libwebp is the reference C library for encoding and decoding images in the WebP format, maintained by the WebM project. It also ships command-line tools such as cwebp and dwebp for compressing and decompressing images.
Use cases
- add WebP encoding support to an application
- convert PNG or JPEG images to WebP from the command line
- decode WebP images in a C or C++ program
- compress images for faster web page loading
- handle animated WebP files
- inspect WebP image metadata and info
When to choose
- you need fast, well-supported WebP encode/decode in native code
- you want the canonical implementation of the WebP format
- you need simple CLI tools for batch image conversion
When to avoid
- you need a general-purpose image library supporting many formats
- you want a high-level API in a language other than C without bindings
- you only need to display images rather than encode/decode them
