Frequently Asked Questions

Can I add a semi-transparent watermark so the text beneath is still readable?

Yes — you can adjust the watermark opacity from 10% to 100%, allowing you to create subtle watermarks that brand the document without obscuring the underlying content.

Can I use an image as a watermark instead of text?

Yes — upload a PNG or SVG logo or stamp image to use as an image watermark instead of, or in addition to, a text watermark.

Will the watermark be applied to every page?

By default the watermark is applied to all pages. You can also choose to watermark only specific pages or page ranges if needed.
