The guide and instructions on this page are available while the tool loads.

PDF Watermark Tool adds visible text labels — Draft, Confidential, Internal, or custom branding — across every page with control over opacity, rotation, and placement.

Watermarks communicate status and ownership in review workflows but do not encrypt or prevent copying. Use PDF Protect when you need real access control.

Processing is local in the browser. Use light opacity on dense pages so underlying text stays readable.

Common problems this tool helps with

Situations where this workflow saves time.

Treating watermarks as security — they deter casual sharing but can be removed; use PDF Protect for real access control.

Opacity too high — text underneath becomes hard to read; start around 20–40% for draft marks.

Diagonal watermarks on dense pages — reduce font size or move to margins.

Client-facing drafts — pair a DRAFT watermark with a filename that includes the date and version.

Frequently asked questions

Does a watermark stop someone from copying the PDF?

No. Watermarks are visible labels, not encryption. They discourage misuse but do not prevent editing or removal by someone with PDF software.

Is my PDF uploaded?

No. Watermarking runs locally in your browser.

Can I watermark only some pages?

This tool applies the text across the document. Split or extract pages first if only a section needs a label.

What opacity works for draft copies?

Light gray text at low opacity keeps the page readable while still showing the draft status.
