Frequently asked questions

How do I change the saturation of an image?
Upload your image and move the saturation slider. Increasing it intensifies every color; dragging it toward -100 fades the image to grayscale. The live preview updates as you drag, so you can dial in the exact look before downloading.
How do I increase the color intensity of an image?
Raise the saturation slider, and optionally contrast, to make colors more vivid. A vibrance-style boost is also available, which lifts muted colors more than already-saturated ones so skin tones stay natural.
What is the difference between saturation and vibrance?
Saturation increases the intensity of all colors equally. Vibrance boosts muted colors more than already-saturated ones, making it better for photos with skin tones because it avoids making faces look orange.
Can I saturate or desaturate photos in batch?
Yes. Set your saturation and color adjustments on one image, then batch process the rest. Every image receives the same settings, keeping a set visually consistent.
