Can I import a standard .pptx file into PREZ?

Yes. Drag and drop a .pptx file directly onto the PREZ interface. Slides, text and images are imported. Animations, transitions, charts, smart graphics and tables are not preserved — for full fidelity, export your slides as PDF or images and drop those.

Yes. PREZ is free in the browser. A subscription unlocks installable PWA mode and the rest of the Zigmoon Apps suite.

Does PREZ work offline?

Yes. PREZ is an offline-first PWA. All your decks and assets are stored in your browser via IndexedDB — no server, no account, no tracking.

Can I export to PDF or HTML?

Yes. PREZ exports to .prez (JSON), standalone HTML and printable PDF.
