Frequently asked questions
Can I use an image or logo?
Not currently. The tool applies a text watermark across each page.
Can I watermark only some pages?
The watermark is applied to every page. Split the file first if you need it on a subset.
Can the watermark be removed later?
It is drawn into the page content, so it is not a layer readers can simply toggle off.
Will it hide my text?
Lower the opacity so the mark sits behind readable content.
