Remove White Background from Image

Where white backgrounds come from

White backdrops are everywhere. Product photographers shoot on white sweeps, scanners turn paper into a white rectangle, and screenshots and brand graphics are often exported on white. Removing that white is usually the first step before putting the subject on a coloured banner, a mockup or a marketplace listing with a different look.

Why AI segmentation beats magic-wand selection

The classic way to remove white is a threshold: select every pixel close to pure white and delete it. That works on a flat logo, but it fails on real photos. Soft shadows are grey, not white, so they stay behind as a dirty halo. And anything white inside the subject, such as a shirt, a cup or a highlight in an eye, gets punched out along with the background.

The model used here, BiRefNet, runs on Cloudflare and decides what is subject and what is background from the shape and context of the whole image. A white sneaker on a white floor keeps its white. A shadow underneath is treated as part of the scene rather than a stray blob of grey.

• White-on-white edges are handled by shape, not by colour distance.
• Soft shadows are not mistaken for the subject.
• Fine detail such as hair and fabric edges stays soft instead of jagged.
• Images up to 20 MB and 4096 px on the long side keep their full size.

Tips for cleaner results on white

1. Use the original file rather than a screenshot of it. Compression artifacts around edges make cutting harder.
2. If the subject is mostly white, a light, even shot helps the model see the outline.
3. Zoom in on the preview at the edges after processing. Subtle halos are easier to spot when enlarged.
4. For a flat white graphic with crisp edges, the result is usually clean, but check the corners and thin lines.

Privacy and limits

Your image is sent over an encrypted connection to the site's server, the white background is removed, and the result returns straight to you. Images are not saved or kept, and location and camera metadata are removed from the copy that is sent. Each visitor gets a free daily allowance of 30 images.

When your goal is a PNG for a design, see remove background from PNG. When you are cutting the subject out to reuse it, the photo cutout page covers composing the result into collages and thumbnails.
