FAQ
Is this tool free?
Yes — no sign-up, no installation, completely free to use right away.
What is this tool?
This tool stamps a text watermark across every page of a PDF. Type a word like “Confidential” or “Draft” and it's added diagonally over each page before you download. It's a simple way to mark ownership or status on documents you share. The file is processed entirely in your browser and never uploaded.
Are my uploaded files sent to a server?
No. Everything runs only on your own computer, inside your browser, and your files are never sent to a server or anywhere else. So you can use it with complete peace of mind, without worrying about your file contents leaking.
Is the original PDF uploaded?
No - the watermark is applied in your browser; your file never leaves your device.
