Questions
Can the watermark be removed?
The watermark is added to the page content, so it stays when the PDF is opened, printed or shared. Like any PDF watermark, it's a visible marker, not copy protection.
Which characters can I use?
Latin letters, numbers and common symbols for now. Support for other alphabets is coming.
Can I add an image or logo as a watermark?
Not yet. Text watermarks only for now.
