Background Changer
Cut out the subject with on-device AI and put it on a colour, gradient, blur or photo.
About this tool
Drop a photo, press cut out, choose a background: pure white for a listing, a brand colour, a soft gradient, the original blurred, or a photo of your own. The subject is found by the same model as the background remover, running in your browser.
Where a new background earns its keep
Marketplaces want products on white (Amazon requires it), a LinkedIn headshot reads better on a plain tone than a kitchen, passport and visa photos need a uniform light background, and a “portrait mode” blur rescues a snapshot taken against clutter. All of those are a cutout plus a fill, and the cutout is the hard part: U²-Net lite, a 4.6 MB segmentation network served from this site, with its runtime (about 10 MB, ONNX Runtime) fetched from the jsDelivr CDN the first time you press the button and cached after — the same arrangement as the background remover, and the photo itself never leaves your device. Honest limits: fine hair, glass, smoke and motion blur produce soft or ragged edges (the softness slider hides most of it), and a subject the same colour as its surroundings can be partly missed. For a transparent PNG to use elsewhere, the remover; for the strict passport crop and size, the ID photo tool; compress the result for the web.
Frequently asked questions
Is my photo uploaded?
No — the model file comes from this site and its runtime from a CDN, both once; the cutout and the new background are computed in your browser. Nothing about the photo is sent anywhere.
Can I use my own background photo?
Yes — choose ‘Your photo’ and pick an image; it is scaled to cover the frame. Blur it first with the image blur tool if you want the subject to stand out.
Why are the edges rough around hair?
Segmentation networks find regions, not individual strands. Increase the edge softness, or use a plain background close to the original’s tone so the edge is less visible.
Does it work for product photos?
Well, on a clear single object — that is the model’s easiest case. Marketplaces usually require pure white: pick Colour and leave it at #ffffff, then download as JPG.
