|IMG2WEBP(1)||General Commands Manual||IMG2WEBP(1)|
img2webp compresses a sequence of images using the animated WebP format. Input images can either be PNG, JPEG, TIFF or WebP. If a single file name (not starting with the character '-') is supplied as the argument, the command line arguments are actually tokenized from this file. This allows for easy scripting or using a large number of arguments.
- -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 the 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 indefinitely'.
- Be more verbose.
- -h, -help
- A short usage summary.
- Print the version numbers of the relevant libraries used.
- -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.
