Examples
QA before client send
Spot 3 hidden slides that shouldn't ship and 4 slides without speaker notes that need them.
Time estimation
At ~2 min/slide, a 42-slide deck = ~85 min — handy for fitting a webinar into a 90-minute slot.
Media audit
Confirm a deck contains the 6 expected embedded videos before the offsite venue (no Wi-Fi available).
Common use cases
- QA-ing decks before delivery (hidden slides, missing notes)
- Estimating presentation duration
- Auditing media assets in a deck
- Bulk-checking slide counts across a folder of decks
- Verifying compliance with "max N slides" submission rules
Troubleshooting
- Slide count differs from PowerPoint
- PowerPoint counts hidden slides in the total; the counter reports visible/hidden separately. Add the two to match.
- Speaker-note count seems low
- Empty notes (with the placeholder text only) aren't counted as real notes. The counter looks at note length > 0 characters.
- Image count includes background art
- Slide-master backgrounds count as images. Toggle "exclude master images" to count only content images.
