One click, and the background is gone
Drop a photo of a person, a pet or a product and the background is taken out: the subject stays at full size on a transparent background, ready to place on a slide, a banner or another photo. Choose White for the plain background marketplaces ask for, or any color to match a brand. The slider in the preview compares the result with the original.
Changing the background or the format does not run the model again — the outline it found is kept — so trying white, then blue, then transparent is instant.
How it works, and its limits
The work is done by U²-Net, an open-source neural network trained to find the main object in a picture, running in your browser through ONNX Runtime. It reads a small copy of the photo, marks what is subject and what is background with soft edges, and that outline is applied to your photo at its original size.
It does best with one clear subject that stands out from what is behind it. Hair against a busy background, glass, smoke and several people at once are the hard cases; the detailed setting uses a larger model that gets more of them right. The first photo takes longer because the model is loaded — about 8 MB for fast, 29 MB for detailed — and after that it is kept on your device.
Your photos stay on your device
Most online background removers upload the photo, and the photos people cut out are very often of people. Here nothing is sent anywhere: the model comes from this site once, and the rest happens in this tab. To fit the result to a listing, resize it or crop it next.
Frequently asked questions
How does it know what the subject is?
A segmentation model — U²-Net, an open-source neural network trained to find the main object in a picture — marks every pixel as subject or background, with soft edges in between. It runs in your browser, on your device's processor, which is why the first photo takes a moment and why nothing has to be uploaded.
Fast or detailed?
Fast uses a 4 MB model and takes a few seconds a photo; it handles a person or a product against a plain background well. Detailed downloads a 25 MB model once and takes about twice as long, and it is noticeably better with hair, fabric, thin parts and busy backgrounds. Start with fast and switch if the edges look chewed.
Which format keeps the transparency?
PNG and WebP. JPG has no transparent pixels, so a transparent cut-out saved as JPG gets a white background. For a marketplace product photo, choose White and JPG; for a logo or a sticker to place on something else, keep Transparent and PNG.
Is the photo reduced?
No. The model reads a small copy to find the subject, and that outline is applied to your photo at its original size, so the result has every pixel the original had.
Are my photos uploaded?
No. The model is downloaded from this site the first time and kept on your device; after that the whole job runs in this tab, even offline. Online background removers send your photo — often of people — to their servers; this one never does.
