About Electronic Signatures
This tool places a visual signature image — a rendering of your handwritten signature — onto your PDF. This is sometimes called an e-signature or electronic signature image. The result looks exactly like a wet ink signature on the page.
For most internal documents, agreements between trusted parties, and simple acknowledgments, a visual signature image is entirely sufficient. Many businesses and organizations accept visually signed PDFs without requiring a cryptographic certificate.
For legally enforceable contracts in regulated contexts (finance, healthcare, real estate, government filings), you may need a certified e-signature platform that creates a tamper-evident digital signature with an audit trail — such as DocuSign or Adobe Sign. Check the requirements in your specific jurisdiction and context.
