FAQ
About the Background remover
Is my image uploaded to a server?
No. Reading, processing and PNG export all happen in your current browser.
Is this an AI background remover?
No. It estimates transparency from a selected screen color, so it works best with uniform green, blue, white or similar backgrounds.
Why is the result exported as PNG?
PNG supports transparency while JPG does not.
