How a background gets removed
A segmentation model looks at the image and decides, pixel by pixel, what belongs to the main subject and what belongs behind it. That decision comes out as a mask: a greyscale image where white is kept and black is discarded. Applying it to your photo is what produces the transparent PNG you download.
The output is always PNG, because it's the widely supported format that stores transparency without loss. A JPG can't: it has no alpha channel, which is why converting to JPG afterwards fills whatever was left empty here with a colour.
The model looks for one main subject, not every object in the scene. It does very well with portraits, products on a surface and animals; it struggles with glass, smoke, mesh and loose hair against a similar tone, where the line between subject and background genuinely stops existing.
That's what edge softening is for, and why it's adjusted after you've seen the cut: it blurs the cut line by a few pixels so the result doesn't look pasted on. It's also why it's worth checking the result on black and on white before downloading — each backdrop gives away a different flaw.
Common questions
- Can I remove the background from several images at once?
- Not yet: they're processed one at a time. Each image takes an inference slot on the server, which is also why it occasionally asks you to wait a few seconds.
- Why does the result look the same as before?
- Because a transparent background and a white one look identical on a white page. Switch the view to black and you'll see it: the checkerboard and black mark what's actually empty.
- What if it cut out the wrong subject?
- The model picks whatever dominates the scene. If you want something else, crop to that area first and run it again: with less scene around it, the choice stops being ambiguous.
- Does it work for product photos?
- That's the case it handles best, especially with the item centred on a plain background. Tick "crop to the subject" and the PNG comes out already trimmed, with no leftover transparency around it.
- Can I put a different background behind it afterwards?
- Yes. The PNG keeps its transparency, so it drops onto any background in whatever editor you use. If you convert it to JPG here, the colour you pick fills that space instead.
