Remove the background from a signature
Turn a photo or scan of your signature into a clean transparent PNG you can drop onto any document, with the paper removed and the ink left crisp.

Why a transparent signature matters
A photographed signature carries the paper with it — a grey or yellowish rectangle that looks obviously pasted on when placed over a document. Removing the background leaves only the ink, so the signature sits on the page as though it were signed there.
Getting the cleanest capture
Sign in dark ink on plain white paper and photograph it straight on in even daylight, avoiding any shadow falling across the page. A flat, evenly lit capture separates far more cleanly than one photographed at an angle under a lamp.
Getting a usable result on thin ink
Ballpoint and pencil signatures are the hardest case, because the strokes are pale and thin enough that an automatic cutout can drop them entirely. Sign again in a fine black felt-tip if you can, photograph it larger than you need, and shrink the PNG afterwards — detail survives downscaling far better than it survives being recovered.
Frequently asked questions
How do I add my signature to a PDF afterwards?
Save the transparent PNG produced here, then place it into your document using your PDF editor or word processor and position it over the signature line. Because the background is transparent, the document shows through around the ink.
The edges of my signature look rough. How do I fix that?
Rough edges usually come from a low-contrast capture rather than the cutout itself. Photograph the page in even daylight with no shadow across it, straight on rather than at an angle, and crop tightly to the signature before you start — that gives the AI far less to guess at.
The ink looks faint after removal — what can I do?
That usually means the original photo was low contrast. Re-photograph the signature in brighter, even light using a darker pen, which gives the model a much stronger edge to work from.
