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.
