ICC profile is a standard format for color management information. It may appear in a file by itself, or embedded in certain graphics file formats.

Contents

Format

An ICC profile has a 128-byte header, followed by an index ("tag table") with a variable number of entries, followed by a data section containing items pointed to by the index.

Related formats

Many graphics-related formats can contain embedded ICC profiles. This is a partial list.

  • In a TIFF file, tag 34675 is used for ICC profiles. See the ICC profile specification for details.
  • In a JPEG file, an APP2 marker with an identifier of "ICC_PROFILE" is used for ICC profiles. See the ICC profile specification for details. Note that large ICC profiles must be split up, to accommodate JPEG's 64KB segment size limit.
  • In a PNG file, chunk type iCCP contains an ICC profile. See the PNG specification for details.
  • In a GIF file, an ICC profile uses application identifier "ICCRGBG1012".
