## Why? ## Why?
Compared to stb_image and stb_image_write QOI offers 20x-50x faster encoding, QOI offers sweet-spot of compression ratio and throughput for lossless
3x-4x faster decoding and 20% better compression. It's also stupidly simple and image encoding. QOI's compression is roughly comparable to PNG (usually worse than
fits in about 300 lines of C. [libPNG](https://github.com/pnggroup/libpng), but better than [stb_image_write.h](https://github.com/nothings/stb/blob/master/stb_image_write.h)), while throughput is a lot higher.
Benchmark results on a few thousand images can be found here: https://qoiformat.org/benchmark/
The QOI format is also extremely simple, which helps a lot when porting to other languages.
