Practical guidance

Add a visible signature to a PDF online

Sign PDF lets you draw, type, upload, or temporarily send signature artwork from a phone, then place and resize visible marks on one or more pages. This is an electronic visual-signature workflow, not a certificate-backed digital signature or identity-verification service.

Draw, type, or upload signature artwork

Choose the method that produces a clear mark, then position it carefully inside the correct signature area.

The optional pairing flow transfers temporary signature artwork to the desktop session. The PDF itself remains on the desktop browser.
