How to use
Enter the source and replacement colors. Tolerance is Euclidean distance in 8-bit RGB.
Limits and behavior
Matching is global across the image. Replacement alpha multiplies existing alpha; source target alpha is ignored. Still PNG, JPEG and WebP only; 20 MB, 4 megapixels and 4,096 pixels per side. Processing stays on your device. Exports apply orientation and discard source metadata. PNG output preserves transparency unless the selected operation composites it.
Change matching colors in a picture
Choose an original color and replacement color to recolor pixels within the supported tolerance.
Will every similar-looking color be replaced perfectly?
No. Shading, compression artifacts and color distances can affect which pixels are selected.
