A typed signature is different from a certificate-backed digital signature

Ask what the recipient accepts
Check whether the form accepts a drawn mark, signature image, a wet-ink scan, or a certificate-backed signature. Those requirements are not interchangeable. Follow the recipient’s stated process for important legal or official documents.
Understand the visible mark
PaperLumo Sign PDF adds a drawn, typed or image signature as visible page content. It does not issue a digital certificate, verify the signer’s identity, create an audit trail, or prove that a person consented to the document.
Place and review carefully
Use only your own signature or one you are authorized to apply. Check the page, size and position before saving. Inspect the exported PDF so the mark does not obscure required text or land on the wrong page.
Preserve signed originals
Editing a PDF can invalidate an existing certificate-backed signature. Keep the original and use the official signing service when that is required. This guide explains tool behavior and is not a legal opinion about enforceability.
