questions

Does it work on photos with busy backgrounds?
No. This is a colour cut, not an AI segmentation. It shines on flat or gently graded backgrounds. For tricky ones, the editor has a wand and an eraser for hand work.
Why is there a halo around the edges?
Anti-aliased edges carry a bit of the old background. Raise the tolerance a little or add a soft edge of 1 to 2 pixels.
Is anything uploaded?
No. The whole tool runs in your browser tab. Files never leave your device.
Is it really private?
Yes. The tool is code that runs in your browser tab. Your PNGs are never sent to a server. Open the network tab and check. Nobody is watching. Goon in peace.

What kind of background this removes

The tool finds the colour that touches the edges of the picture and removes every connected pixel of it, keeping whatever it surrounds. That covers logos on white, icons on a flat colour, sketches on paper, screenshots, product photos on a plain backdrop and rendered graphics. It is a colour cut, not a machine-learning segmentation, so busy photo backgrounds are better handled by hand in the editor with the wand and the eraser.

Tolerance and soft edges

Tolerance decides how far a pixel may differ from the background colour and still go: raise it for gradients and JPG noise, lower it when the subject shares the background’s hue. A soft edge of a pixel or two blends the cut so the result composites cleanly on any colour. The output is always PNG so the transparency survives.
