Lepton is a tool and file format for losslessly compressing JPEGs by an average of 22%.

Dockerized PHP7 application runs as a Microservice to resize and crop images on the fly. Get optimised images with MozJPEG, WebP or PNG using ImageMagick. Includes face detection, cropping, face blurring, image rotation and many other options. Abstract storage based on FlySystem in order to store images on any provider (local, AWS S3...).

Building better compression together

The Minimal LZMA (minlzma) project aims to provide a minimalistic, cross-platform, highly commented, standards-compliant C library (minlzlib) for decompressing LZMA2-encapsulated compressed data in LZMA format within an XZ container, as can be generated with Python 3.6, 7-zip, and xzutils
