Very nice compression! As others have mentioned, BPG seems to be a bit better at picking which details to save. It's an improvement over mozjpg - even at "tiny" size, the usual (and annoying) "JPEG/MPEG-style block noise" seems to be eliminated. (no offense intended to mozjpeg, which is working from an old spec) -- Speaking of image formats, it might be nice to have a new format where the container is designed to only allow a minimum of features. Something like a file with only [MagicNum, xsize, ysize, xdpi, ydpi, gamma, <compressed pixels>, CRC32]. The idea is that it should NOT support "metadata" like comments or EXIF. As we've seen, there is a problem with getting most people to understand that they should probably strip EXIF/etc before uploading, and having a format where we could say "only upload .foo pictures" instead of "run $tool to strip EXIF". A browser plugin could even auto-convert every image while uploading. Unfortunately, it would face the same problem as any new image format: nobody wants to use a new format until it is already popular.
