cs Color Space

Values

  • srgb: Default (Internet standard)
  • adobergb1998: Adobe’s RGB standard for screen and print
  • tinysrgb: Smaller RGB profile developed at Facebook.
  • strip: Removes all color profile information.

The cs parameter specifies the color space of the output image. Changing or removing the color space information from the image can help decrease file size, especially for smaller images such as thumbnails where color profile information is a larger percentage of the total file size.

srgb refers to the sRGB color space, which is the standard on the Internet, and adobergb1998 refers to the Adobe RGB (1998) color space, which provides accurate color reproduction from screen to print. The tinysrgb value reduces the color space information but may cause a slight shift in color values, and strip removes it completely for maximum file size savings.
