Slides used to mean a PowerPoint PPTX file. Now an AI agent can build a whole deck as one HTML file in a minute, and it opens in any browser. HTML and PPTX both have their place. Here is how they compare, with a live HTML deck below so you can feel the difference.
Click through an HTML deck
This deck is one HTML file. Use the arrows or your keyboard, and try the sliders on slide four.
HTML vs PPTX, side by side
- Opening it. A PPTX file needs PowerPoint, Keynote, or a converter, and fonts can change on the way. An HTML deck opens in any browser, exactly as it was designed.
- Phones. A PPTX on a phone means pinching and zooming. An HTML deck can lay itself out for a small screen.
- Sharing. A PPTX is an attachment, and every fix means sending a new one. An HTML deck is a link, so everyone always sees the latest version.
- Interactive. Charts in a PPTX are pictures of data. An HTML deck can hold live charts, calculators, video, and anything else a web page can do.
- Made with AI. Agents like Claude and ChatGPT write HTML natively, so the deck comes out finished. A PPTX needs extra tooling to generate, and layouts often break.
- Knowing who saw it. There is no telling whether anyone opened a PPTX attachment. A hosted HTML deck can show you views and visitors.
When a PPTX is still the right call
- Someone has to edit it by hand. If a client will change the slides themselves in PowerPoint, send PowerPoint.
- Your company template is a PPTX. Brand teams often ship a PowerPoint master, and some review processes expect one.
- Presenting with no internet. A PPTX runs fully offline in PowerPoint, with presenter notes built in.
Host your HTML deck on DocStash
An HTML deck needs somewhere to live, or it is just another file to attach. DocStash is a home for the pages your AI makes. Your deck gets one link you can present from and send around, it starts private, and every fix shows up at the same link, no new PPTX to email. Drop in a deck you already have, or connect your agent and let it stash the deck for you.
Already have the HTML?
- Drop the file below. Drag it anywhere on this page, or choose it. It becomes a webpage with its own link, private until you publish it.htmlmdtextpdf
- Share it. Click Publish for a public link, or share it with specific people.
Make and share an HTML deck
- Ask your agent for a deck. Say "make a six slide HTML presentation of our Q3 results as one file". Claude, ChatGPT, and Cursor all do this well.
- Stash it to DocStash. Connect your agent and ask it to stash the deck. You get one link like
docstash.ai/<slug>, private until you share it. - Present from the link. Open it full screen in any browser. Click Publish for anyone with the link, or share it with certain people.
- Fix it without resending. Ask for changes and stash again. The same link shows the new version, and every earlier version stays in Activity.
FAQ
Can I convert an HTML presentation to PPTX?
Not cleanly. Live charts and controls have no PowerPoint equivalent. If someone needs a PPTX, ask your agent for one separately.
Can I present an HTML deck full screen?
Yes. Open the link and switch your browser to full screen. In most decks the arrow keys move between slides.
Will an HTML deck look the same for everyone?
Yes, as long as it loads its fonts from the web. Every modern browser shows the same page.
Can I see who opened my deck?
On DocStash Pro, analytics shows views, visitors, and where they came from for published pages.
Is it safe to share a deck as a link?
On DocStash a deck starts private. Share it with specific people, or publish it for anyone with the link. Published pages always stay out of search.
Is HTML better than PPTX for presentations?
For decks you share as a link, view on phones, or build with AI, yes. HTML opens anywhere and stays up to date. A PPTX is still better when someone needs to edit the slides in PowerPoint or present fully offline.
Your next deck, as a link
Connect your agent to DocStash and present from a link that is always up to date.
