Background Remover

The edge is flooded from the pixels you choose and everything close enough in colour is made transparent. That works well on a plain or studio background and poorly on a busy one, which needs a real segmentation model rather than a colour match. Images larger than 4 megapixels are scaled down to fit.

About this tool

Make the background of a photo transparent. Pixels along the edge are flooded inwards and everything close enough in colour goes, which turns a product shot on a plain surface or a screenshot on a flat colour into a cut-out PNG in one step.

Questions

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.
