Free Adjust Saturation – how it works
Adjust Saturation lets you change the colour intensity of an image — dragging the slider right makes colours more vivid and punchy, dragging left desaturates towards greyscale. It is the quickest way to correct a washed-out photo, give a faded image more life, or stylise a photo to a muted or black-and-white look without a full photo editor.
The adjustment is applied in real time on the preview canvas using the HSL colour model. The saturation value of every pixel is multiplied by your chosen factor while hue and lightness are preserved, so colours shift in intensity without going off-hue.
No image data is sent anywhere. Processing uses the browser's Canvas API and runs on your device.

How to use Adjust Saturation online
- Upload your image. Drop a JPG, PNG, or WebP image. A live preview updates as you adjust the saturation slider.
- Drag the saturation slider. Move the slider right (above 100%) to increase colour intensity, or left (below 100%) to desaturate. 0% produces a greyscale image.
- Download the adjusted image. Click Apply to encode the result at full resolution, then download it in your chosen format.
When to use it
- Boost the saturation of a washed-out landscape or travel photo to bring colours back to life.
- Desaturate a portrait photo to a muted or greyscale style for a editorial look.
- Increase the vividity of product images before listing them on an e-commerce site.
- Reduce oversaturated colours from a phone camera that applies heavy processing.
Known limitations
- The tool adjusts global saturation uniformly — selective colour adjustments (e.g. only red channel) are not available.
- Extreme saturation boosts can push highly saturated pixels to pure colour with no detail, which is irreversible in the output image.
- For precise colour grading, use a dedicated image editor with LAB or HSL channel controls.
Frequently asked questions
How do I change the saturation of an image online?
Upload the image, drag the saturation slider to the level you want, and download the result. No account or upload to a server is required.
What does increasing saturation do to a photo?
It intensifies all colours, making reds redder, blues bluer, and greens greener. Colours that were muted or grey are unaffected since greyscale pixels have no hue to boost.
How do I make an image greyscale using this tool?
Set the saturation slider to 0%. This removes all colour information and produces a greyscale version of the image.
Is my image uploaded to adjust saturation?
No. The saturation adjustment runs entirely in your browser using the Canvas API. Your image never leaves your device.
