A practical guide

How to use Sign PDF

  1. Choose a PDF and the page to sign.

  2. Type a signature or draw one in the page preview, then adjust its position and size.

  3. Save the PDF and review the signature placement.

A visual signature

Sign PDF adds a visible signature mark to a page. It is not a certificate-backed cryptographic digital signature and does not verify the signer’s identity or document integrity. The mark is drawn over the page content.

Processing and limits

Signing runs in your browser. PDFs can be up to 100 MB and 2,000 pages; the workspace displays page previews for up to 48 pages.
