This free PowerPoint to HTML converter extracts the text and images from a .pptx presentation into a clean, self-contained HTML document — entirely in your browser, so your slides are never uploaded. Use it to publish slide content on the web, feed a deck into a CMS or LLM, or simply get the text out of a presentation.
How it works
A .pptx file is a zip archive of XML parts. The tool unzips it locally, reads each slide's XML, and maps the content to semantic HTML:
| Slide content | Becomes |
|---|---|
| Title placeholder | <h1> (first slide) / <h2> (other slides) |
| Text box with one paragraph | <p> |
| Text box with several paragraphs | <ul> with one <li> per paragraph |
| Pictures | <img> embedded as a data URL |
| Each slide | One <section class="slide"> |
The output is a structural extraction, not a pixel-perfect rendering: animations, exact positioning, and theme styling are not reproduced.
Steps
- Drop a PowerPoint (.pptx) file, or click to choose one — it is parsed locally, nothing is uploaded.
- Review the generated HTML source and the slide/image counts.
- Download the .html file, copy the source, or open a rendered preview in a new tab.
Example
A 2-slide deck ("Q3 results" with three bullets, "Q4 plan" with a chart image) becomes:
<section class="slide">
<h1>Q3 results</h1>
<ul>
<li>Revenue grew 12% QoQ</li>
<li>New enterprise deals: 8</li>
<li>Churn down to 1.9%</li>
</ul>
</section>
<section class="slide">
<h2>Q4 plan</h2>
<img src="data:image/png;base64,…" alt="" />
</section>
When to use PowerPoint to HTML
- Publishing slide content as a web page or blog post without retyping it.
- Extracting a deck's text for translation, search indexing, or LLM processing.
- Archiving presentations in a format every browser can open.
Limitations
- Only .pptx (the modern format) is supported — legacy .ppt files are not.
- SmartArt, charts, and tables are not fully extracted; charts appear only if the deck stores them as images.
- Images are embedded as base64 data URLs, so image-heavy decks produce large HTML files.
