How to use the Background Remover

  1. Drop a photo on the box, choose one, or paste it.
  2. Click Remove background.
  3. If some background remains, raise the sensitivity; if the subject is being eaten into, lower it. Adjust edge softness to smooth the outline.
  4. Keep it transparent or choose a background colour, then download.

How does this background remover work?

It finds the background by starting at the edges of the image and spreading inwards through pixels that are similar in colour, stopping where the colour changes at the subject’s outline. Everything it reaches becomes transparent. It is designed for plain backgrounds; it is not an AI cut-out tool for busy scenes.

How it works

The tool samples the colours along the image’s border to learn what the background looks like, then performs a flood fill from the edges, accepting pixels whose colour is within the sensitivity you set. Holes inside the subject that are not connected to the edge are left alone, which protects white shirts and highlights.

Edge softness blends the boundary over a few pixels so the cut-out does not look jagged when placed on a new background.

Useful for

  • Product photos on a white or coloured backdrop
  • Logos and signatures scanned on paper
  • Headshots against a plain wall
  • Graphics that need a transparent background

Limitations

  • Busy, patterned or similar-coloured backgrounds will not separate cleanly.
  • Hair and fur on a background of a similar colour may be partly removed or partly kept.
  • Background areas fully enclosed by the subject (for example, inside a cup handle) are kept unless they touch the edge.
  • Images are processed at up to 2,500 pixels on the longest side to keep the tool responsive.

Questions

Why is some of the background still there?
The background probably changes colour, for example a shadow or gradient. Raise the sensitivity a little at a time until it disappears.
Which format keeps the transparency?
PNG. The download is a PNG when the background is transparent. If you choose a solid colour, you can also save as JPG.
