Remove Background from Image

It is built for photos of people

The on-device model is a portrait segmentation model, which means it is genuinely good at people and does not recognise anything else. Headshots, full-body shots, group photos and selfies work well. A dog, a product on a table or a screenshot will find no subject at all — and when that happens the tool says so rather than quietly handing you a bad cutout.

In that case it falls back to colour detection, which removes background by colour similarity starting from the edges of the frame. That works when the background is reasonably even — a product against a plain white sheet, a logo on a flat colour — and struggles when it is busy. Knowing which of the two produced your result matters, so the tool tells you underneath the preview every time.

One slider, and what it actually does

After an automatic cutout the slider is labelled Edge tightness and moves the cut point of the detected mask between 35% and 85%, starting at 60%. Raise it to bite further in and clear background colour still clinging to the outline; lower it to keep more of the soft edges, which matters for hair. It refines the detection — it never switches it off. When colour detection was used instead, the same slider becomes Colour tolerance and controls how far the fill spreads.

You can see the result before you download

The original and the cutout sit side by side, with the transparent areas shown over a checkerboard so you can actually see what has been removed rather than guessing against a white page. The download is a PNG, because transparency cannot survive in a JPG.

What it will not do perfectly

Fine hair against a busy background is hard for any browser-based tool, and this one is no exception — the paid services that handle it well run much larger models on their own servers. Expect a clean cutout on a clear subject and expect to nudge the slider on a difficult one.

Blur Image Background keeps the original background but throws it out of focus, and Profile Photo Maker crops a finished cutout to the square and circular sizes profile pictures need.
