PPTX to HTML
Turn PowerPoint slide content into semantic HTML for inspection, archiving, and structured workflows. The same local workspace also exposes Markdown and JSON previews in the downloadable LLM package.
This page opens the HTML preview by default. Download ZIP always includes the same complete package: Markdown, HTML, JSON, manifest, and assets.
Local conversion flow
Upload a PPTX file, convert locally, preview the result, then download the ZIP.
Files stay in the browser. The worker generates a ZIP package locally.
Upload a PPTX file, then run the matched converter.
Preview panel
Inspect Markdown, HTML, or JSON before downloading.
Convert a PPTX file to inspect Markdown, HTML, and JSON output. After conversion, view full details in the Details workspace.
Details workspace
Opened after conversion for slide structure, previews, files, and warnings.
Convert a PPTX to unlock details
After conversion, View details expands slide structure, Markdown/HTML/JSON preview, package files, and warnings.
What the HTML includes
The generated `index.html` uses semantic sections for slides and includes paragraphs, lists, tables, chart data, speaker notes, shape text, and content images where available.
Why HTML helps review
HTML is useful when you want a human-readable local preview before sending Markdown or JSON to an LLM, agent, or downstream automation.
Privacy boundary
PPTX files are processed in the browser by default. Images and HTML are packaged into the local ZIP without requiring a server conversion step.
