CAVEATS

Part of the libwebp package. Input format support depends on linked libraries. Very old browsers may not support WebP format. Some image editors have limited WebP support.

HISTORY

WebP was developed by Google and announced in 2010 as an open standard for compressed web images. The format is based on the VP8 video codec and offers significant size reductions compared to traditional formats.
