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.

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.
What PDF Verified is, and what it is not
Electronic signature law is settled in broad terms and specific in the details. The ESIGN Act, UETA, eIDAS and their equivalents recognise electronic signatures across more than 190 countries, and what decides a particular case is intent to sign plus evidence connecting the signature to the signer, which is what the audit certificate records. Certain document types carry their own formalities wherever you are: deeds, wills, some property instruments, and anything requiring a witness or a notary. Sign only what you are authorised to sign, since applying another person signature without their authority is forgery whatever tool is used.
PDF Verified is a tool for preparing, signing, stamping and checking documents. It is not a law firm, a compliance service or a forensic examiner, and nothing here is legal, financial or compliance advice. Requirements differ by country, by document type and by the party asking, so check what applies to your document before you rely on it, and take advice where the document matters. You are responsible for the documents you create, sign and send, and for having the authority to do so: signing or stamping in somebody else name, or as an organisation you do not represent, is forgery whatever tool is used. To the extent the law allows, we accept no liability for how a document made with this tool is used or relied on. The full position is in our terms of service.
