WebP codec is a library to encode and decode images in WebP format. This package contains the library that can be used in other programs to add WebP support, as well as the command line tools ‘cwebp’ and ‘dwebp’ to compress and decompress images respectively.

See https://developers.google.com/speed/webp for details on the image format.

The latest source tree is available at https://chromium.googlesource.com/webm/libwebp

It is released under the same license as the WebM project. See https://www.webmproject.org/license/software/ or the “COPYING” file for details. An additional intellectual property rights grant can be found in the file PATENTS.
