       img2webp - create animated WebP file from a sequence of input images.


       img2webp [file_level_options] [files] [per_frame_options...]


       This manual page documents the img2webp command.

       img2webp compresses a sequence of images using the animated WebP format.  Input images can
       either be PNG, JPEG, TIFF or WebP.


       The file-level options are applied at the beginning of the compression process, before the
       input frames are read.

       -o string
              Specify the name of the output WebP file.

              Encode images to achieve smallest size. This disables key frame insertion and picks
              the parameters resulting in smallest  output  for  each  frame.  It  uses  lossless
              compression by default, but can be combined with -q, -m, -lossy or -mixed options.

       -kmin int

       -kmax int
              Specify   the   minimum   and  maximum  distance  between  consecutive  key  frames
              (independently decodable frames) in the output animation. The tool will insert some
              key frames into the output animation as needed so that this criteria is satisfied.
              -mixed  Mixed compression mode: optimize compression of the image by picking either
              lossy or lossless compression for each  frame  heuristically.  This  global  option
              disables the local option -lossy and -lossless .

       -loop int
              Specifies  the  number  of  times  the animation should loop. Using '0' means 'loop

       -v     Be more verbose.

       -h, -help
              A short usage summary.


       The per-frame options are applied for the images following as  arguments  in  the  command
       line. They can be modified any number of times preceding each particular input image.

       -d int Specify the image duration in milliseconds.

       -lossless, -lossy
              Compress  the  next  image(s) using lossless or lossy compression mode. The default
              mode is lossless.

       -q float
              Specify the compression factor between 0 and 100. The default is 75.

       -m int Specify the compression method to  use.  This  parameter  controls  the  trade  off
              between  encoding  speed and the compressed file size and quality.  Possible values
              range from 0 to 6. Default value is 4.
