Frequently Asked Questions

Can I control the watermark's transparency?

Yes, use the Opacity field — lower values (e.g. 0.15) create a subtle watermark, higher values make it bold and visible.

Can I add a watermark to only some pages?

Currently the watermark applies to every page in the document to keep the tool fast and simple.
