Watermark PDF
Stamp a document as “Confidential”, “Draft”, or your own text. The watermark is placed diagonally on every page — locally, with no upload.

Tune the strength so the mark does not obscure the content.
In your browser
The document is never uploaded — the watermark is applied locally.
Frequently asked questions
Does it support Cyrillic?
Yes. Latin text uses a built-in standard font; for Cyrillic, a Unicode font (PT Sans) is embedded automatically so the watermark renders correctly.
Is my file uploaded?
No. The watermark is added entirely in your browser — nothing is sent anywhere.
Is it applied to every page?
Yes. The text is placed diagonally across the centre of every page in the document.
Can I remove the watermark later?
The mark is baked into the new file. Keep the original if you may need an unmarked version.
