Frequently asked questions

Can I watermark only some pages?
Yes. Choose all pages, first, last, or a custom range such as 1-3,5.
Do you upload my files?
No. The PDF and watermark image are processed locally in your browser.
Will text stay selectable?
Yes. Watermarks are drawn on top of existing pages without rasterizing the whole document.
