PowerPoint Slide Numbers

PowerPoint's own slide-number setting depends on the master and the layout placeholders, which is why it so often shows on some slides and not others. This writes the number onto each slide directly.

Numbers are written as 3 / 12 so the audience always knows how much is left. Combine it with a draft or confidential watermark if you need both.

PowerPoint Watermark & Slide Numbers

Stamp a draft or confidential watermark on every slide, add slide numbers, or both — without touching the master.

Frequently asked questions

Will the numbers update if I add slides later?
The numbers are written into the file as text, so if you add or reorder slides afterwards, run the tool again to renumber them.
Does it work with decks that already have page numbers?
Yes, but you will see two sets. Delete the existing ones first, or leave the tool's numbering off and keep the deck's own.
