About this tool
A watermark makes the status or ownership of a document obvious at a glance — think DRAFT on a work-in-progress report, CONFIDENTIAL on internal files, or your brand name on documents you share publicly. This tool stamps the text onto every page locally on your device, so sensitive documents stay private while you mark them as such.
Frequently asked questions
Can the watermark be removed later?
The watermark becomes part of the page content, so casual readers can't remove it. Like any visible watermark, however, it is not a security feature — determined users with editing tools may be able to strip it.
Does the watermark cover my text?
The watermark is drawn semi-transparently, so the underlying content stays readable. Use the "Light" opacity for text-heavy documents.
Is my PDF uploaded anywhere?
No. Watermarking happens entirely in your browser — the file never leaves your device.
