What a PDF Digital Signature Is

A PDF digital signature lets someone sign a document online instead of using pen and paper, like placing a name and time stamp that cannot be changed. It proves who signed and when, and the platform locks the file so edits are visible. In signNow, you upload a PDF, add signature and data fields, configure signer order and authentication, then send the document to recipients who eSign from a browser or mobile device. The platform stores an immutable audit trail and secures the document with modern encryption and access controls.

PDF eSignature FAQs and Fixes

Common questions and practical troubleshooting steps for PDF signing issues encountered in signNow, aimed at administrators and everyday users.

• Why can’t a recipient sign the PDF?
  Confirm the recipient has the correct email address, check for required fields left empty, and ensure the signing link has not expired. If email delivery failed, resend the request or generate a new signing link from the document page.
• How to add missing fields after sending?
  If changes are needed after sending, void the current document and create a new version with corrected fields, then resend. Active sign requests cannot be modified without reissuing due to audit integrity.
• What if a signer loses their access link?
  Use the document’s Manage page to resend a new link or copy a direct signing link. For security, consider enabling SMS authentication to verify identity upon re-entry.
• Why is a signed PDF not accepted by a counterparty?
  Confirm the counterparty’s acceptance standards; provide the audit trail and signature certificate from signNow to validate authenticity and chain-of-custody evidence.
• How to troubleshoot mobile signing issues?
  Advise signers to update the signNow app or use a modern mobile browser. Clear browser cache or reinstall the app if rendering problems persist on specific PDF elements.
• Who to contact for enterprise API errors?
  Provide the API request ID and timestamps, then consult signNow support with account admin privileges enabled to troubleshoot authentication, rate limits, or payload issues.
