Common use cases

  • Drafts: mark in-progress documents as "DRAFT" before final approval.

  • Branding: add a company name across internal documents.

Frequently Asked Questions

Does this upload my PDF anywhere?
No. The watermark is applied entirely in your browser — your file is never uploaded.
Can I control how visible the watermark is?
Yes — use the opacity slider to make it subtle (light, background-style) or bold (highly visible).
Is the watermark applied to every page?
Yes, the same watermark text is stamped diagonally across every page of the document.
Can I remove a watermark added with this tool later?
Not with this tool — once saved, the watermark becomes part of the page content. Keep your original, un-watermarked file if you might need it later.
