On a Debian-like system the following should install everything you need for a minimal build: $ sudo apt - get install build - essential cmake Building PrerequisitesĪ compiler (e.g., gcc 6+, clang 7+ or Microsoft Visual Studio 2017+ are recommended) and CMake. The goal is to reach decompression speed parity. It still compresses 2x faster than AVIF, but takes 3x more time to decompress. WebP2 is currently only partially optimized and, roughly speaking 5x slower than WebP for lossy compression. WebP 2 is primarily tuned for the typical content available on the Web and Mobile apps: medium-range dimensions, transparency, short animations, thumbnails. The use cases remain mostly the same as WebP: transfer over the wire, faster web, smaller apps, better user experience.

strong focus on software implementation, fully multi-threaded.small container overhead, tailored specifically for image compression.better visual degradation at very low bitrate.more efficient lossy compression (~30% better than WebP, as close to AVIF as possible).The new features (like 10b HDR support) are kept minimal. The WebP 2 experimental codec is mostly pushing the features of WebP further in terms of compression efficiency.
