Convert PPTX to HTML
Updated Jul 2026
PPTX is the file format PowerPoint saves presentations in, and HTML is the format every web browser reads. To convert PPTX to HTML, open the file in a converter and export each slide as a web page. Doing it on your own computer means the slides, and anything written in your speaker notes, never have to leave your machine.

How to convert PPTX to HTML
- Open Morphjet and drag in the PPTX file you want to convert, or a whole folder of decks at once.
- Choose HTML as the output format.
- Convert. Morphjet writes a set of web pages next to your original file, with the slide images, text, and layout carried over, and nothing leaves your machine.
PPTX vs HTML: what actually changes
| PPTX | HTML | |
|---|---|---|
| Opens everywhere | No, needs PowerPoint or a compatible viewer | Yes, opens in any web browser |
| File size | Compact, even with many slides | Larger, especially if images are embedded in the page |
| Editable as a slideshow | Yes, fully editable in PowerPoint | No, becomes static web content, not something you present from |
| Animations and transitions | Yes, supported | No, most are lost in the export |
| Speaker notes | Yes, kept alongside the slides | Not shown by default, unless included as page text |
When to convert, and when not to
Convert PPTX to HTML when you want to publish a presentation on a website, embed it in a blog post, or let people view it in a browser without opening PowerPoint or a separate viewer.
Keep the original PPTX if you still need to edit the deck, present it live with its animations, or rely on the speaker notes, since none of that survives the trip to HTML.
Why not just use an online converter?
A slide deck can hold sensitive information, client names, financial figures, unreleased plans, even in speaker notes nobody sees on screen. Uploading it to an online converter site sends every slide and every note to that site's servers. Converting on your own computer keeps the presentation, and everything written into it, on your machine the whole time.
Questions
Does converting PPTX to HTML keep the formatting?
The layout, text, images, and fonts on each slide are generally preserved, but animations, transitions, and embedded video won't carry over, since a web page doesn't play them the way PowerPoint does.
Can I still edit the presentation after converting to HTML?
Not as a slideshow. The output is a set of web pages, so from that point you'd edit it like a website, not by rearranging slides in PowerPoint.
Do speaker notes come through in the HTML?
Not automatically. Speaker notes usually stay behind in the PPTX unless the converter is set to include them as visible text on the page.
Can I convert PPTX to HTML without uploading the file?
Yes. Morphjet converts on your own computer, so the slides and any notes in them never travel over the internet.
Morphjet converts PPTX, HTML, and 1,800+ other formats, all on your machine. Launching this July.
