FAQ
Is my PDF uploaded to a server?
No. Watermarking runs entirely in your browser. Files never leave your device.
What placement styles are available?
Three styles: diagonal (text rotated 45° across the page center), tiled (repeated grid across the full page), and centered (horizontal text in the center of the page).
Can I watermark only specific pages?
Yes. Leave the page range blank to watermark all pages, or enter a spec like 1, 3-5 to target only those pages.
