Really High Efficient File Optimizer will losslessly recompress files as much as possible according to their mime-types
Recompression technique of Artur Jez
Lossless-first recompression for Office, archives, images, PDFs, and data files
A Graphical User Interface for MP3Packer
Repository for all of my work on modelling thermodynamic cycles using python and coolprop ; Hope this might be useful to someone! :-)
Lossless file optimizer and re-compressor
ComicRecompress marries two state of the art technologies: neural network image processing and JPEG-XL
Lossless, byte-exact recompressor for the PNG family — PNG/APNG/JNG/MNG. preflate + WebP-lossless (beats precomp); self-contained cross-platform binary + C library. 2.0 LTS.
Archiver with byte-exact reversible recompression (DEFLATE, JPEG), identical output on x86 and ARM, dedup and FUSE mount. By Vértice Labs.
Recompresses video as x265, high quality, tiny size. Wrapper to ffmpeg.
Human-directed exact recompression research platform with byte-perfect reconstruction, learned entropy contexts, Python research tooling and a native Rust decoder.
