}Page guide
Correct a color cast using a neutral reference area in your image. Adjust the strength and compare the result.
How to use White balance correction
- Choose a still image.
- Enter the position and size of an area that should be neutral gray.
- Set the correction strength, run the tool and download the corrected PNG.
Useful next steps
Choose a reliable neutral patch
Coordinates begin at the top-left pixel. Use a patch that should be gray, with visible pixels and nonzero values in every color channel. Transparent pixels carry less weight.
Know the correction limits
The tool applies gains to decoded encoded RGB and preserves alpha. It is not a camera-raw or color-managed correction. The report lists gains and pixels whose corrected channels exceed the available range.
