Image Saturation Adjuster
Make dull colours come alive or tone down an over-colourful picture. Use Saturation for an even change, Vibrance for a natural boost that spares skin tones, and Hue shift to rotate every colour.

Colour
Saturation changes every colour equally. Vibrance boosts muted colours more than strong ones, which protects skin tones. Hue shift rotates all colours around the colour wheel.

How to use Image Saturation Adjuster
- Drop one or more images onto the upload area.
- Increase Vibrance for a natural boost, or use Saturation for a stronger, even change. Negative values mute the colours.
- Optionally rotate colours with Hue shift for creative effects.
- Select Apply saturation and download the images.
Image Saturation Adjuster features
Saturation
Scales the intensity of every colour equally, from fully grey to strongly vivid.
Vibrance
Boosts dull colours more than already-strong ones, so skies and foliage gain colour while faces stay natural.
Hue shift
Rotates all colours around the colour wheel for creative recolouring or correcting a colour cast.
Luminance preserved
Colour changes keep each pixel’s perceived brightness, so the image does not get lighter or darker as you adjust.
Batch processing
Give a whole set of images the same colour treatment.
Private by design
Your images stay on your device.
When to use Image Saturation Adjuster
- Making holiday and landscape photos look as vivid as you remember them.
- Muting colours for a calm, editorial or vintage style.
- Toning down neon-bright product photos so they match the real item.
- Creating colour variations of graphics with Hue shift.
- Partially desaturating a background image so text on top stays readable.
Image Saturation Adjuster FAQ
What is the difference between saturation and vibrance?
Saturation changes all colours by the same proportion. Vibrance looks at how colourful each pixel already is and boosts muted pixels more, leaving strongly saturated ones almost untouched. That makes vibrance safer for people, because skin tones quickly turn orange with too much saturation.
How do I make an image black and white?
Set Saturation to −100. For more control over how colours translate into greys, use the Image Grayscale Converter, which offers several conversion methods.
What does Hue shift do?
It rotates every colour by the same angle on the colour wheel: a 120° shift turns reds into greens and greens into blues. Small shifts of a few degrees can correct a slight colour cast.
Why do colours look different on my phone?
Screens differ in their colour range and calibration, and many phones boost saturation by default. Judge adjustments on the device your audience is most likely to use, and avoid extreme values.
Will increasing saturation reveal noise?
Strong saturation can make colour noise in shadows more visible, especially in low-light photos. Vibrance or a smaller saturation boost reduces this.
Colour intensity, explained
Saturation describes how far a colour is from grey. A fully saturated red contains no white or black mixed in; desaturating it moves it towards a grey of the same brightness. The adjustment used here measures each pixel’s luminance, the brightness the eye perceives, and pushes the red, green and blue values away from or towards it. Because luminance is kept fixed, the image does not get lighter or darker as you change the colour intensity.
Vibrance was introduced by photo editing software to solve a practical problem. People, and particularly faces, already contain warm, moderately saturated tones; a global saturation boost turns them orange long before a pale sky looks rich. Vibrance scales the boost by how muted each pixel is, giving the largest increase to the dullest colours. The result reads as more colourful without looking processed.
Hue is a colour’s position on the colour wheel. Shifting it rotates every colour by the same amount while keeping saturation and brightness, a quick way to generate alternative colourways for graphics, or to remove a slight tint. For photographs of real objects, keep hue shifts small; our eyes are very sensitive to unnatural skin and foliage colours.
Many photographers treat colour as the final touch, after exposure and contrast are right. Adjust brightness and contrast first, then saturation or vibrance, and finally sharpen at the output size.
