Frequently Asked Questions

.pptx and .ppt files are supported.
Will slide animations appear?
No — PDFs are static. Animations and transitions are not captured; each slide becomes a page.
Is there a slide limit?
No server limit. Large decks may take a moment to process depending on your device.
Are my slides private?
Yes. Processing is entirely local — nothing is uploaded.
