- 2.Type the text and choose size, angle and opacity.
- 3.Download the PDF.
Tips for iPhone
- • Turn the phone sideways for a wider page.
- • Tap text to edit; the keyboard stays below the text box.
- • Export saves to Files, where you can share it.
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.
