Guide: Free Background Remover

How to remove a background

Drop one or more photos on the page, paste an image, or press Choose images. Then press Remove background. The first time, your browser downloads the AI model (about 58 MB) and keeps it for next time. After a few seconds you see the result next to the original; drag the Before / After slider to compare.

Choose what goes behind the subject

  • Transparent gives a PNG with a real alpha channel, ready for logos, product shots and stickers.
  • Color fills the background with a flat color, for example white for marketplace listings or ID style photos.
  • Blur keeps your original background but blurs it, like a portrait mode.
  • Image places your cut-out on any picture you choose.

Fix the details

Edge refinement snaps the cut-out to the real edges of your photo at full resolution, which helps with hair and fur. Grow / shrink edge moves the border in or out by a few pixels. Use Restore and Erase brushes to paint corrections by hand, zoom with the wheel or pinch, and Undo if you slip.

Batch and download

Add many photos at once. They are processed one after another and you can open any of them to adjust it. Download full size saves the current image at its original resolution. Download all (ZIP) packs every finished image into one file.

Good to know

  • Very large photos can exceed what a phone can handle. The tool then reduces the size a little and tells you.
  • The AI works best when there is a clear main subject. Crowds, glass and thin transparent objects may need brush touch-ups.
  • On browsers that allow it, the AI uses several processor threads to run faster.

FAQ

Is it really free at full resolution?

Yes. The result keeps the exact pixel size of your original photo, there is no watermark, no sign-up and no daily limit. Many other sites show a small preview for free and charge for the full-size file. Here the full-size PNG is the normal download.

Are my photos uploaded anywhere?

No. The AI model is downloaded once to your browser and runs on your own device. Your photos are read by the page and a background worker in your browser and are never sent to a server. Close the tab and they are gone.

Why does the first run download about 58 MB?

The segmentation model that finds the subject is a real neural network. It is downloaded once, saved in your browser cache, and then reused, so later visits start straight away. Clear site data in your browser to remove it.

How fast is it?

On a typical computer one photo takes a few seconds. Phones and older laptops are slower. The model looks at a 512 pixel version of the photo, then the cut-out is refined against the full-resolution picture, so large photos cost about the same AI time as small ones.

The edges are not perfect. What can I do?

Move the Edge refinement slider, or use Grow / shrink edge to trim a halo. For anything the AI got wrong, switch to Restore to paint parts of the subject back, or Erase to remove leftover background. You can zoom in for precise work.

Can I use the results commercially?

The tool and the AI model are released under licences that allow commercial use (MIT). You are responsible for having the rights to the photos you process.
