FAQ
Does this use AI?
No. This is a simple browser canvas tool. It detects white and near-white pixels and makes them transparent.
Is this a person or object background remover?
No. It is not designed for people, hair, pets, landscapes, or complex photos. It works best on flat white backgrounds.
Are my images uploaded?
No. The image is decoded and processed in your browser. It is not uploaded to the LocalMini server.
Why is the output always PNG?
PNG supports transparency, so the processed image is exported as a transparent PNG.
What does tolerance do?
Tolerance controls how far a pixel can be from pure white and still become transparent. Higher values remove more near-white pixels.
