Place your signature visually

Choose a PDF, draw a signature or upload a clear image, and select Place signature. Drag the signature to the signing line. Use the blue corner or size slider to resize it. Switch pages to add more placements; select a placement to remove it.

Keep the ink, remove the paper

White backgrounds are removed and the signature is cropped to the visible ink. Download a transparent PNG for reuse. Start with dark ink on clean white paper; shadows or colored paper may need a clearer photo.

Review before sharing

Open the downloaded PDF and check every page you signed. This tool places a visible image; it does not create a cryptographic digital signature or prove the signer’s identity. Editing an already digitally signed document can invalidate its prior signature.

A practical document check

Use dark ink on clean white paper or draw in the workspace. Place the transparent signature on the selected page, then drag and resize it onto the signing line.

Limits to account for

Poor lighting can leave shadows after background removal. A visible signature image is not a cryptographic digital signature or identity verification.

Verify the downloaded copy

Open every signed page in the downloaded PDF. Check that the signature covers neither a date nor nearby text, and that it is not stretched.

For another worked-through workflow, read verify pdf before sharing. See the file handling and retention details before uploading sensitive documents.
