Stamp text across your pages — DRAFT, CONFIDENTIAL, a company name — with control over colour, size, rotation and opacity. Apply it to every page or only the ones you select.
The watermark is drawn into the page content, so it travels with the file and appears when it is printed or opened anywhere. It is a deterrent and a label, not a security control: anyone determined can still remove it.
Because the stamping happens on your device, a confidential document does not have to be uploaded to a stranger’s server just to be marked confidential.

Where it runs
In your browser; nothing uploaded
Not for: Security — a watermark deters casual reuse, it does not lock or encrypt the document.
Frequently asked questions
Are my files uploaded to a server?
No. This conversion runs entirely inside your browser using your own device’s processing power. The file never leaves your computer or phone, which is why it also works when your connection drops.
Can I watermark in Arabic?
Not yet. The built-in PDF fonts cover Latin characters only, so Arabic is refused with a clear message rather than producing broken glyphs. Latin text works fully.
Can the watermark be removed?
It is part of the page content, so it survives normal viewing, printing and copying — but treat it as a label rather than protection.
