Lepton image compression, saving 22% losslessly from images at 15MB/s. Lepton achieves a 22% savings reduction for existing JPEG images, by predicting coefficients in JPEG blocks and feeding those predictions as context into an arithmetic coder. Lepton preserves the original file bit-for-bit perfectly. It compresses JPEG files at a rate of 5 megabytes per second and decodes them back to the original bits at 15 megabytes per second, securely, deterministically, and in under 24 megabytes of memory. We have used Lepton to encode 16 billion images saved to Dropbox, and are rapidly recoding our older images. ...

BCM is a high-performance file compressor that utilizes advanced context modeling techniques to achieve a very high compression ratio. All in all, it's like a big brother of the BZIP2.
