What does Add Watermark PDF do?
Add Watermark PDF is a free online tool that can overlay watermark text on every page of a PDF. The PDF result from Add Watermark PDF is a separate copy to inspect before you use it elsewhere. One possible use is draft reports visibly marked before review.
A PDF watermark puts the text you choose across each page at a slant. A draft label can help readers tell a working copy from the final file.
The starting text is CONFIDENTIAL, which you can change to fit your own need. The server makes a text image and places it over the images of your pages.
A tall page and a wide page may show that mark in different places. Small type or pale charts can be hard to read under the added text.
Use a short label and check the pages before you share the marked copy. A short draft label is easier to read than a long warning.
Pale charts can be hard to see beneath a diagonal mark. Check a chart page at normal reading size.
Readers can still copy or photograph a marked page. Use file access controls if the material needs restricted access.
