Color Space
A color space defines the range of colors an image can represent and how numeric values map to visible hues. sRGB is the standard color space for web and most consumer displays. Adobe RGB and ProPhoto RGB encompass wider gamuts useful in professional photography and print, but colors outside sRGB may look dull or shifted when converted for screens that cannot display those extremes.
Embedded ICC profiles in image files tell software how to interpret color values. Mismatched profiles can make the same file look washed out in one viewer and oversaturated in another. Converting to sRGB before web export stabilizes appearance across browsers and compression tools. Compression itself does not fix color problems—it encodes whatever pixels are present.
When FileShrinkr compresses JPG or WEBP, output colors follow the processed pixel data from your upload. If skin tones or brand colors look wrong after compression, check source color space and convert to sRGB in an editor before upload. Consistent color space handling pairs with format and quality choices for predictable publishing results.
