Frequently Asked Questions
What is the "Tiled" position?
Tiled mode repeats the watermark in a grid pattern across the entire page. This is commonly used for "CONFIDENTIAL" or "DRAFT" stamps on business documents.
Does watermarking affect PDF text?
The watermark is rendered as an overlay on each page. For PDFs, each page is re-rendered with the watermark embedded, so the watermark cannot be removed by the recipient.
Are my files uploaded anywhere?
No. All watermarking happens directly in your browser. Your files never leave your device.

Working with PDFs regularly?
This tool handles the occasional job in your browser. For editing text inside a PDF, converting to Word, redacting or signing, you need a desktop editor — Kofax Power PDF is a one-off licence rather than a subscription.
