Frequently Asked Questions (FAQ)
What is Mosaic Mode?
Mosaic Mode (or Tiling) repeats your watermark text or logo diagonally across the entire page. This offers maximum protection against unauthorized copying.
Can I watermark specific pages only?
Yes. You can choose to apply the watermark to 'All Pages' or specify a range (e.g., '1' for just the cover page) using the dropdown menu.
Can I use different fonts?
Yes. We support standard professional fonts including Helvetica, Times Roman, and Courier so you can match the document's tone.
Is it secure?
Absolutely. We use client-side processing. Your PDF and your watermark image are processed entirely within your browser and never uploaded to our servers.
Is it free?
Yes, 100% free with no limits on the number of documents you can protect.
