when quality or file size is an issue, to the packages collection. 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: 71 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.
