       pdfpc - PDF presenter console with multi-monitor support


       pdfpc [options] PDF-file


       pdfpc  is  a GTK-based presentation viewer which uses Keynote-like multi-monitor output to
       provide meta information to the speaker during the presentation. It  is  able  to  show  a
       normal  presentation  window  on one screen while showing a more sophisticated overview on
       the other one, providing information like a picture of the next slide, as well as the time
       left in the presentation. pdfpc processes PDF documents, which can be created using nearly
       all modern presentation software.

       By default the presenter view appears in the primary monitor and the presentation view  in
       the second monitor (provided you have two monitors).


       -B, --list-bindings
              List action bindings defined

       -C, --time-of-day
              Display the time of the day

       -d, --duration=N
              Duration  in minutes of the presentation used for timer display. If not given or if
              a value of 0 is specified, the clock just measures the time in the presentation.

       -e, --end-time=T
              End time of the presentation. (Format: HH:MM (24h))

       -f, --note-format=FORMAT
              Enforce format of notes (plain or markdown. Default: markdown)

       -g, --disable-auto-grouping
              Disable auto detection of overlay groups. (Default: enabled)

       -h, --help
              Show this help

       -l, --last-minutes=N
              In the old timer mode (see Timer below), defines time in minutes before the end  of
              the talk when the timer changes its color.  (Default: 5 minutes)

       -L, --list-actions
              List actions supported

       -M, --list-monitors
              List monitors known to the operating system

       -n, --notes=P
              Position  of  second-screen beamer notes on the PDF page (left, right, top, bottom,
              or none. Default: none). Note that this disables slide auto-grouping.

       -N, --no-install
              Allow for testing pdfpc without proper installation.  Icons,  configuration  files,
              etc. will be loaded from the source path locations. Mostly intended for developers.

       -P, --page
              Go  to a specific page directly after startup. In case of overlays, the first slide
              will be displayed.

       -r, --page-transition=TRANSITION
              Set  default  page  transition.  The  TRANSITION  specification  is  of  the   form
              type:duration:angle:alignment:direction.  See  the Page transitions section for the
              list of supported types. duration is  in  seconds.  The  three  last  settings  are
              optional  (and  indeed meaningless for some of the transition types).  The accepted
              values for angle are 0/90/180/270; alignment can be h[orizontal] of v[ertical]  and
              direction i[nward] or o[utward].

       -R, --pdfpc-location=LOCATION
              Use custom pdfpc file.

       -s, --switch-screens
              Switch the presentation and the presenter screen.

       -S, --single-screen
              Force to use only one screen

       -t, --start-time=T
              Start time of the presentation to be used as a countdown. (Format: HH:MM (24h))

       -T, --enable-auto-srt-load
              Try  loading  video  subtitle files automatically. For each video media, pdfpc will
              append ".srt" to the media URI and attempt to load a  subtitle  file  (in  the  SRT
              format) from that location.

       -W, --wayland-workaround
              Enable Wayland-specific workaround. This might fix HiDPI scaling problems.

       -w, --windowed=MODE
              Run in the given windowed mode (presenter|presentation|both|none). The default mode
              is "none" (both windows are fullscreen).

       -X, --external-script=FILENAME
              Specify a script to be executed with the 'X' (Shift+x) key during the presentation.
              The  script  must  be  executable but can otherwise be written in any language. The
              script is called with the following command line arguments:

              • Name of pdf file
              • Total slide count
              • Current slide number
              • Current user slide number

              If the script exits with a non-zero return value,  whatever  the  script  wrote  to
              stdout is printed in the console. Otherwise nothing is printed.

       -Z, --size
              Size of the presentation window in width:height format (forces windowed mode)

       -1, --presenter-screen=MONITOR
              Monitor to be used for the presenter screen (see the -M option).

       -2, --presentation-screen=MONITOR
              Monitor to be used for the presentation screen (see the -M option).

       Cursor right / Page down
              Select next slide

       See  pdfpcrc(5)  if  you  want to customize the key or mouse bindings. Please note though,
       that only in the normal mode the mouse bindings are configurable.


   Caching / Pre-rendering
       To allow fast changes between the presentation slides, the PDF pages are  pre-rendered  to
       memory.  The progress bar on the bottom of the presenter screen indicates how many percent
       of the slides have been pre-rendered already.  During the  initial  rendering  phase  this
       will  slow  down slide changes, as most CPU power is used for the rendering process in the
       background.  After the cache is fully primed, however, the changing of  slides  should  be
       much faster, as with normal PDF viewers.

       To avoid excessive memory consumption, cached are only slides that took a significant time
       to render; this threshold is configurable. In order to further reduce memory  consumption,
       the  pre-rendered  and cached slides are selectively compressed in memory. The compression
       factor is typically 10-30, however, it takes some CPU time to compress and uncompress,  so
       there  is  a  trade-off. Small images below a certain (configurable) threshold will not be

       Please refer to the pdfpcrc(5) man page for options to fine tune the caching algorithm.

       If a duration is given (-d option), the  timer  will  show  a  countdown  with  the  given
       parameters.   If  no duration is specified (or if a value of 0 is given to the -d option),
       the timer will show how much time has been spent.  The duration is  stored  automatically,
       so you do not need to repeat it for every invocation.

       The  timer  is  started if you are navigating away from the first page for the first time.
       This feature is quite useful as you may want to show the title page of  your  presentation
       while  people  are  still entering the room and the presentation has not really begun yet.
       If you want to start over you can use the 'Ctrl + t' key which  will  make  the  presenter
       reset the timer.

       If  a  duration  is  given,  the  timer  also provides hints aiding the presenter to judge
       whether the talk would end on time.  There are two modes in which pdfpc can  operate.   In
       the  old (and the only one available up to, and including pdfpc-4.0.8) mode, at the moment
       the timer reaches the defined last-minutes value it will change  color  to  indicate  your
       talk is nearing its end, thus mimicking a chairman frantically pantomiming in front of you
       with five (four, three, ...) fingers up.  A drawback of this approach is it is  often  too
       late at that moment to alter the presentation pace without ruining to some extent the rest
       of the  talk.   On  the  other  hand,  the  warning  indication  provides  an  unnecessary
       distraction  if  you  have  been  perfectly  conveying  the talk and the remaining time is

       Contrary to that, in the new (default) mode,  pdfpc  tracks  your  progress  continuously,
       calculating    the   expected   time   as   (talk_duration)*(current_user_slide_number   -
       0.5)/(total_number_of_user_slides)  and  comparing  it  to  the  actual  wall  time  since
       beginning  of  the  talk.   If these two numbers differ by more than 60 seconds, the timer
       changes its color to either orange (indicating you need to speed  up)  or  a  blueish  one
       (need  to  slow  down).   Once  the optimal progress is recovered, the timer becomes white
       again.  In this mode, the last-minutes option (-l) has no effect.  The  previous  behavior
       can  be  restored by setting the 'timer-pace-color' option to 'false' in the configuration
       file, see pdfpcrc(5).

       In any case as soon as the timer reaches the zero mark (00:00:00), it will  turn  red  and
       count further down showing a negative time, to provide information on how many minutes you
       are overtime.

       Textual notes can be displayed for each slide.  pdfpc  understands  the  Markdown  syntax,
       which  allows  for  rendering  anything  from  plain text to a very rich formatting, if so
       desired.  A few types of PDF annotations are understood by pdfpc and will be automatically
       imported  and  displayed.  The PDF annotations can be made using many PDF editors and even
       viewers;  when using LaTeX, the pdfpc package (see below)  provides  a  convenient  macro.
       These "native" PDF notes cannot be edited in pdfpc.

       In addition, while in the presentation mode, pressing 'Ctrl + n' will allow you to take or
       edit notes for the current user slide.  To exit the note editing mode,  press  the  Escape
       key.  These notes are stored in the .pdfpc file.  They take precedence over the native PDF
       annotations, i.e., if a user-provided note exists for a given slide, any  PDF  annotations
       on  that  page  will be silently ignored. While editing a note, the normal keybindings are
       disabled, e.g., you are not able to change slides.

       Although mixing the two types of notes is possible, for  a  given  presentation  one  will
       likely  want  to  have  either only the "native" notes (produced by the same PDF authoring
       software used for making the slides), or only the "pdfpc" ones.

   Overview mode
       Pressing the Tab key enters the overview mode, where thumbnails of the slides are shown in
       a grid.  You can select a slide to jump to with the mouse or with the arrow keys.  You can
       also define overlays and the end slide (see next sections) in this mode.  Press Escape  to
       exit the mode without making an change.

       Many slide preparation systems allow for overlays, i.e.  sets of slides that are logically
       grouped together as a single, changing slide.  Examples include enumerations where  bullet
       items  are  displayed  one  after another, or rough "animations", where parts of a picture
       change from slide to slide. Pdfpc includes facilities for dealing with such overlays.

       In this description, we  will  differentiate  between  slides  (i.e.   pages  in  the  PDF
       document)  and  "user slides", that are the logical slides.  The standard forward movement
       command (page down, enter, etc.) moves through one slide at a  time,  as  expected.   This
       means  that  every  step in the overlay is traversed.  The backward movement command works
       differently depending on whether the current and previous slides are part of an overlay:

       • If the current slide is part of an overlay we just jump to  the  previous  slide.   That
         means  that we are in the middle of an overlay and can jump forward and backward through
         the single steps of it

       • If the current slide is not part of an overlay (or if it is  the  first  one),  but  the
         previous  slides  are,  we  jump to the previous user slide.  This means that when going
         back in the presentation you do not have to go through every step of the overlay,  pdfpc
         just  shows  the  first  slide  of  each  overlay.   As  one  typically  goes  back in a
         presentation only when looking for a concrete slide, this is more convenient.

       The Shift + Page up/down key combinations work on the "user slide"  basis.   You  can  use
       them  to  skip  the rest of an overlay or to jump to the previous user slide, ignoring the
       state of the current slide.

       When going through an overlay, two additional previews may be activated in  the  presenter
       view, just below the main view, showing the next and the previous slide in an overlay.

       Pdfpc  tries  to  find these overlays automatically by looking into the page labels in the
       PDF file.  For LaTeX this works  correctly  at  least  with  the  beamer  class  and  also
       modifying  the  page numbers manually (compiling with pdflatex).  If your preferred slide-
       producing method does not  work  correctly  with  this  detection,  you  can  supply  this
       information using the 'Ctrl + o' key for each slide that is part of an overlay (except the
       first one!).  The page numbering is  also  adapted.   This  information  is  automatically

   End slide
       Some people like to have some additional, backup slides after the last slide in the actual
       presentation.  Things like bibliographic references or  slides  referring  to  specialized
       questions  are  typical  examples.   Pdfpc  lets you define which is the last slide in the
       actual presentation via the 'Ctrl + e' key.  This just changes the progress display in the
       presenter screen, as to have a better overview of how many slides are left.

   Page transitions
       Pdfpc  supports  almost  all  standard  animated PDF page transitions: blinds, box, cover,
       dissolve, fade, glitter (except  the  diagonal  one),  push,  split,  uncover,  and  wipe,
       including  various  alignments, angles, and directions (where applicable). The transitions
       are enabled only for sequential (either forward or backward) movement; in the later  case,
       the transition is "inverted".

       Advancing slides automatically is also supported.

       Pdfpc can play back movies included in the PDF file.  Movies may be started and stopped by
       clicking within their area.  For the presenter, a progress bar is drawn along  the  bottom
       of  the  movie.   This  expands  when  the  mouse  hovers over it, allowing one to seek by
       clicking or dragging within  the  progress  bar.   Switching  slides  automatically  stops
       playback, and movies will be reset after leaving and returning to a slide.

       Movies  may  be included in PDF files as "screen annotations".  pdfpc does not yet support
       options that modify the playback of these movies.  In LaTeX, such movies may be added to a
       presentation  with  the "movie15" or "multimedia" package. Note that the poster, autoplay,
       and repeat options are not yet supported. (Also, run ps2pdf with the -dNOSAFER flag.)

       As a perhaps simpler option, pdfpc will play back movies linked from a hyperlink  of  type
       "launch".   A query string may be added to the URL of the movie to enable the "autostart",
       "loop"   and   "noprogress"   properties,   if    necessary.     (E.g.,    a    link    to
       "movie.avi?autostart&loop&noprogress"  will add a video that starts playing automatically,
       loops when it reaches the end, and does not show the progress bar.)

       In LaTeX, such links are created with

              \href{run:<movie file>}{<placeholder content>}

       The movie will playback in the area taken by the placeholder content.  Using  a  frame  of
       the movie will ensure the correct aspect ratio.

       See our website ⟨⟩ for a full example.

       See the bugs section for further information.

   Pointer mode
       If  needed,  it is possible to turn on a pointer which draws a red (by default) dot in the
       place pointed by mouse cursor on both presenter  and  presentation  screens.  It  is  also
       possible  to  increase  and  decrease the pointer size.  Additionally, when the pointer is
       enabled, it is possible to highlight some area of the current slide using the  drag  mouse
       motion.  The area outside the selected region will be dimmed. You can zoom in the selected
       area by pressing 'z'; press 'Escape' to exit the zoom  mode.  You  can  highlight  another
       region  while  zoomed  in, but there will be no further action on pressing 'z'. Drawing is
       also disabled in this mode.

   Spotlight mode
       Spotlight mode is similar to the pointer mode: a circular area that moves with  the  mouse
       and can be adjusted in size, but instead of highlighting the spot by a different color, it
       shades the background.

   Drawing mode
       It is possible to turn on a mode which allows drawing over slides with the mouse cursor or
       a  connected  tablet.  When drawing mode is enabled, drawings can be made on the presenter
       screen. A separate drawing will be kept in memory for each  slide  (based  on  user  slide
       numbers,  so  consolidating  overlay  slides).  Drawings  are  presently not saved between

       In the drawing mode, there are two drawing tools, a pen and an eraser. An indicator in the
       bottom-left  corner of the presenter screen will indicate which is active. When in the pen
       mode, the color and size of the pen will be indicated by the cursor. The pen size  can  be
       increased  or decreased using hot keys specified in the key bindings. When the eraser tool
       is active, the size of the cursor indicates the amount to erase.

       The color of the pen can be changed through key bindings or using the toolbox.

       If you are using a tablet, the pen or eraser tool will be selected based  on  whether  the
       tablet reports a pen or eraser input device is being used, overriding the normal selection
       of the drawing tool. Also for pressure-sensitive input devices, the pressure  will  affect
       the  line  width  and  the  eraser  size.   Both  these  features  can  be disabled in the
       configuration file, if desired.

   Monitor Plug and Play
       Pdfpc can handle monitor plug and play. E.g. if pdfpc was started before the  presentation
       screen  was  attached  to  the computer, pdfpc can create and show the presentation screen
       after the second screen was attached. This allows the user  to  rehearse  the  slides  and
       switch to a normal presentation without having the full setup at the computer in advance.

   pdfpc files
       Notes,  user-defined  overlays,  and  some additional information is stored in a file with
       extension "pdfpc".  When pdfpc is invoked with a PDF file, it automatically checks for and
       loads  the associated .pdfpc file, if it exists.  This means that you normally do not have
       to deal with this kind of files explicitly.

       Beside internal configuration, the following command-line options are saved in  the  pdfpc
       file for later usage:

       • duration

       • end_time

       • last_minutes

       • notes (position)

       • page_transition

       • start_time

       With  GTK3 it is possible to modify the appearance of pdfpc. There are two locations where
       pdfpc is looking for files. The default location is /usr/share/pixmaps/pdfpc/pdfpc.css. It
       can be copied to $XDG_CONFIG_HOME/pdfpc/pdfpc.css and modified to the user's liking.

       The  geometry of various views (the current/next etc slide) in the presenter window can be
       adjusted at run time in the "Customization" mode, which is activated by pressing  Shift+c.

   Desktop integration
       Pdfpc  provides a DBus interface that appears on the session bus as io.github.pdfpc. Other
       applications can, in particular, execute any action listed by --list-actions. It  is  also
       possible  to control pdfpc from the command line (and write shell scripts) using the dbus-
       send(1) utility. For example, to advance to the next slide, run

       dbus-send --type=method_call --session --dest=io.github.pdfpc
        /io/github/pdfpc io.github.pdfpc.TriggerAction string:next

       For actions that require an argument, use TriggerActionArg, e.g.,

       dbus-send --type=method_call --session --dest=io.github.pdfpc
        /io/github/pdfpc io.github.pdfpc.TriggerActionArg string:switchMode

       In addition to TriggerAction*, the pdfpc DBus interface exposes the GetNotes method, three
       properties  (NumberOfOverlays,  NumberOfSlides,  Url)  and  two signals (OverlayChange and

   LaTeX package
       A tiny LaTeX package is available for pdfpc at CTAN.  It  provides  a  convenient  way  to
       specify  notes  and  to  define  certain  meta properties of the presentation.  For a full
       documentation, please consult the pdfpc package documentation. You can open it with:

              $ texdoc pdfpc


       Bugs can be reported at our issue tracker ⟨⟩.

       The LaTeX package "hyperref" produces buggy results when using with beamer  notes.  It  is
       recommended to use the "multimedia" package instead.


       pdfpc was previously developed by davvil ⟨⟩.

       pdfpc is a fork of Pdf Presenter Console, available online ⟨



       There are several other programs with similar functionality.

       impressive(1) has nice transition effects.

       hpdfp(1) is the Haskell PDF Presenter ⟨
       haskell-pdf-presenter/⟩  program,  which  packs an amazing level of functionality into not
       many lines of Haskell.

       pympress(1) is a little PDF reader written in Python ⟨⟩
       which handles dual screens and beamer notes.

       dspdfviewer(1) is a specialized Dual-Screen PDF Viewer for latex-beamer ⟨https://⟩ for beamer-produced wide PDF with notes on the right.

       Many PDF viewers have full-screen presentation modes, but without dual-monitor preview  or
       notes or a timer. These include zathura(1), evince(1), and okular(1).
