Pull a clean signature out of a signed paper as a transparent PNG.
Sign a piece of paper, photograph it, and DocPrism lifts the signature off the page — background removed, ink color preserved, delivered as a transparent PNG you can drop onto any PDF, Word document or email. Printed text and specks around the signature are filtered out automatically.
The signature ink is separated from the paper and surrounding text — you get just the signature, tightly cropped.
Blue ink stays blue, black stays black — the natural look of your real signature is kept.
The PNG has a fully transparent background, ready to place on any document without a white box.
Insert the PNG into PDFs, Word documents, email signatures or our PDF editor to sign digitally.
Sign with a dark pen on plain white paper, photograph it straight-on in good light, and keep other writing away from the signature.
Yes — the extracted signature keeps its original ink color with a transparent background.
Yes. Download the PNG and place it in any PDF editor — including the free DocPrism PDF editor.
No — files are processed and automatically deleted. Nothing is kept on the server.
