'''BPG''' (Better Portable Graphics) is a compressed raster graphic format created by Fabrice Bellard and intended to have better quality with smaller file sizes than [[JPEG]]. Its compression is based on [[HEVC]], a compression format designed for videos (which may be patent-encumbered in some countries, but which is now being often supported directly by hardware, so if that feature is used instead of separate software it might not require separate licensing). As this format is not natively supported by current browsers, the recommended method of using them in the Web is to include a [[JavaScript]] loader which converts the references to BPG graphics (in normal IMG tags in [[HTML]]) to embedded "data" [[URL]]s containing the graphic data converted to a [[PNG]] graphic.

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.
