How it works
A watermark is text stamped across a page, commonly used to mark a document as a draft, confidential, or to indicate ownership before sharing a file publicly. This tool stamps your chosen text diagonally across every page at a semi-transparent opacity, so it's visible without obscuring the original content underneath.
How to use it
- Choose your PDF — Works on any document.
- Type your watermark text — For example "DRAFT" or "CONFIDENTIAL".
- Download your watermarked file — Applied to every page automatically.
Common questions
Will the watermark show up when the PDF is printed?
Yes — the watermark becomes part of the page content, so it appears both on screen and when printed.
Can I use a logo image instead of text?
Not currently — this tool stamps text only.
Can I remove a watermark after adding it?
Not with this tool — once applied, it's part of the saved file. Keep a copy of your original in case you need an unwatermarked version later.
Is my file uploaded anywhere?
No. This tool processes your file directly in your browser. It is never sent to a server, stored, or seen by anyone.
Is there a file size or daily limit?
No daily limit. Very large files (roughly 100MB+) may be slow since everything runs on your own device's memory rather than a server.
Do I need to create an account?
No. Every tool on this site is free and requires no sign-up.
