Question 1

Does this online tool upload my PDF and seal?

Accepted Answer

No. PDF parsing, seal compositing, perforation-seal slicing and export all happen locally in your browser — files are never uploaded to any server. Private and secure.

Question 2

How is the perforation seal split automatically?

Accepted Answer

When the perforation seal is on, the tool divides the seal image vertically into the same number of slices as the PDF's page count and fits each slice to the right seam of its page. Line all pages up in order and the seal is fully restored.

Question 3

Can I stamp each page of a multi-page PDF separately?

Accepted Answer

Yes. Switch pages and stamp anywhere on each one — what you see is what you get. On export, the stamps from every page are written into the PDF.

Question 4

What's the difference between watermarked and watermark-free export?

Accepted Answer

Watermarked export is free and overlays a light site watermark on each page. Upgrade to Pro to export a watermark-free stamped PDF, suitable for formal layout and delivery.

Question 5

Does this stamp have legal effect?

Accepted Answer

This tool is mainly for document layout, proof previews and personal-use stamping effects. For legally effective electronic seals, please use a compliant electronic-signature and digital-certificate service.
