About PPTX
A PPTX is a ZIP of XML files: each slide, its layout and master, the theme's colors and fonts, the pictures, charts and media, and the speaker notes. Microsoft brought it with PowerPoint 2007 to replace PPT, as part of the Office Open XML standard. PPTM holds macros, POTX and POTM are templates, and PPSX and PPSM are saved to open as a show.
Decks travel by email and chat more than any other office file, and they carry more than their slides: speaker notes, hidden slides, the author's name, and macros in a PPTM.
Filepeek reads the deck itself and draws each slide with its theme, fonts, pictures, shapes, tables and charts. See them as Slides, as a Grid, with their Notes or as an Outline of their text, and Present them full screen with their transitions and builds. Macros never run.

Questions
How do I open a PPTX file without PowerPoint?
Drop it on this page or choose Peek a PPTX. It opens at its first slide, with every slide beside it.
Can I present it?
Yes. Choose Present for a full screen show with the deck's transitions and builds. The arrow keys, a click or a tap move it on, and Escape ends it.
Can I see the speaker notes?
Yes. Notes shows each slide with its notes under it, and Export saves all of them as text.
Can I save it as a PDF?
Yes. Choose Export, then Save as PDF, and every slide goes on a page of its own. Save as PNG or JPEG saves slides as pictures.
Can it open a deck with a password?
Yes. Type the password when Filepeek asks, and it opens. The password stays on your device, and it's gone once you close the file.
Is my file uploaded?
No. The deck opens inside your browser and never leaves your device.
