How to stamp a PDF
You can stamp a PDF entirely online, no rubber stamp, ink pad, printer or scanner. Design a stamp (a round company seal, an APPROVED / PAID / RECEIVED text stamp, or a dated stamp) or upload a transparent PNG of an existing one, place it on the page, and download the stamped PDF. Designing is free; downloading a stamp is $1.50 pay-as-you-go or free on a paid plan. Turn on serialization and each stamp carries a unique number and a public QR verification link, so a copied image can never pass as genuine.

Frequently asked questions
How do I stamp a PDF for free?
Design your stamp free in the PDF Verified stamp maker and place it on your PDF. Downloading a finished stamp is $1.50 pay-as-you-go, or free and unlimited on a paid plan.
How do I add a date stamp to a PDF?
Add a {{DATE}} line to your stamp and it fills in automatically when applied, so every impression carries the correct date. You can format the date and combine it with a serial number.
Can I upload my own stamp image?
Yes. Save your existing stamp as a transparent PNG and upload it, then position it on the PDF. For a verifiable version, rebuild it in the maker so it can carry a serial and QR verification.
How do I put an APPROVED or PAID stamp on a PDF?
Pick the APPROVED or PAID preset in the stamp maker (or type your own text), place it on the PDF, and download. Enable serialization so each approval is uniquely verifiable.
Can I add a stamp to a PDF?
Yes. Upload the PDF to PDF Verified, place a stamp (a company seal, an APPROVED/PAID/RECEIVED text stamp, a date stamp, or your uploaded stamp image) anywhere on any page, and download the stamped file, no printing.
Why should you use a stamp on a PDF online?
An online stamp is faster and cheaper than a physical rubber stamp, needs no ink or scanner, and, unlike a pasted image, a PDF Verified stamp can carry a serial number and QR verification so recipients can confirm it is genuine, not copied.
How do I create custom digital stamps?
Open the stamp maker, pick a shape, and type your own text, dates and serial fields; add a logo or draw a signature inside the stamp. Save it to reuse, and apply it to any PDF. It’s a free custom PDF stamp generator.
What is a digital PDF stamp?
A digital PDF stamp is a stamp or seal applied to a PDF electronically instead of with a physical rubber stamp, for example an APPROVED mark, a company seal, or a dated stamp. In PDF Verified it can also carry a serial number and QR verification, which a pasted image cannot.
Can I stamp all pages of a PDF?
Yes. Place your stamp and apply it across every page of the document, so multi-page contracts and reports carry the same seal or approval mark on each page before you download.
Will the stamp have a white box behind it?
No. Stamps export as transparent PNGs cropped tight to the ink, so they sit cleanly over letterhead, colour and signatures.
How do recipients confirm the stamp is real?
With serialization on, every stamp resolves to a public verification page showing its name, serial, the document it belongs to, and whether it has been revoked, so a pasted copy fails the scan.
What PDF Verified is, and what it is not
A stamp identifies who issued a document. It is evidence rather than a formality that makes a document binding on its own, and it should only ever be made and applied for a business or an office you are authorised to act for: a mark that imitates another organisation in order to pass a document off as theirs is forgery in most places. Where a registry, a bank or a counterparty requires a particular form of seal, that requirement comes from them.
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.
