2.Type the text and choose size, angle and opacity.
3.Download the PDF.

Tips for Linux

• No install or package needed.
• Works the same on any distribution.

What happens to the rest of the page

• The watermark is added as a layer; the original page content is not rewritten.
• Works on every page at once.
