Why This Takes Longer Than It Should
"Come into the office just to stamp this" — and the print-stamp-scan round trip — survive even for documents that were born digital. The usual workaround makes things worse: free online seal generators that take your surname as input and hand back a stamp image, quietly logging both your name and the fact that you needed a seal for something.
What's Actually At Risk Here
- ✓A seal impression is your name. Generating it in the browser means neither the name nor the fact that you needed a seal is recorded anywhere.
- ✓The generated seal goes straight into PDF Markup via the clipboard, so no stray image file is left sitting on your desktop.
- ✓The stamped PDF is finished in the browser too — contracts and applications never pass through an external service.

Where People Get Tripped Up
These catch people out even when the steps are followed correctly. Skimming them first saves a redo.
- This covers informal seals only. Registered corporate and bank seals require the physical registered stamp and cannot be replaced by an image.
- Whether a digital seal is accepted is up to the recipient's policy — check first, especially with government offices and banks.
- Pasting a seal with an opaque background will cover the text beneath it. Keep the background transparent and nudge the position.
Frequently Asked Questions
- Is this digital stamp legally valid?
- This tool pastes a seal image onto a PDF and is not a certified electronic signature under e-signature law. It is intended for internal documents, confirmations, and personal use where a formal electronic signature is not required.
- Can I create stamps other than personal seals?
- Yes. You can create round stamps, square stamps, date stamps, company seals, and more. Font, size, and color are all customizable.
- Can I stamp scanned documents (image-based PDFs)?
- Yes. PDF Markup works with both text-based and scanned/image-based PDFs.
