A Go library for encoding and decoding WebP images using C bindings to libwebp.
go-webp is a Go library that provides encoding and decoding capabilities for WebP images by leveraging C bindings to Google's libwebp library. It offers a native Go interface for working with the modern WebP image format, which provides superior compression compared to JPEG and PNG while maintaining quality.
Go developers who need to process WebP images in their applications, particularly those requiring high-performance encoding and decoding with support for both lossy and lossless compression.
Developers choose go-webp for its significantly faster performance compared to alternative Go implementations, direct integration with Google's optimized libwebp C library, and a simple, familiar API similar to standard Go image packages.

The README's benchmarks show go-webp decoding is 2-4x faster than alternative implementations like XImage, making it ideal for performance-critical image processing.
It provides familiar Decode and Encode functions similar to standard Go image packages, as shown in the examples, reducing the learning curve for developers.
Direct C bindings to Google's libwebp library ensure reliable and efficient WebP handling, leveraging the industry-standard implementation for compression.
It handles both lossy and lossless WebP formats, as highlighted in the key features, offering flexibility for different image quality needs.
Requires libwebp to be installed separately on the system, which complicates setup and deployment, especially in cross-platform or restricted environments.
The TODO list admits missing features like incremental decoding and container API, limiting advanced use cases without custom implementation.
Installation steps are only provided for MacOS and Linux, and reliance on CGO can cause problems on platforms where it's unsupported or disabled.
