What is Certified True Copy?

A copy of a document stamped and signed to certify it is a faithful, unaltered reproduction of the original.

A certified true copy is a duplicate of an original document, an ID, a certificate, a contract, that an authorised person stamps and signs to attest it faithfully matches the original. Banks, embassies, courts, and registries routinely require certified copies. PDF Verified lets an authorised user apply a "Certified True Copy" stamp with a date and serial, seal the file with a SHA-256 hash, and expose a public verification link so the certifying act is itself auditable.

Drop your document here and sign it now. PDF, Word and Excel all work: a .docx or .xlsx is laid out in your browser exactly as it was written, so there is nothing to convert first. Add a signature, a date, a company stamp or a watermark, then download it sealed. Free to start, no account, and the file is never uploaded to open it.

Who can certify a copy

Typically a notary, lawyer, commissioner for oaths, or an authorised officer of the issuing organisation. The certifier applies a stamp and signature attesting the copy is true. Digitally, the certifier's identity, the timestamp, and a tamper-evident hash are captured automatically.

Tamper-evidence

Because PDF Verified hashes the sealed copy with SHA-256 and publishes the hash on a verification page, anyone can confirm the certified copy has not been altered since it was certified, something a paper certified copy cannot offer.

What PDF Verified is, and what it is not

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.
