How to use it
- Choose the PDF.
- Type the watermark and set how visible it should be.
- Download the marked PDF.
A watermark tells the next reader that a file is a draft, a sample, or meant for one person. SKY13.app draws the words across the middle of each page at an angle and at the opacity you pick.
The mark sits on top of the page. It does not lock the file. Someone can still copy pages. Use it as a visible label, not as a security control. Keep the text short so it stays readable.
Questions
Can I watermark one page only?
This tool marks every page. Add a note to a single page with Edit PDF instead.
Will the watermark hide the text underneath?
At a low opacity it stays faint. Raise the slider if you want it stronger, and check a page before you send the file.
