Getting cwebp, dwebp, and the WebP Libraries
cwebp encodes images in either JPEG, PNG or TIFF format into WebP, while
dwebp decodes them back into PNG. For a quick and easy way to get started
converting your images, the following archives are available on the
libwebp-1.2.1-windows-x64.zip : 64-bit executables and libraries for Windows-x64 platform.
libwebp-1.2.1-linux-x86-64.tar.gz : 64-bit executables and libraries for GNU/Linux-x86_64 platform.
libwebp-1.2.1-mac-10.15.tar.gz : 64-bit executables and libraries for macOS 10.15+ (Catalina) platform.
All these archives contain the full suite of utilities including
gif2webp, along with the WebP libraries and C headers (the
latter allowing you to add WebP encoding or decoding to your own programs).
Note (for Linux and macOS):
The binaries have been statically linked for compatibility across releases and distributions. However, if the binaries fail to run on your platform, check the Compiling the Utilities page for instructions on how to build your own versions.
