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".
- In Photoshop Image Resources metadata, an ICC profile uses Resource ID 0x040F.
