Replace Color
Click a colour, choose its replacement — shading preserved. Recolour products, tweak logos, or knock a colour out to transparency.
The most underrated tool in image editing, done properly
Colour replacement is the quiet workhorse behind a surprising amount of everyday image work: showing a product in five colourways without five photoshoots, matching a logo to a new brand palette, fixing a garment that photographed the wrong shade, or knocking a flat background colour out to transparency. Basic implementations paint every matched pixel one flat colour and the result looks like a sticker. This one preserves shading: each replaced pixel keeps its brightness relative to the colour you picked, so folds, shadows and highlights survive the swap.
How to get a clean swap
- Pick from the midtone. Click a typical area of the colour, not its darkest shadow or brightest highlight — tolerance spreads outward from your pick.
- Tolerance, then softness. Raise tolerance until the whole region is caught, then raise edge softness until the boundary stops looking like a cut line.
- Watch the slider. The before/after comparison updates live — drag it across the edges you care about before downloading.
- Going transparent? Save as PNG; JPG will fill the holes with white.
The replacement runs on a downscaled live preview for instant feedback, then re-runs on every original pixel at export, so the file you download is full resolution. And the photo itself never uploads — colour math happens entirely in your browser's canvas, which is why there's no file-size limit and no per-image fee here.
Common questions
Can I replace several colours?
One pass handles one colour family. Download the result and run it again for the next colour — each pass is a few seconds.
Why does some of the wrong area change too?
The match is purely colour-based, so a blue sky and blue shirt both match blue. Lower the tolerance, or crop first and recombine with the collage maker.
