Note this is DEPRECATED repository, all future releases you can find here.
Guetzli is a JPEG encoder that aims for excellent compression density at high visual quality. Guetzli-generated images are typically 20-30% smaller than images of equivalent quality generated by libjpeg. Guetzli generates only sequential (nonprogressive) JPEGs due to faster decompression speeds they offer.
Guetzli is an awesome jpeg encoder, however, it works a little bit slow. In order to speed it up, we have added CUDA support for Guetzli, optimized some procedure.
This repository is only for binary distribution. Please check Releases section.
