Background Remover (Color-Based)
Knock out a plain, solid-colour background by making a colour transparent.

Click background colors to remove them
This is a colour-key background remover: it samples a background colour and makes every pixel close to it transparent, then exports a PNG with an alpha channel. It works the same way a video “green screen” does, and it shines on images that already have a plain, evenly lit backdrop. It runs entirely on a canvas in your browser, so your image is never uploaded.
This is not AI — tolerance is the whole game
Unlike subject-detection tools, this one has no idea what your subject is. It only compares colours. The tolerance slider sets how far a pixel's colour can stray from the background colour and still be erased. Too low and patches of background survive; too high and it starts eating into your subject wherever the subject shares tones with the background. The best results come from nudging tolerance until the background just clears without biting into the edges.
When it works well, and when it will not
Expect clean results on a product shot against a solid white sweep or a logo on a flat colour. Expect a struggle with busy or gradient backgrounds, soft shadows, motion blur, and fine wispy edges like loose hair, because those pixels blend the subject and background into in-between colours the key cannot cleanly separate. If your background is complex or the subject is intricate, an AI subject-cutout tool will do better; this tool is the fast, private option for simple, flat backdrops.
Frequently Asked Questions
Does this use AI to detect the subject?
No. It removes pixels by colour similarity to the background — like a green screen. It has no concept of your subject, which is why a plain, even backdrop matters.
What does the tolerance slider do?
It sets how close a pixel must be to the background colour to be erased. Raise it if background patches remain; lower it if the tool starts removing parts of your subject.
Why are the edges or hair messy?
Edge and hair pixels blend subject and background into intermediate colours the colour key cannot cleanly split. Busy or gradient backgrounds cause the same problem; a flat backdrop works best.
What format is the result, and is it uploaded?
The result is a PNG with transparency, generated on a canvas in your browser. Nothing is uploaded.
