BPG

BPG (Better Portable Graphics) is a compressed raster graphic format 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" URLs containing the graphic data converted to a PNG graphic.
