Stamp DRAFT, CONFIDENTIAL or your own text across pages. This works on the PDF Microsoft PowerPoint exported, so you do not need the original file.

- 2.Type the text and choose size, angle and opacity.
- 3.Download the PDF.
How Microsoft PowerPoint writes PDFs
- • Each slide becomes one page.
- • Text boxes are placed independently.
- • Theme fonts are embedded as subsets.
What that means when you add a watermark
- • Each text box on a slide is edited on its own and keeps its alignment. Charts keep their shapes; only their text labels change.
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.
Questions people ask
+Can I remove a watermark later?
Keep the original file. Watermarks are added to the copy you download.
+Is it better to edit in Microsoft PowerPoint?
If you have the original Microsoft PowerPoint file and a lot to change, yes. For quick changes to the PDF itself, editing the PDF is faster and keeps it exactly as sent.
