    FAQ

    Frequently asked questions

    Is my image uploaded anywhere when I adjust saturation?

    No. The image is processed locally in your browser using the Canvas API. It never leaves your device.

    What does 0% saturation look like?

    0% removes all color, which is equivalent to grayscale. 100% is the original, unchanged saturation, and moving the slider above 100% makes colors more vivid.

    Does this change the file format?

    No. The downloaded image is exported in the same format as the original file you uploaded.

    Can I combine this with other adjustments?

    This tool only adjusts saturation. If you also want to change brightness, contrast or convert to grayscale, see the other Image Editing tools, or use Image Filters to adjust all of them together on one page.
