Remove Background
ProCut the subject out of any photo — then fine-tune the edge, pick a background and save it as PNG, WebP or JPG.
How it works
- 1
Upload a JPG, PNG or WebP photo (large photos are shrunk in your browser first, so they upload faster).
- 2
Documateo's AI model detects the subject and separates it from the background on our servers.
- 3
Fine-tune in your browser: clean up the edge, trim the empty space, and choose transparent, white, black, a colour or a blurred copy of your photo as the background.
- 4
Download as PNG, WebP or JPG at full size, 2048 px or 1080 px.
Remove Background — frequently asked questions
- What kind of photos does this work best on?
- Photos with a clear, well-defined subject — people, products, animals — with reasonable contrast against the background get the cleanest edges. Very fine detail like loose hair strands or transparent objects (glass, smoke) are inherently harder for any background-removal AI to isolate perfectly.
- There's a light or dark outline around my subject. How do I remove it?
- Raise 'Clean edge' by 1–2 px in the editor to pull the edge inward, and add a little 'Soften edge' if it looks too sharp. These adjustments run in your browser, so you can try them as often as you like without re-running the AI.
- Which format should I save in?
- PNG keeps the transparent area at full quality. WebP also keeps transparency and is usually smaller. JPG can't hold transparency, so it is available once you choose a background such as white, a colour or the blurred photo.
- Does the editing use up more credits?
- No. Only the first step, cutting the subject out, runs on our servers and uses a credit. Everything after that — edge clean-up, trimming, backgrounds, format and size — happens on your device and is unlimited.
- Why does this need AI instead of running locally like other tools?
- Identifying which pixels are 'subject' versus 'background' in an arbitrary photo requires a trained image-segmentation model, which needs real compute to run — this isn't something a browser can do on its own.
