What this tool is (and isn't)
This tool places a visual signature image on a PDF. It is not a cryptographic e-signature: no public-key cryptography, no timestamping, no certificate chain, and no validator signal in Adobe Reader. That means the result has the same legal weight as a photo of a handwritten signature pasted into a document — useful for informal agreements, internal approvals, and situations where visual presence is enough, but not appropriate for legally-binding contracts. For legally-binding e-signatures, use a dedicated service like DocuSign, Adobe Sign, or HelloSign, which add an auditable cryptographic trail. Use this tool when you want a quick visual signature without paying for a subscription and without uploading sensitive files to a third-party server.
For document workflows that pair well with a visual signature, combine this tool with other LlamaPDF utilities. Add text, dates, or annotations to fill in form fields before signing, flatten the signed PDF so the signature becomes a permanent part of the page and can't be moved, or add a password before sharing. The tool works on any device — desktop, tablet, or phone — with no account, no installation, and no page limits.
