Add a stamp to a PDF — approved, paid, received or your own seal
Offices still run on stamps: an invoice marked PAID, a drawing marked APPROVED, a letter stamped RECEIVED with the date it arrived, a contract draft labelled DRAFT, or a certificate carrying a company seal. The Add Stamp to PDF tool does the same job digitally, without printing and scanning the document.
Pick a ready-made stamp — drawn as crisp vector shapes and text, not a blurry picture — set its colour, frame, size, tilt and opacity, then tap the page where it belongs and drag it into place. You can also upload your own stamp or seal as a PNG or JPG, use several stamps on one document, and repeat any stamp on every page.
All of this happens in your browser: the PDF and your seal image are never uploaded.
How to stamp a PDF
- Drop your PDF onto the upload area or click to choose it. The first page appears on the right.
- Choose a ready-made stamp (APPROVED, PAID, RECEIVED, DRAFT, CONFIDENTIAL, COPY or your own text), or switch to “Image or seal” and choose a PNG or JPG.
- Adjust the ink colour, frame, date, size, rotation and opacity. Choose “All pages” if the stamp should repeat on every page.
- Tap the page where the stamp should go. Drag it to fine-tune the position; tap a stamp to select it and change its settings, or press × to remove it.
- Press “Stamp PDF” and download the stamped document.

Sharp at any zoom
Ready-made stamps are vector graphics and real text, so they print crisply and add only a few kilobytes.
Which stamp should you use?
| Stamp | Typical use | Usual colour |
|---|---|---|
| PAID + date | Invoices and bills once payment is made | Green or blue |
| RECEIVED + date | Incoming letters, applications and notices | Blue |
| APPROVED + date | Drawings, purchase orders, leave forms, proofs | Green |
| DRAFT | Versions still under review | Red |
| CONFIDENTIAL | Documents with restricted circulation | Red |
| COPY | Duplicates that must not be mistaken for the original | Blue or black |
Making a good seal image
- Photograph or scan your physical stamp on plain white paper in good light, then crop it tightly with Crop Image.
- A transparent background looks most natural. If your image has a white background, set the stamp opacity to around 85% and place it over empty space, or use a PNG editor to remove the white first.
- Use an image at least 600 pixels wide so the seal stays sharp when printed; the tool keeps up to 1,600 pixels.
- Round company seals usually look right at 15–25% of the page width, about 3–5 cm on A4.
Stamps, signatures and watermarks
A stamp marks the status of a document at one spot on the page. To sign a document by hand, use Sign PDF; to label every page with large, faint text across the middle, use Watermark PDF; for a line of text along the top or bottom of each page, use Add Header or Add Footer.
A stamp or seal image is a visual mark, not a cryptographic digital signature. It shows intent and status but does not prove who applied it or that the file has not changed since. Where a law or contract requires a certified digital signature, use the signing service it specifies.
Add Stamp to PDF FAQ
How do I add a stamp to a PDF?
Add your PDF, choose a stamp such as APPROVED or PAID (or upload a seal image), tap the page where it should go, drag it into place and press “Stamp PDF”. Then download the file.
Can I add a “Received” stamp with the date?
Yes. Choose RECEIVED — the date line is switched on automatically. Change the date with the date picker if the document arrived on another day.
How do I put my company seal on a PDF?
Switch to “Image or seal”, choose a PNG or JPG of your seal, then tap the page to place it. A PNG with a transparent background gives the most realistic result.
Can I stamp every page at once?
Yes. Select a stamp and choose “All pages”; it appears at the same position on every page.
Is a stamped PDF legally signed?
No. A stamp image shows status or approval but is not a digital signature. Use a certified digital signature where one is legally required.
Are my PDF and seal image uploaded?
No. Everything is processed in your browser, so both files stay on your device.
