Watermark PDF
A light diagonal text across every page.
Stamp every page with a light diagonal text — “DRAFT”, “CONFIDENTIAL”, a company name — to mark a document’s status before sharing it.
The watermark is drawn in your browser, under your eyes, and the original file on disk stays untouched.
How it works
Drop a PDF into the box above.
Type the watermark text.
Click “Watermark” and download the stamped file.
Why this tool
Readable but unobtrusive
Large, light-gray, diagonal — visible at a glance without making the page unreadable.
Every page, consistent angle
The same stamp lands identically on all pages, portrait or landscape.
Local stamping
Sensitive drafts are watermarked on your device, not on a server.
Frequently asked questions
Can the watermark be removed later?
It becomes part of the page content, like printed ink. There is no one-click removal — which is exactly what a watermark is for.
Can I use my own wording?
Yes — any text you type becomes the stamp: language, names and numbers included.
Will it cover important content?
The stamp is drawn semi-transparent under a diagonal angle, so text underneath remains readable.
Is my document uploaded?
No, watermarking runs entirely in the browser.
