The model comes to the picture
Most background removers work by receiving your photo: it is uploaded, cut out on a server, and a result is sent back — often a small one, with the full-size file behind a credit. This site works the other way round. The first time you cut something out, the page downloads a segmentation model into your browser, and from then on every picture is processed on your own machine, on its graphics card where the browser allows it and on the processor where it does not.
Three things follow from that, and they are the whole case for the site. The file is full size, because there is nothing to charge for. Nothing is retained, because nothing is received. And after the first run the model is already on your machine, so the next picture starts at once.

After the cut, what goes behind
A cut-out is half a job. The other half is what the subject should stand on, and this is where the site differs from a remover with a colour picker bolted on. Behind any cut-out you can put nothing (a transparent PNG), a flat colour, the photograph’s own background softened, another picture of yours, or a background drawn by this site’s generator — a gradient, a lit field, a mesh or a grain surface, rendered at the photograph’s exact pixel size rather than stretched from a stock file.
The edge between the two is cleaned rather than just cut. Where the model leaves partial transparency — hair, fur, a soft shoulder — the colour of the old background is estimated from its surroundings and taken out of those pixels, so a subject shot against green does not carry a green rim onto a white page.
What a browser model cannot do
- Glass, water and anything else you can see through. The model decides what is subject and what is not; it has no idea that a wine glass should be ninety percent transparent, so it will keep the glass solid or drop it. The brush can fix the outline, but not give glass back its transparency.
- A subject the same colour as the wall behind it. White sleeves on a white wall, a black cat on a black sofa — the edge is guessed rather than seen. Use the object model, then the smart-edge brush along the boundary.
- Very large pictures on a phone. The matte is computed on a copy about 1400 pixels across and brought up to full size for the file, which keeps phones responsive; on a 50-megapixel photo the finest hair is softer than a desktop editor at 100% would draw it.
Questions before the first picture
Is it free, and is the download full size?
Where does my picture go?
Why does the first cut-out take longer?
remove.bg is closing. Does this do the same job?
Which pictures does it get wrong?
Pictures you open and backgrounds you draw never leave this page. They are cut out and drawn by your browser, and the file is written straight to your disk.
