How to add a signature line to a PDF
There are two things people mean by “add a signature line to a PDF”: drawing a blank line to sign later, or placing a real signature field so someone can actually sign the document. PDF Verified does the second, and better, one. You drop a labelled signature block exactly where it belongs, assign it to a signer, and send the PDF for signature; the signer types or draws their signature into that field and the finished PDF comes back with a tamper-evident seal and audit trail. Setting up the fields is free.
How to add a signature line to a PDF — step by step
- Upload the PDF — Open PDF Verified and upload the document that needs signing, a contract, form, agreement or letter.
- Drag a signature field onto the page — Drag a Signature field to where the signature line should be, then add Date, Initials or Name fields alongside it if you need them. Assign each field to the person who should fill it.
- Send for signature (or sign it yourself) — Send the PDF to your signer, or sign it yourself. The finished document comes back with a tamper-evident SHA-256 seal, an audit certificate, and an optional public QR verification link.
What you get
- Place real signature, date, initials and name fields, not just a blank line.
- Assign each field to a specific signer so everyone knows where to sign.
- Legally binding under ESIGN, eIDAS and UETA.
- Tamper-evident seal and audit certificate on the completed PDF.
- Optional public QR verification so the signature can be checked later.
Frequently asked questions
How do I add a signature line to a PDF so someone can sign it?
Upload the PDF to PDF Verified, drag a Signature field to where the line should be, assign it to your signer, and send it. They sign into that field and you get the completed, sealed PDF back, more useful than a blank drawn line.
Can I just draw a blank signature line?
You can add a line or “Sign here” label as text, but a real signature field is better: it captures an actual signature, records who signed and when, and seals the file so it can’t be altered afterwards.
Can I add several signature lines for different people?
Yes. Add a signature field for each signer and assign each one to the right person; each signer only fills their own fields.
Is a signature collected this way legally binding?
Yes. Signatures collected through PDF Verified are legally binding under ESIGN, eIDAS and UETA, and come with an audit certificate as evidence.
