When you would use this
This replaces the print-sign-scan loop that most paperwork still assumes: rental agreements, permission slips, invoices, delivery notes, NDAs. It is worth knowing that this produces a visible signature, which is what the overwhelming majority of documents actually ask for, rather than a cryptographic digital signature backed by a certificate.
Questions about Sign PDF
- Are my files uploaded to a server?
- No. Every tool on this site runs inside your browser. Your file is read from your disk into your own browser's memory, processed there, and written back out. You can confirm this yourself: open your browser's developer tools, switch to the Network tab, and run the tool — you will not see your document being sent anywhere. It also means the tools keep working if you go offline after the page has loaded.
- Is this a legally binding signature?
- In many places an image of your signature on a document is accepted the same way a scanned signature is, but this is not legal advice and the rules differ by country and by document type. If you need a certificate-backed digital signature with an audit trail, that requires a service that issues certificates, which this is not.
- Can I ask someone else to sign?
- No. Requesting a signature from another person means sending them the document, which means a server holding it. That is the one thing this site does not do, so signature requests are outside what it can offer.
- Will my signature be stored anywhere?
- No. It exists in the page's memory while you work and is gone when you close the tab. Nothing is uploaded and nothing is saved between visits.
