BPG (Better Portable Graphics) is a new image format. Its purpose is to replace the JPEG image format when quality or file size is an issue. Its main advantages are: - High compression ratio. Files are much smaller than JPEG for similar quality. - Supported by most Web browsers with a small Javascript decoder (gzipped size: 56 KB). - Based on a subset of the HEVC open video compression standard. - Supports the same chroma formats as JPEG (grayscale, YCbCr 4:2:0, 4:2:2, 4:4:4) to reduce the losses during the conversion. An alpha channel is supported. The RGB, YCgCo and CMYK color spaces are also supported. - Native support of 8 to 14 bits per channel for a higher dynamic range. - Lossless compression is supported. - Various metadata (such as EXIF, ICC profile, XMP) can be included. - Animation support.
