You've received a .pptx file but don't have PowerPoint installed. Or you need to share slides as a PDF so recipients can't accidentally edit them. Either way, you don't need to install anything — a browser is all it takes.

Step-by-Step: PPTX to PDF

1. Open the PPT to PDF tool.
2. Drag and drop your .pptx file onto the upload area.
3. The tool parses the slide XML and renders each slide as a PDF page using HTML/CSS layout.
4. Download the resulting PDF.

What's Supported and What Isn't

Because this tool renders slides in a browser (not inside PowerPoint's rendering engine), some features work differently:

Feature	Status
Text content	✅ Supported
Embedded images	✅ Supported
Basic shapes and colours	✅ Supported
Custom fonts	⚠️ Substituted with system fonts
Animations and transitions	❌ Not supported (static output)
Embedded charts and SmartArt	❌ Not supported
Video/audio embeds	❌ Not supported

Best results: presentations with text, images, and simple shapes. Complex design-heavy decks with custom fonts and charts will render approximately but not pixel-perfect.

For Pixel-Perfect Conversion

If you need an exact match to how PowerPoint renders the slides, the most reliable method is: open the file in LibreOffice Impress (free), then export as PDF using File → Export as PDF. This uses the same rendering engine that handles all Office format quirks.

Frequently Asked Questions

Is my file uploaded to a server?

No. The tool parses the PPTX file locally using JavaScript. Nothing is sent to any server.

Why do my custom fonts look different?

Custom fonts (e.g., proprietary corporate fonts) are not embedded in PPTX files and can't be loaded by a browser without the font file. The tool substitutes a matching system sans-serif font.

What's the maximum file size?

There's no server-side limit. Very large presentations (100+ slides with high-res images) may be slow depending on your device's memory.
