## Overview

This PPSX viewer renders PowerPoint slide-show files locally in your browser. These formats always open in presentation mode rather than the editor. Pick a sample or choose your own .ppsx or .ppsm file to flip through slides without PowerPoint installed.

## When to use

- You received a .ppsx slide show and only need to read or present it.
- You want to preview a self-running presentation before opening it in PowerPoint.
- You are on a device without PowerPoint and need to view a slide show.

## How it works

- Select a built-in sample or choose your own .ppsx or .ppsm file.
- The viewer parses the slide-show format and renders each slide in the browser with no upload.
- Navigate between slides and read the content, then switch samples or load another file any time.

## Use cases

- Reviewing self-running kiosk or training slide shows.
- Previewing a macro-enabled slide show (.ppsm) in a safer read-only view.
- Presenting from a device that does not have PowerPoint installed.

## Samples

- **Simple PPSX Slide Show**: Lightweight slide-show deck that opens directly in presentation mode
- **Business PPSX Deck**: Business-style slide show with metrics, table, and structured content
- **Feature Showcase PPSX**: Feature-focused slide show demonstrating product highlights and workflow

## Frequently asked questions

### Is this PPSX viewer free?

Yes. It runs in your browser for free and needs no account or installation.

### Are my .ppsx files uploaded?

No. Files opened from your device stay on your device. Only public sample files come from the server.

### What is the difference between PPSX and PPTX?

.ppsx always opens in slide-show (presentation) mode, while .pptx opens in the editor. This viewer focuses on the slide-show format.

### Do animations and transitions play?

Static slide content, text, and images render faithfully. Complex animations may be simplified compared to desktop PowerPoint.
