+
+# 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 and format specification.
+
+More info at https://qoiformat.org
+
+
+## Why?
+
+QOI offers sweet-spot of compression ratio and throughput for lossless 
+image encoding. QOI's compression is roughly comparable to PNG (usually worse than 
+[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.
+
+
+## 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
+
+
+## MIME Type, File Extension
+
+The recommended MIME type for QOI images is `image/qoi`. While QOI is not yet
+officially registered with IANA, I believe QOI has found enough adoption to
+prevent any future image format from choosing the same name, thus making a 
+MIME type collision highly unlikely ([see #167](https://github.com/phoboslab/qoi/issues/167)).
+
+The recommended file extension for QOI images is `.qoi`
+
+
+## Limitations
+
+The QOI file format allows for huge images with up to 18 exa-pixels. A streaming 
+en-/decoder can handle these with minimal RAM requirements, assuming there is 
+enough storage space.
+
+This particular implementation of QOI however is limited to images with a 
+maximum size of 400 million pixels. It will safely refuse to en-/decode anything
+larger than that. This is not a streaming en-/decoder. It loads the whole image
+file into RAM before doing any work and is not extensively optimized for 
+performance (but it's still very fast).
+
+If this is a limitation for your use case, please look into any of the other 
+implementations listed below.
+
+
+## Improvements, New Versions and Contributing
+
+The QOI format has been finalized. It was a conscious decision to **not** have a
+version number in the file header. If you have a working QOI implementation today, 
+you can rest assured that it will be compatible with all QOI files tomorrow.
+
+There are a lot of interesting ideas for a successor of QOI, but none of these will 
+be implemented here. That doesn't mean you shouldn't experiment with QOI, but please
+be aware that pull requests that change the format will not be accepted.
+
+Likewise, pull requests for performance improvements will probably not be accepted
+either, as this "reference implementation" tries to be as easy to read as possible.
