Remove a Solid Background Colour
Click the background and it turns transparent. Works best on plain backgrounds: logos, signatures, and products photographed on white or a single colour.

What this tool does, and what it doesn't
It removes a colour you choose. Click the background and every connected pixel of that colour, within the tolerance you set, becomes transparent. It does not recognise people or objects, so it is best on plain backgrounds rather than busy photographs.
With "Connected area only" ticked, which is the default, only the area joined to your click is removed. A white logo on a white page keeps its white letters inside the shapes that aren't touching the background. Untick it when the same colour shows through gaps, for example inside the loops of handwriting.
Getting clean edges
Edges are rarely one exact colour. Scanned signatures and product shots have soft, slightly shaded borders, so a low tolerance can leave a thin halo. Raise the tolerance a step at a time and click again until the halo disappears, but stop before parts of the subject start to vanish.
For the cleanest result, start with a good source: a signature in dark ink on plain white paper, or a product on a sheet of card with even lighting. If you need to cut a person out of an ordinary photo, a tool that detects subjects will do better than colour removal.
