Know the limits

Local does not mean unlimited.

Browser processing protects the file from an upload workflow, but the browser, device, output format, and selected settings still matter.

  • The Apache-licensed MODNet model is optimized for people and portrait-style subjects; complex products, transparent objects, fine wires, and similar foreground/background colors can produce imperfect edges.
  • The first model download is about 7 MB plus the local inference runtime and is cached by the browser.
  • Always inspect hair, reflective edges, and small details before publishing.

Clear answers

Background remover questions.

Is the photo uploaded for AI processing?

No. The model and inference runtime load as static NullKit assets, and processing occurs on this device.

Does it work for every product?

No. This first model is strongest on people and portrait-like compositions. Difficult transparent, reflective, or very thin objects may need a specialist editor.

Why is the first run slower?

The browser must download and initialize the local model and inference runtime. Compatible browsers cache those static files for later runs.
