PaintBox

Free tool

Remove a background. Free, no sign-up.

Drop a photo and get the subject on a transparent background, ready for a product page, a sticker or a slide. Unlimited, no account, no watermark.

Your image never leaves your computer. The model runs in your browser.

How it works

  1. Drop a photo. Drop a photo of a person, product or pet on the page, or choose one.
  2. Let the model cut it out. A small open-source segmentation model (U-2-Netp, Apache-2.0) runs in your browser. It downloads once, about 4.6 MB, and is cached.
  3. Download the PNG. Save the cut-out as a transparent PNG, or keep editing it in PaintBox.

Edges need a touch-up, or the subject needs a new backdrop? Open PaintBox, where the same model cuts a layer mask you can paint on, so nothing is thrown away.

Agents: the same cut is the remove_background and make_cutout tools on the PaintBox MCP server, as a reviewable proposal on a document. See PaintBox for agents.
