FAQs About how to add my digital signature in PDF

Common issues and answers for adding a digital signature in a PDF with signNow, covering access, signature appearance, authentication, and audit records.

• I cannot place the signature field
  Ensure the PDF is unlocked and not a secured form; use the signNow editor Fields tab to drag and drop a Signature field. If the document is a flattened scanned image, run OCR or upload a searchable PDF for reliable field placement.
• Signature looks different on recipient device
  Signature rendering varies by viewer; use signNow’s saved signature or typed signature to ensure consistent appearance. Advise recipients to open the signed PDF in a modern PDF viewer or the signNow app for accurate display and validation.
• I did not receive the signing invite
  Check spam and verify the recipient email address; resend the invite from the signNow document page and confirm domain allowlists in corporate email settings if needed.
• How to verify a completed signature
  Open the signed document and review the Audit Trail for signer identity, timestamps, and IP addresses. The audit record shows each action and verifies the document's execution history.
• Can I sign offline on mobile
  Yes. Use the signNow mobile app to download the document for offline signing; the app synchronizes and uploads signed PDFs automatically when it reconnects to the internet.
• What if a signer needs extra verification
  Enable SMS or access code authentication in the invite settings or require two-factor authentication for high-risk or regulated documents to increase signer assurance.

Practical best practices for signing PDFs

Follow these best practices when adding digital signatures in PDFs to ensure clarity, legal strength, and efficient processing across teams and systems.

Always require signer authentication methods

Enable at least one reliable authentication method such as email verification, SMS code, or knowledge-based authentication when sending legally significant documents to protect against unauthorized signing and disputes.

Use templates for repeat agreements

Create standardized templates with pre-placed fields to reduce errors, accelerate completion, and ensure consistent data capture for HR, sales, and compliance workflows.

Keep an audit trail for every transaction

Preserve the signNow Audit Trail with timestamps, IPs, and signer authentication details for each executed document to support legal admissibility and internal recordkeeping requirements.

Assign role-based access and field-level permissions so signers only see and edit fields relevant to them, reducing accidental changes and improving workflow security.
