Why Mark Your Export Documents

Watermarks and stamps protect sensitive commercial documents — price lists, bank guarantees, invoices and contracts — from being misused when shared with buyers, freight forwarders or consultants. A diagonal CONFIDENTIAL watermark or a colored CERTIFIED COPY stamp makes unauthorized reproduction obvious and discourages it.

All marking is applied locally with pdf-lib, so your documents never leave your device. Combine with the PDF Tools page for a complete, private document workflow.

Frequently Asked Questions

Can the watermark be removed by the recipient?
A rendered text watermark is part of the page content and cannot be removed without re-processing the file. It deters casual misuse and clearly identifies the document owner.
Does this tool add its own watermark?
No. The tool is completely free with no added branding or watermark on the output.
Is a CERTIFIED COPY stamp legally meaningful?
A stamp alone is decorative. True certification requires the signature and seal of a notary or authorized officer. Use the stamp for internal marking and obtain proper attestation where required.
What watermarks can I add?
Text watermarks with opacity and rotation, CONFIDENTIAL-style stamps and page numbers — all applied in your browser with pdf-lib.
Are my PDFs uploaded?
No. Watermarking runs entirely in your browser — your documents never leave your device.
Is the PDF Watermark & Stamp free to use?
Yes. The PDF Watermark & Stamp is 100% free for personal and commercial use — no registration, login or payment required.
