BPG (Better Portable Graphics) is a compressed raster graphic format, using HEVC to encode pictures. Animation, deep color, and metadata are supported. The format is experimental and not natively supported by browsers; a Javascript loader is available that converts BPG to PNG for display. The bitstream format is very similar to raw HEVC.
image/bpg has been suggested for the MIME type, but none is formally registered.
