PPSX to HTML conversion is the process of transforming a Microsoft PowerPoint Slide Show file (PPSX) into standard web pages (HTML) so slides and their content can be viewed in a browser without PowerPoint. The conversion extracts slide layouts, text, images, and simple animations/transitions where possible and wraps them in HTML, CSS, and often JavaScript for interactive playback.

PPSX files use the MIME type application/vnd.openxmlformats-officedocument.presentationml.slideshow and contain slide show data with embedded multimedia codecs. HTML files use the MIME type text/html and represent structured web content with support for CSS and JavaScript. Converting PPSX to HTML involves extracting slide content and rendering it into web-compatible code.
The HTML (.HTML) format is commonly used for presentation. Understanding its characteristics can be helpful when converting to or from other formats like PPSX.

PPSX files are Microsoft PowerPoint Slide Show files designed for presentation software, typically requiring PowerPoint to view. HTML is a web-native format that can be displayed on any modern browser without additional plugins. Unlike PPSX, HTML files are more flexible and accessible across various devices and platforms.
Keep individual PPSX files under 100–200 MB for faster, more reliable conversions; very large files increase processing time and may require splitting into smaller projects.
To preserve visual fidelity, use the highest slide export resolution and choose lossless or low-compression image settings; embed fonts or use web-font substitutes to maintain typography.
For many slides, prefer multi-file HTML output (separate assets) to reduce initial load time and allow lazy-loading of images or video.
Batch conversion is supported by most professional tools or APIs—prepare consistent template slides and test one file first to confirm formatting before converting a large batch.
