/1 15/1 33/1" \ -M"set Exif.GPSInfo.GPSLatitudeRef N" image.jpg
       Sets  the  latitude  to  4  degrees,  15  minutes  and 33 seconds north. The Exif standard
       stipulates that the GPSLatitude tag consists of three Rational numbers  for  the  degrees,
       minutes  and  seconds  of  the  latitude and GPSLatitudeRef contains either 'N' or 'S' for
       north or south latitude respectively.

       $ exiv2 -l/tmp -S.CRW insert /data/*.JPG
       Copy all metadata from CRW files in the /tmp directory to  JPG  files  with  corresponding
       basenames  in  the  /data  directory.  Note  that  this copies metadata as is, without any
       modifications to adapt it to the requirements of the target format. Some tags copied  like
       this may not make sense in the target image.
