Robust and performant PNG decoder/encoder in pure Rust. Also supports APNG.

No unsafe code, battle-tested, and fuzzed on OSS-fuzz.

Performance is typically on par with or better than libpng.

Includes a fast encoding mode powered by fdeflate that is dramatically faster than the fastest mode of libpng while simultaneously providing better compression ratio.

On nightly Rust compiler you can slightly speed up decoding of some images by enabling the unstable feature of this crate.
