How unbg.me removes a background in your browser

Updated

Three steps, all in your browser.

  1. Choose an image. Pick or drop a JPG, PNG or WebP. You can also paste one.
  2. Remove the background. Your device does the work. The image isn't uploaded.
  3. Save your PNG. Keep the background transparent, or pick white or another colour first. Several images download together as a ZIP.

The first time

Before your first image, your browser downloads the background removal engine (about 20 MB on phones and tablets, up to about 142 MB on computers). Computers use a larger, more detailed model. That takes a moment on a slow connection. Your browser usually keeps it, so later images start quickly, but clearing site data or an update can mean downloading it again.

Choose the right background

  • Transparent is best for logos, stickers, presentations and designs where the image sits on top of something else. The PNG keeps full transparency, including soft edges.
  • White suits product listings and catalogues that ask for a clean white background. If a marketplace has exact photo rules, check them: unbg.me changes the background only, not framing or margins.
  • Custom colour lets you match a brand colour or a slide theme. Enter a hex code or use the colour picker.

Commercial use of results hasn't been confirmed yet during the beta. The credits page explains why.

What you download

  • A PNG file named after your original, for example product-shot-unbg.png.
  • The same pixel dimensions as your original, up to 60 megapixels, when your browser reports enough memory. If it doesn't, you get a smaller version and the tool tells you.
  • No watermark and no unbg.me branding in the image.
  • No hidden metadata: camera details and GPS location from the original aren't copied into the result.

Get cleaner cut-outs

Automatic background removal works best when the subject is easy to tell apart from what's behind it.

  • Contrast helps. A dark jacket against a light wall separates better than a grey jacket against grey concrete.
  • Keep the subject whole and in focus. Motion blur and subjects cut off at the edge of the frame make edges less certain.
  • Use the original file. Screenshots and heavily compressed images carry artefacts the model may keep.
  • One main subject gives the most predictable result. Groups of people are usually kept together; mixed objects may not be.

Harder cases for any automatic tool: wispy hair against a busy background, glass and transparent objects, smoke, and shadows you want to keep. Zoom in and check edges before you use a result somewhere important. Edit edges lets you adjust edge hardness and feather and remove colour fringe, one image at a time (in a batch, select Preview / Edit on a finished image).

Limits

  • Still JPG, PNG and WebP up to 50 MB and 60 megapixels. HEIC, SVG and animated images aren't supported; save a HEIC photo as JPG first.
  • Up to 50 images at a time; fewer on phones, on devices with less memory and in browsers that don't report memory, such as Firefox and Safari (20 or 10); the tool shows your limit.
  • On devices with limited memory, very large images may be saved at a smaller size. unbg.me tells you when this happens.
  • Results are automatic. Check fine hair, fur and glass before using the result.

Browsers

Tested with real background removal on desktop Chrome and Firefox on Windows. Edge, Safari and phones are still being tested. If your browser can't run unbg.me, the page tells you instead of failing silently.
