JPEG Lossless Recompression
Future of image compression with utmost respect to our digital heritage.·brunsli.dev
A browser-based tool that losslessly converts JPEG (.jpg) files into the Brunsli (.brn) format, reducing file size by about 22% while preserving all original image data byte-by-byte. The conversion runs entirely locally in the browser using WebAssembly, so images are never uploaded to a server. Currently only .jpg files are supported; .png and .gif are not.
