Design tips that make a Rectangle stamp look official
- Export as a transparent PNG. A stamp with a white box behind it looks pasted-on the moment it touches letterhead; a transparent one sits cleanly over text and lines.
- Keep ring text short. On round seals, the company or authority name curves around the edge, 40–60 characters reads best. Put registration or licence numbers on the bottom arc.
- Use a light aging texture. A slight fade reads like a genuine inked impression instead of a sticker. The stamp maker has a texture slider for exactly this.
- Classic ink colors read as official. Deep blue and red are the conventions for Rectangle stamps; keep logos monochrome inside the seal.
Make it verifiable, the upgrade rubber can't match
The weakness of every physical Rectangle stamp is that one photographed impression can be copy-pasted onto anything. PDF Verified fixes this with serialization: each application can carry a unique serial number and a QR code that resolves to a public verification page showing who issued the stamp and which document it belongs to. A pasted image fails that scan instantly, which flips the forgery economics of the Rectangle stamp completely.
Is a digital Rectangle stamp legally valid?
In most jurisdictions the signature makes the document binding and the stamp is supporting evidence of authority, and electronic seals are recognised wherever commercial practice expects them (Kenya's KICA, the UAE's Electronic Transactions Law, eIDAS in the EU). A serialized digital Rectangle stamp actually carries more evidential weight than ink, because it comes with a tamper-evident record of when and where it was applied.

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.
