Increase Image Saturation
Make colors richer and more vivid, or pull them back for a muted look. The saturation slider runs both ways, with warmth and contrast alongside it — all processed on your device.

Saturation, and how far to take it
Saturation is how pure a color is: at zero every hue collapses to gray, and as it rises the colors move further from gray toward their most intense version. A modest boost is one of the most satisfying edits there is — an overcast landscape or a dull product photo comes alive with very little effort.
The failure mode is specific and worth watching for. Skin tones turn orange long before the rest of the image looks over-saturated, and strong reds and blues are the first channels to clip, losing their internal detail and turning into flat patches of color. If a photo has people in it, less is almost always more.
The controls that go with it
Saturation is often not the right tool on its own. If a photo looks lifeless because it is flat rather than because it lacks color, contrast — or Auto levels — will fix it far more convincingly, and this page pairs a saturation boost with a small contrast increase for that reason. If the problem is a color cast rather than weak color, the warmth slider corrects the blue-orange balance directly, and the hue control rotates every color at once for deliberately stylized results.
Going the other way is just as useful: reducing saturation produces the restrained, muted palette that suits backgrounds, moodboards and text overlays, and taking it all the way to -100 is a straight black and white conversion.

Frequently asked questions
- Is my image uploaded to adjust it?
- No. Every adjustment is computed on a canvas inside your browser, so the photo never leaves your device and no server ever sees it.
- How do I make an image black and white?
- Set the “Black & white” slider to 100% — or click the B&W look, which also adds a little contrast so the result does not look flat. Noir goes further with a much harder contrast curve.
- What does inverting the colors do?
- It replaces every color with its opposite, which turns a photo into a negative: white becomes black, blue becomes orange. It is how you read a scanned film negative, and a quick way to flip a screenshot to a dark version.
- What is the difference between brightness and contrast?
- Brightness moves every tone up or down together, so the whole picture gets lighter or darker. Contrast pushes light and dark tones apart, which adds punch — or, in the negative direction, flattens the image into a soft, hazy look.
- What does Auto levels do?
- It measures each color channel of your photo, ignores the extreme 0.4% at each end, and stretches what is left across the full range. Washed-out, hazy or underexposed shots usually snap back to life with a single click.
- Can I adjust many photos at once?
- Yes. Drop in as many images as you like — the settings apply to all of them, and you can download the results individually or together as a single ZIP.
- Will adjusting reduce quality?
- The adjustment itself works at full resolution with no downscaling. Only the re-encode matters: choose PNG for a lossless result, or keep JPG/WebP at a high quality setting.
