When does removing a colour work best?
This tool makes every pixel close to the colour you pick fully transparent. It works best on images with a solid, even background — logos, icons, and graphics on a single flat colour. Use the tolerance slider to include anti-aliased edges; photographs with busy or gradient backgrounds need a manual or AI background remover instead.
Why does the result have to be a PNG?
Transparency requires an alpha channel, and PNG supports it (JPG does not). That's why the export is always a PNG — so the removed areas stay see-through wherever you use the file.
Is this tool free and private?
Yes. It's completely free with no signup, and the image is processed entirely on your device — nothing is uploaded.
Frequently asked questions
- Can it remove any background?
- It removes a single solid colour. For photos with detailed or multi-colour backgrounds, a dedicated AI background remover will do better.
- What does the tolerance slider do?
- It widens how close a pixel must be to the chosen colour to be removed, which helps clear soft, anti-aliased edges around the subject.
- Do you upload my image?
- No. Everything happens in your browser — your file is never uploaded, stored, or seen by us.
