AI Background Remover Image
Cut a subject out of any background with a real segmentation model — running on your own device, not a server.
AI Background Remover is a free online tool that cut a subject out of any background with a real segmentation model — running on your own device, not a server. It runs entirely in your web browser using Canvas 2D, so files are processed on your own device and never uploaded to a server. There is no sign-up, no file size limit imposed by the site, no watermark and no paid tier.

About AI Background Remover
Every other background remover uploads your photo. remove.bg, Photoroom, Canva, Adobe — all of them send the file to a server, run a segmentation model there, and send a cutout back. This runs the same class of model, an ONNX segmentation network, on your own device. The picture never moves; the model comes to it instead. That inversion is the whole point, and it is not something a service built on server inference can copy without rebuilding itself.

Questions
Why is there a 62MB download?
Because that is the model and the runtime that would otherwise live on somebody else’s server. It is fetched once from this site, cached by your browser, and never fetched from a third party — so using this tool does not tell anyone else that you used it. The same approach powers the OCR tool, which self-hosts 11MB of Tesseract.
Why is it slower than remove.bg?
Because they have a GPU and you have a browser tab. A server answers in well under a second; this takes several seconds per image on a typical laptop CPU, plus a one-off wait the first time while the model arrives and compiles. That is the honest trade, and it is the only cost — the result quality is from the same family of model.
What is it good at, and bad at?
It is a general subject-segmentation model, so people, products, animals and objects with a reasonably defined edge all work well. Fine hair, motion blur, glass and near-identical foreground and background colors are where any model of this size struggles. For a flat, solid-color backdrop the older color-key Background Remover is faster and often cleaner.
Does it work offline?
Once the model is cached, yes. Load the tool, run it once on any image, then disconnect — it keeps working. That is worth testing if you want to confirm the no-upload claim for yourself; a tool that works with the network off cannot be sending your file anywhere.
Which model is it?
An ISNet-family segmentation network in quantized ONNX form, executed through ONNX Runtime Web. The quantized build is 42MB against 84MB for the higher-precision one; doubling a first-use download for a modest quality gain is a poor trade on a free tool.
