Convert PPTX to PDF Over One API Call
python-pptx can't export PDF — it's a file-format library, not a renderer. The usual workarounds are PowerPoint COM automation or babysitting LibreOffice yourself. Now it's one HTTP call.

The PowerPoint Engine MCP server grew from 3 tools to 8: replace text in an existing deck, do slide surgery, merge presentations, convert to PDF and translate — all chainable in one agent conversation.
Markdown Tables and Combo Charts, Natively in PowerPoint
A markdown table becomes a styled, editable PowerPoint table. A combo chart with a secondary axis takes five lines. No python-pptx XML archaeology required.
Slide Surgery: What python-pptx Can't Do, Over One API Call
Duplicate, delete and reorder slides in an existing .pptx — the three oldest open python-pptx feature requests — now one HTTP call. Formatting untouched.
"How do I convert a .pptx to PDF in Python?" is one of the most-asked python-pptx questions, and the answer has been the same for a decade: you can't. python-pptx reads and writes the file format; it does not render slides, and the maintainer has been clear that rendering is out of scope. Every StackOverflow thread ends in one of two workarounds — and both hurt.
The two painful workarounds
- PowerPoint COM automation (comtypes / win32com): perfect fidelity, but you need a Windows machine with a licensed PowerPoint installed — a non-starter on Linux servers, Docker, or any serverless platform.
- LibreOffice headless: works on Linux, but now you own a ~700MB install, font packages, a user-profile lock that corrupts under concurrent requests, and a process that occasionally hangs and eats a CPU core forever.
Either way, the "simple" conversion becomes a piece of infrastructure you maintain.
One call instead
Upload any .pptx — one you generated with our API or one you already had — and get a download link for the PDF back:
curl -X POST https://powerpointengine.io/api/powerpoint/pdf \
-F "file=@quarterly-review.pptx"The response is JSON with a signed URL:
{
"success": true,
"result": {
"filename": "quarterly-review_1784024726358.pdf",
"downloadUrl": "https://storage.googleapis.com/...",
"fileSize": 26122,
"expiresAt": "2026-07-15T12:25:28.000Z"
}
}A typical deck converts in a couple of seconds. Behind the API we run the LibreOffice fleet for you — isolated per-request profiles, serialized conversions, hung-process timeouts — so none of that operational mess reaches your code.
Generate, then ship the PDF
This closes the loop for automated reporting: generate a deck from Markdown (tables and charts included), then convert it to PDF for email attachments, customer portals, or archives — two calls, no Windows box, no LibreOffice babysitting. See the API docs or the agent skill for details.
