About Watermark PowerPoint

Add a watermark to PowerPoint decks you send out for review, share with a partner under NDA or post online as a sample. Type the text, choose Diagonal or Horizontal and set the color, opacity and size, and every slide gets the same semi-transparent label across its middle. If the deck is too heavy to share or upload, Compress PowerPoint shrinks the photos in it.

The watermark is a regular text box named Watermark, placed on top of each slide so pictures and full-slide backgrounds can't hide it. That also means it can be selected: in PowerPoint's Selection Pane you can nudge it on a slide where it covers something important, or delete it. For a copy that nobody can edit, convert the watermarked deck to PDF.

Why use Cubfile for this

  • Every slide, one pass

    The same label is added to all slides, whatever layout they use.

  • Always visible

    It sits above pictures and backgrounds, so it can't disappear behind a full-slide photo.

  • Easy to adjust

    Named Watermark in the Selection Pane, it can be moved or resized on any slide.

  • Tilted or level

    Diagonal sets it at an angle across the slide, and Horizontal keeps it straight.

FAQ

Watermark PowerPoint: questions and answers

Can I add a watermark to PowerPoint slides in my brand color?
Yes. Pick any color and set the opacity from faint to solid. Light gray at low opacity is easiest to read through, while a brand color at 40% gives a stronger mark.
Will the watermark cover my content?
It's semi-transparent and centered, so text underneath stays readable. If it sits on top of a key chart, select it in PowerPoint's Selection Pane and move it on that slide. Paging through the result in Office Viewer is a quick way to spot those slides.
Can the watermark be removed?
Yes, by anyone who edits the file in PowerPoint. When the mark must stay, send a PDF of the watermarked deck instead.
Is Watermark PowerPoint free to use?
Yes. Visitors get 2 tasks and free accounts 2 a day, with decks up to 50 MB. VIP removes the daily limit and accepts files up to 1 GB.
What happens to my presentation?
It's processed in an isolated process after an encrypted upload and deleted automatically one hour later, together with the watermarked copy. Nobody looks at your slides.
