Frequently asked questions
Which characters can a watermark have?
Latin and Cyrillic letters are supported, on several lines if you like. Emoji and CJK characters aren't supported in a watermark yet - you'll get a message about it rather than a broken file.
Can the watermark be removed from the PDF later?
The watermark is added as separate text over the pages, so it can be deleted in a PDF editor. It's a notice for the reader, not copy protection.
Will the document turn into an image?
No. The pages stay as they were: the document text can be selected and searched, and links work. The watermark text also gets into search and copying.
How do I cover the whole page with the watermark?
Choose "Diagonal grid" - the text repeats across the whole page. An opacity of 20–30% keeps the document readable.
