The Fastest, Safest PNG Decoder in the World

nigeltao.github.io Summary: Wuffs’ PNG image decoder is memory-safe but can also clock between 1.22x and 2.75x faster than libpng, the widely used open source C implementation. It’s also faster than the libspng, lodepng and stb image C libraries as well as the most popular Go and Rust PNG libraries. High performance is achieved by SIMD-acceleration, 8-byte wide input and copies when bit-twiddling and zlib-decompressing the entire image all-at-once (into one large intermediate buffer) instead of one row at a time (into smaller, re-usable buffers). All-at-once requires more intermediate memory but allows substantially more of the image to be decoded in the
