A signature photographed on white paper is not transparent — dropped into a PDF it arrives as a grey or cream rectangle over the text underneath. Removing the background turns the ink into an object with nothing behind it, so it can sit on a contract, a letterhead or an invoice the way a real signature does. Two things decide whether the result looks like ink or like a cut-out: light and contrast. Photograph the page in even daylight without a shadow falling across it, and use a pen that is genuinely darker than the paper — a fine grey ballpoint on cream paper gives the model very little to separate. If the edges come out soft, re-take the photo rather than accepting it; there is no repair for detail that was never in the image. Keep the background transparent for documents. A white background looks identical on a white page and wrong on everything else.
No. The model runs in your browser and the image never leaves the device, which matters more here than for most images — a signature is a legal mark.
The model keeps what it is confident is foreground. Pale ink on white paper leaves it little to work with, so a darker pen and even lighting change the result far more than any setting does.
Transparent, for anything that goes on a document. A white background is invisible on white paper and shows as a rectangle on any other colour.
A PNG. It is the common format that stores transparency — a JPG cannot, which is why signatures exported as JPG always arrive with a white box.
