Background Remover Guide

Clear a plain background from an image by flooding in from the edges.

Background Remover makes the background of a picture transparent by flooding inward from pixels along the edge and clearing anything close enough in colour. It suits a product shot on a plain surface or a screenshot on a flat colour, not a busy scene.

Cut out a flat-background test image

Choose a disposable image under Image. Leave Colour match at 24%, Start from on Every edge pixel, Edge softness at 1 and Output format on PNG. The status should report the percentage of pixels removed, and Removed in the Result panel shows the same figure. Raise Colour match and more of the background goes; if part of the subject disappears too, lower it again. Try The four corners when only the corners are a reliable sample. Choose Download for a transparent PNG or WebP.

If Nothing matched the background appears, the edges are not one flat colour, so raise the colour match or change the seed pixels. The match is colour-based, not object recognition, so a street, a room or a crowd comes out ragged. Images larger than four megapixels are scaled down to work faster, and Working size says when that happened. JPEG cannot store transparency, which is why the output is PNG or WebP only.

Questions you might have

Will this work on a photo with a busy background?
No, and no colour match can. A street, a room or a crowd needs a segmentation model that understands what a person or an object is. This page is honest about that limit rather than producing a ragged edge that has to be cleaned up by hand.
Why is part of the subject disappearing?
The subject shares a colour with the background and the match is too generous. Lower the colour match until it stops, or start from the four corners when only the edges are reliable.
What happens to the parts that are left?
They keep their colour and position exactly, and the cleared area becomes fully transparent. The download is a PNG or a WebP because JPEG cannot store transparency at all.
