About Background Remover

Background Remover removes the background from any image — directly in your web browser, using an on-device AI model. There's no sign-up, no watermark, and no limit on how many images you process.

How it works

The first time you use the tool, your browser downloads a small AI model (an image-segmentation network called ISNet, tens of megabytes) from IMG.LY's content delivery network. That download contains only the model itself — never any image or file of yours. Once downloaded, the model runs locally using WebAssembly or, where supported, your device's GPU via WebGPU, and every image you process runs against that already-downloaded model, entirely on your own device.

Why is it free?

Because background removal runs in your own browser rather than on a server we operate, there's no per-use processing cost to pass on — the site is instead supported by advertising.

Your photos never leave your device

Every image is decoded, processed, and made available for download entirely inside your browser's own memory. We never receive the file, because it's never sent anywhere — you can verify this yourself by watching your browser's network activity while you use the tool.
