Frequently Asked Questions
Can I use an image as a watermark?
Currently only text watermarks are supported. You can customize the text content, font size, color, and opacity.
Where does the watermark appear on the page?
The watermark is placed diagonally across the center of each page, similar to standard document watermarking. You can control opacity to make it subtle or prominent.
Can I watermark only specific pages?
The watermark is applied to all pages in the document. For selective watermarking, split the PDF first, watermark the relevant pages, and merge them back.
Can someone remove my watermark?
Text watermarks are embedded into the page content. While technically possible to remove with PDF editing tools, it requires effort and intent.
