# QOI - The “Quite OK Image” format for fast, lossless image compression
Single-file MIT licensed library for C/C++
See [qoi.h](https://github.com/phoboslab/qoi/blob/master/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.
⚠️ 2021.11.30 the file format is not yet finalized. We're still working to fix
some smaller issues. The final specification will be announced on 2021.12.20.
Thanks for your patience! https://github.com/phoboslab/qoi/issues/48
These specification changes are ~~not yet reflected in the code here~~
reflected in qoi.h now.
## 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](https://github.com/phoboslab/qoi/blob/master/qoiconv.c)
converts between png <> qoi
- [qoibench.c](https://github.com/phoboslab/qoi/blob/master/qoibench.c)
a simple wrapper to benchmark stbi, libpng and qoi
