QOI - The “Quite OK Image” format for fast, lossless image compression

Single-file MIT licensed library for C/C++

See qoi.h for the documentation.

More info at https://phoboslab.org/log/2021/11/qoi-fast-lossless-image-compression

⚠️ Please note that this library is not yet ready to deal with untrusted input.

Why?

Compared to stb_image and stb_image_write QOI offers 20x-50x faster encoding, 3x-4x faster decoding and 20% better compression. It's also stupidly simple and fits in about 300 lines of C.

Example Usage

qoiconv.c converts between png <> qoi
qoibench.c a simple wrapper to benchmark stbi, libpng and qoi
