PPTX and PPT support
Convert modern PowerPoint presentations and legacy PPT files into PDF documents.
PowerPoint to PDF API
Convert Microsoft PowerPoint presentations into PDF files using a REST API.
Convert modern PPTX and legacy PPT presentations using LibreOffice, through a persistent conversion engine.
Key features
LibreOffice conversion engine
Use a persistent LibreOffice engine to render presentation slides into PDF pages.
Supported PowerPoint formats
PPTX
Modern Microsoft PowerPoint presentations based on the Office Open XML format.
PPT
Legacy Microsoft PowerPoint presentations supported through LibreOffice conversion.
Presentation rendering
The API uses LibreOffice to render presentation slides into PDF pages, preserving the slide content and layout as closely as possible.
Presentation content
Standard presentation elements such as text, images, shapes, tables and charts can be rendered into the resulting PDF.
Slide layout
Slide dimensions and orientation are retained during conversion, without forcing a standard paper size such as A4.
License and evaluation
The API is available to Free users for evaluation. Generated PDFs include a permanently embedded evaluation watermark on every page. A Basic license or higher is required to generate PDFs without this watermark.
Use cases
- Convert business presentations into PDF documents.
- Share presentations in a widely supported, read-only document format.
- Archive presentation content in PDF format.

Successful response

Important considerations
- Missing fonts may be substituted and can affect text positioning or slide layout.
- Animations and slide transitions are not preserved as interactive effects in PDF files.
- Audio and video content cannot be reproduced as interactive media in a standard PDF.
- Verify the output when presentations contain complex layouts, charts or embedded objects.
- File processing and request limits apply.
