Mix red, green and blue image channels

Suited to photographers and advanced editors who need more control than a single tint when correcting or styling an image.

Tune red, green and blue independently to reshape color balance, correct a cast or build a distinctive grading result with precise control.

How to use

Load a PNG, JPEG or WebP image up to 20 MB to begin mixing its color channels.
Adjust the red channel to increase or reduce the amount of red in the picture.
Do the same for green and then for blue, checking the preview after each change.
Compare the result with the original colors and refine the three values until the look is right.
Run the processing step, then download the corrected image or clear it to start again.

Example

To reduce a blue cast in an indoor photo, lower the blue channel slightly and balance it with red or green. Move in small amounts because every channel affects skin tones, shadows and overall color. The preview helps you judge the shift before saving the file.

Limits and formats

The controls affect the whole image; they do not select one colored object or a brushed area.
Strong changes can introduce the opposite color cast or make neutral areas look unnatural.
The source file must match the accepted formats and remain within the displayed size limit.

Where processing happens

The channel mix is calculated in your browser. The image is read from your device, processed locally in memory, and then offered as a download. Nothing is sent away, and the original file is not stored by the page after processing.

Frequently asked questions

Why adjust red, green and blue separately?

Each channel carries one color component. Changing them independently lets you correct a color cast, warm up a scene or create a more stylized grade than a single global color control would allow.

Does this replace a white balance tool?

It can help reduce a general tint, but it does not automatically measure a neutral reference. You still need to judge the result visually, especially on gray, white or skin tones where errors are easy to see.

Can I restore the original channel values?

Yes, you can set red, green and blue back to their starting values or reload the image. Since the source file remains untouched, you can test several balances without losing the original version.
