How to Add an Electronic Signature to a PDF
PDF Porter adds a visible electronic signature mark to a PDF. It is not a certificate-backed digital signature and does not independently verify identity, approval time or whether the document changed later. Check what the receiving organisation accepts before relying on it.
Confirm the document and signing requirement
Read the complete document, verify names and dates, and confirm that a visible electronic signature is acceptable. Some legal, regulated, government or financial processes require a particular signing platform, witness or digital certificate.
- Sign only documents you understand and intend to approve
- Do not use another person’s signature without authority
- Ask the recipient about formal signature requirements
Place the signature carefully
Create or select your signature, place it inside the intended signature area and keep it clear of dates, names and contractual text. Check the correct page before downloading.
Review and retain evidence
Open the signed PDF and confirm the signature is visible at normal zoom. Keep the final agreed document and any separate confirmation or audit evidence required for the transaction. This guide is practical information, not legal advice.
Final checklist
- Visible e-signature is accepted for this purpose
- Correct document and page were used
- Signature does not cover other text
- Final signed copy was retained
