Remove Background — Free, In Your Browser

Remove a photo’s background with a real AI segmentation model (ISNet) that runs in your browser — transparent PNG out, or your subject placed on white or a colour you pick. remove.bg gives free users a 0.25 MP preview and charges about $0.225 per full-resolution image; here the full-resolution result is free, because the model comes to your photo instead of your photo going to a server.

No upload · No sign-up · No file-size cap · Works offline after first load

How to remove the background from a photo with OnyxPDF

  1. Drop a photo into the tool.
  2. On first use only, the AI model (~85 MB) downloads to your device — watch the progress bar; afterwards it is cached and works offline.
  3. Choose the result background: transparent, white, or a custom colour.
  4. Click “Remove Background”, wait while your device runs the model, and download the PNG.

Why do it in your browser instead of uploading?

Good to know (honest limits)

Frequently asked questions

How can background removal work without uploading my photo?

The AI model (ISNet, about 85 MB with its engine) is downloaded to your browser once and cached; inference runs locally as WebAssembly. Your photo itself is never sent anywhere — open the Network tab and check.

How does the quality compare to remove.bg?

For clear subjects — people, products, pets — results are genuinely good. remove.bg keeps an edge on very fine hair and complex edges, and it is faster (server GPUs). In exchange, this is free at full resolution and completely private.

Why is the first use slow to start?

The ~85 MB model must download once. After that it is cached on your device, later runs start immediately, and the tool even works offline.

Can I put the subject on a white or coloured background?

Yes. Choose White or Custom colour in the tool and the result is composited onto that background instead of transparency — handy for Amazon/eBay-style listing photos.
