BPG (Better Portable Graphics) is a new image format.

[edit] Features

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, YCoCg and CMYK color spaces are also supported.
  • Native support of 8 to 14 bits per channel for a higher dynamic range. (HDR)
  • Lossless compression is supported.
  • Various metadata (such as Exif, ICC Profile, XMP) can be included.
  • Animation support.
  • BPG can be supported in hardware with standard HEVC decoders and encoders
