Background Remover
Cut the background out of a photo and get a transparent PNG. An AI model runs entirely in your browser — your image is never uploaded.
Background removal runs in your browser — your image is never uploaded.
How it works
This tool runs U²-Net, an open-source salient-object-detection network, compiled to run in your browser through ONNX Runtime Web and WebAssembly. When you click Remove background, the model file is fetched once from a CDN and cached. Your image is then resized and fed to the network locally — it is never sent over the network — which returns a map of how likely each pixel is to be part of the main subject. That map becomes the transparency (alpha) channel of a PNG: subject kept, background made see-through. Because the heavy model loads only when you actually run it, the rest of the site stays fast.
How to remove the background from an image
- Drop a JPG, PNG or WebP image, or click to choose one.
- Click Remove background and wait for the progress bar to finish.
- Check the cut-out on the checkerboard preview.
- Download the transparent PNG.
Get the best results
The model separates a clear foreground subject from its background, so it shines on portraits, products, pets and objects that stand apart from what is behind them. High contrast between subject and background, even lighting and a sharp focus all help. The hardest cases are wispy hair, fur, transparent glass, reflections, motion blur and backgrounds that are a similar colour to the subject — there you may see soft or jagged edges. If an edge needs tidying, or you only want part of the frame, trim first with the crop tool, then remove the background. For round avatars, pair the result with circle crop.
Why remove backgrounds in your browser
Product shots, profile pictures and design cut-outs are exactly the images you may not want to hand to an unknown server, and many free background removers upload your file, watermark the result or cap the resolution. Here the work happens in your own browser tab: there is no upload wait, no watermark and no third party touching your photo. The honest trade-off is the first-run download — roughly 5 MB for the AI model, fetched once and then cached, after which the tool is quick and works offline. The privacy guarantee, that your image is not uploaded, holds on every run. Very large photos take longer because the network has more pixels to weigh, so give it a moment on big files.

Frequently asked questions
Is my image uploaded to remove the background?
No. The background is detected by an AI model that runs inside your browser tab using WebAssembly, so the photo itself never leaves your device. The only thing downloaded is the model file, fetched once and then cached; your image stays on your machine the whole time.
Why is the first run slow?
The first time you use the tool, your browser downloads the AI model — about 5 MB. That happens once and is then cached, so later runs start quickly and work offline. The cut-out itself takes a moment because the neural network analyses the whole image to separate subject from background.
What do I get back, and is it transparent?
You get a PNG with a transparent background, so it drops cleanly onto any colour, photo or layout. The preview sits on a checkerboard pattern, which is the standard way to show transparency — the checkers are not part of the file.
What kinds of images work best?
A clear subject that stands out from its surroundings — a person, product, animal or object — gives the cleanest cut. Busy backgrounds, fine strands of hair, glass, motion blur and low contrast between subject and background are harder, so you may see rough edges. The model is general-purpose, so results vary by image.
Can I use the result commercially?
Yes. The tool is free and the AI model it runs is the open-source U²-Net (the lite “u2netp” version), released under the permissive Apache-2.0 licence, which allows commercial use. The transparent PNG you produce is yours to use in products, listings, presentations or designs.
Image Tools removes backgrounds entirely within your browser. Your image is never uploaded. The first run downloads the open-source AI model (about 5 MB), which is then cached for offline use.
