No input file(s) for generating animation!
Usage:
img2webp [file_options] [[frame_options] frame_file]... [-o webp_file]
File-level options (only used at the start of compression):
-min_size ............ minimize size
-kmax <int> .......... maximum number of frame between key-frames
(0=only keyframes)
-kmin <int> .......... minimum number of frame between key-frames
(0=disable key-frames altogether)
-mixed ............... use mixed lossy/lossless automatic mode
-near_lossless <int> . use near-lossless image preprocessing
(0..100=off), default=100
-sharp_yuv ........... use sharper (and slower) RGB->YUV conversion
(lossy only)
-loop <int> .......... loop count (default: 0, = infinite loop)
-v ................... verbose mode
-h ................... this help
-version ............. print version number and exit
Per-frame options (only used for subsequent images input):
-d <int> ............. frame duration in ms (default: 100)
-lossless ............ use lossless mode (default)
-lossy ............... use lossy mode
-q <float> ........... quality
-m <int> ............. compression method (0=fast, 6=slowest), default=4
-exact, -noexact ..... preserve or alter RGB values in transparent area
(default: -noexact, may cause artifacts
with lossy animations)
example: img2webp -loop 2 in0.png -lossy in1.jpg
-d 80 in2.tiff -o out.webp
Note: if a single file name is passed as the argument, the arguments will be
tokenized from this file. The file name must not start with the character '-'.
Supported input formats:
WebP, JPEG, PNG, PNM (PGM, PPM, PAM)
