Из PNG в BGP

PNG is a raster image format developed by PNG Development Group. The name PNG is an abbreviation for Portable Network Graphic. This image format is used primarily on the Internet for posting on web pages, since PNG files use Deflate compression without losing quality. The development of this format was undertaken in order to replace the GIF format, to which there were many complaints. PNG's image quality and specifications were much better, but unlike GIF, it does not support animation and uses the CMYK palette.

BPG is a new graphic format developed by French programmer Fabrice Bellard, known as the creator of the popular programs FFmpeg, QEMU, LZEXE. The main task of the new format is to become a replacement, first of all, for the super popular JPEG image format. According to the developer, such a replacement is necessary where the file size or quality is of great importance. BPG (full name Better Portable Graphics) has a high compression ratio, which, when equal to JPEG quality, allows you to make files much smaller. Moreover, compression is possible without loss. Since the BPG format also supports animation, this gives rise to forecasts that this particular format can successfully compete and eventually replace the animated GIF on the Internet, since it surpasses it in all respects. So, GIF-animation of similar quality will have a much larger size. The BPG format is based on a subset of the HEVC open video compression technology. Mozilla research has shown that HEVC coding demonstrates clear superiority over other technologies. However, the HEVC standard does not have perfect patent purity, and therefore many browsers so far refrain from supporting BPG. Therefore, to download images by most web browsers, you need to use a special Javascript decoder.
