What is Hue & Saturation Adjuster?
Hue & Saturation Adjuster lets you change the color character of any image without a desktop editor. Shift hue to swap color tones globally, raise saturation to make colors more vivid, lower it to desaturate toward grayscale, and adjust lightness to brighten or darken the result.

- Drag the Hue Rotation slider to shift colors across the spectrum.
- Use the Saturation slider to make colors more or less intense.

Frequently Asked Questions
No. All processing happens entirely in your browser using the Canvas API. Your image never leaves your device.
Any format your browser can decode: JPG, PNG, WebP, GIF, AVIF, BMP, and more. The download is always saved as a PNG.
The tool works at the pixel level converting RGB to HSL and back. Small adjustments have minimal quality impact. The output is saved as lossless PNG so there is no additional compression loss.
Hue is the color wheel angle —shifting it changes all colors at once (e.g., red becomes orange or purple). Saturation controls color intensity —higher values make colors more vivid, lower values make them grayer. Lightness shifts the overall brightness of the image toward white or black.
