JPEG Lossless Recompression
.jpg ⇄ .brn

Future of image compression with utmost respect to our digital heritage.

JPEG files can be transformed into the Brunsli form without quality loss, while reducing their size by 22%. Brunsli preserves all the data in a more efficient container, where the integrity of an original photograph is maintained byte-by-byte — without damage to our digital cultural heritage.

On this page you can be one of the first to try out the new compression technology on your photographs. The conversion process runs locally in your browser using WebAssembly technology, no images are uploaded to servers. This demo only works with .jpg files, there is no .png nor .gif support at the moment.
