How to add a watermark
Upload a PDF, type your watermark text, then adjust size, opacity, angle and colour. The watermark is placed in the centre of every page.
Character support
The watermark uses a standard PDF font, so it supports basic Latin letters, numbers and common punctuation.
Frequently asked questions
Is my file uploaded anywhere?
No. Everything happens inside your browser on your own device, so your files never leave your computer and there is no file-size limit imposed by a server. Very large files are limited only by your device's memory.
Can the watermark be removed?
It's drawn into the page content, so it can be edited out by someone with PDF-editing tools. It deters casual reuse but isn't secure protection.
