BPG Image format
▻http://bellard.org/bpg
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.
