How to make a company stamp online
- Pick a template or shape. Start from a classic round company stamp, a double ring, a round stamp with a date band, an oval, an address block or a “PAID” stamp.
- Type your wording. The company name runs around the top of the ring and your location or slogan around the bottom. Up to three centre lines hold a registration number, address or phone number.
- Add a date and logo if you need them. The date sits in its own colour like a dater stamp. A logo can be re-inked in the stamp colour so it looks pressed rather than pasted.
- Choose the ink and texture. Blue, violet, red, black, green or your own colour, with a clean, light or worn ink finish.
- Set the real size and download. Sizes are in millimetres, so a 40 mm stamp prints at 40 mm. Download a transparent PNG, or go to Stamp a PDF.
How to stamp a PDF without printing it
Open the Stamp a PDF tab and drop in your document. Click Add stamp and drag it into place — use the corner handle to resize and the round knob to rotate it slightly, the way a hand-pressed stamp usually sits. You can put the stamp on every page at once, add a signature image (its white background is removed for you), then download the stamped PDF. The ink is blended into the page, so text underneath still shows through as it would on paper.
Which stamp shape should a business use?
| Shape | Typical use | Common size |
|---|---|---|
| Round (single or double ring) | Company or organisation stamp on letters, delivery notes, receipts, contracts | 38–45 mm |
| Round with date band | Received / approved stamps where the date matters — stores, accounts, front desks | 40–45 mm |
| Oval | Schools, churches, NGOs and associations that want a softer look | 45 × 30 mm |
| Rectangle / address block | Name, address, phone and tax number on invoices and envelopes | 55 × 25 mm |
| Word stamps (PAID, RECEIVED) | Marking invoices and documents as processed | 40 × 15 mm |
What to put on a company stamp
Requirements differ from country to country, but most businesses include the registered company nameexactly as on the certificate of incorporation or business name registration, a location(city or region), and contact details such as an address or phone number. Some add acompany registration or tax number on rectangular stamps used for invoicing. Keep the wording short — long text on a 40 mm ring becomes hard to read when it is pressed or printed small.
Digital stamp vs electronic signature
A stamp shows that a document came from or was approved by a company; a signature shows that a particular person approved it. Most organisations expect both together — a stamp next to an authorised signatory’s signature. If you need a signature with a verifiable audit trail (who signed, when, from where), use a proper e-signature service alongside the stamp.
