Company seal vs stamp on a PDF — what’s the difference?
A company seal is usually a round or oval mark with the legal company name (and sometimes registration details). A stamp is a broader term for any inked mark — approved, paid, received, or a custom seal. On PDFs, both are placed the same way: as a graphic overlay you position and export.

In many markets (including Nigerian business and admin workflows), the company seal is the circular or oval device used on letters, certificates, and filings. It typically shows the registered company name around the rim and a short centre line or logo.
Sealify’s circle and oval styles are built for this look — company name, optional subtext, colour, and logo.
Document stamp
“Stamp” also covers status marks (PAID, COPY, CONFIDENTIAL) and rectangular or corner seals. If your office still keeps a physical rubber stamp for approvals, a digital stamp on the PDF is the same idea without print–scan.
Which should you use?
Use a round/oval company seal when the document should look officially issued by the company. Use a simpler stamp when you only need a quick status or departmental mark. Sealify supports both shapes so one tool covers the common cases.
Not a substitute for legal formalities
Placing a seal on a PDF does not by itself create a notarisation, CAC filing, or court-ready certification. Follow your counsel or regulator when a wet-ink seal or certified copy is required.
