About this tool
Finds the subject in a photograph and throws everything else away, leaving a transparent PNG you can drop onto any colour or any other picture. The model that does the finding runs inside this tab, on your own processor, which is why there is a one-off download the first time and nothing at all after that.
How to use it
- 1Drop in a photo, or paste one straight from the clipboard.
- 2Leave the quality on Standard unless the edges matter more than the wait.
- 3Press Remove background and give it a moment.
- 4Check the result against the chequerboard, which is how transparency is drawn.
- 5Download the PNG.
Good to know
Two models, and why you get a choice
Standard is U-2-Net's small variant: 4.4 MB, and it finished in about two tenths of a second in testing. Best edges is BiRefNet lite, 78 MB to fetch and twenty to thirty seconds per picture, during which the page stops responding. Running it on the graphics card was tried and had to be abandoned; it produced no error, just a quietly wrong cut-out. On a person against a plain wall the two models are hard to tell apart, so the small one is the default and the large one is never fetched unless you ask for it. The file is read into memory by your own browser and processed there, so it is never uploaded and never reaches a server.
The mask is sharpened against your picture
The small model looks at a 320 pixel square, so its answer is about a tenth of the width of a modern photo and its edges arrive soft. Rather than simply enlarging that, the outline is guided back onto the real edges in the full-size image, which recovers individual strands of hair and fur that a plain enlargement smears into a grey band. The cut-out is always saved at the resolution you supplied, never at the model's.
Always a PNG
There is no format choice here because there is only one sensible answer. JPEG has no transparency at all and would hand back your subject on a white rectangle, which is the thing you came here to remove. PNG keeps a full alpha channel, so the soft edges stay soft.
The licences are the reason for the model choice
Almost every browser background remover uses a model published for non-commercial use only. The two here are Apache-2.0 and MIT, which is what makes them usable on a site that carries advertising, and is why the results differ a little from tools you may have tried elsewhere.
