Click a colour in your image and replace it with another — or make it transparent — with tolerance and feathering, on your device.
Recoloured on your device — nothing is uploaded

Runs in your browser. Files are never uploaded — you can go offline after the page loads.
How to use the Replace Colour in Image
Drop an image — the editor opens automatically.
Click the colour you want to change, pick a replacement.
Tune tolerance, then download PNG (or JPG).
Easy to use
Drop files, pick options, download. Whole folders at once, no signup, no daily limit.
Best quality
The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.
Private & secure
Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.
Swap one colour for another — or remove it
Click any colour in your image to target it, then choose what to replace it with. Tolerance decides how close a
pixel has to be to also change, and soft edges feather the boundary so the result doesn't look cut out with
scissors. Tick "make transparent" to knock a flat background out instead of recolouring it.
It all runs on a canvas in your browser — nothing is uploaded. For a photographic subject on a busy background, the
background remover is the better tool; for recolouring vector art, use the
SVG colour changer.
Frequently asked questions
How do I pick the colour to replace?
Click anywhere on the image in the preview to sample that pixel as the target, or set it with the colour picker. Tolerance controls how close a pixel must be to also change.
Can I make a background transparent?
Yes — tick “make transparent” and the matched colour is knocked out; download as PNG to keep the transparency.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
