What is PPT to HTML?
PPT to HTML conversion turns a PowerPoint presentation into a self-contained web viewer. It reconstructs slide text, shapes, images, layering, and supported media with HTML, CSS, SVG, and browser JavaScript, so viewers do not need PowerPoint.
Source
PPTX
Slides, text, images, shapes, and layout information.
Browser-ready output
HTML package
A ZIP containing a self-contained index.html file and license notice, ready to open locally or upload to a web host.
The goal is faithful translation, not redesign. The original composition stays recognizable while the viewer and controls adapt to desktop, tablet, and mobile screens.
Visual fidelity
Review the original, then inspect the generated HTML.
The converter maps slide dimensions, selectable text, shapes, images, and layering into browser DOM and SVG. Both previews show the same slide, so you can review the source first and the HTML immediately after it.

Common animation cues, slide transitions, embedded audio, and browser-compatible video are retained when possible. Autoplay rules, codecs, missing fonts, macros, 3D objects, and uncommon PowerPoint effects may require a fallback.
Built around the result that matters.
A focused PPT to HTML workflow for people who need presentations to stay recognizable in a browser without rebuilding every slide by hand.
02
Work on mobile
Give viewers a readable, touch-friendly experience instead of shrinking a desktop canvas into a phone.
03
Stay in control
Upload, convert, inspect, and download in one predictable flow with specific progress and recovery states.
04
Protect the file
Require sign-in, keep the source PPTX in the browser, and restrict generated previews and downloads to the file owner.
Complete a PPT to HTML conversion in three steps.
The workflow stays familiar at every screen size, with no special knowledge of PowerPoint internals or web code required.
- 1
Upload the source
Choose a PPTX file up to 30 MB on desktop or 10 MB on mobile, then sign in to continue. The browser validates the file before processing.
- 2
Follow the conversion
See the current stage and percentage while a dedicated browser worker converts the deck. Presentations with more than 100 slides stop with a clear error.
- 3
Review and download
Preview the browser-rendered output and read any fidelity notes. Then download the self-contained HTML ZIP or create an optional share link you can disable at any time.
Mobile is a first-class output
A presentation that remains usable away from the desktop.
The generated viewer adapts navigation and slide framing for narrow screens while keeping the original composition recognizable.
- Touch targets remain comfortable and clear.
- Slide content scales without horizontal page scrolling.
- The same slide order and fidelity notes follow the viewer.

Privacy and honest limits
Know what happens to the file—and where fidelity can change.
Trust comes from specific handling rules and clear fallback notes, not from vague claims about perfect conversion.
Protected in transit
Preview and download requests require a signed-in account and are checked against the file owner.
Source stays in the browser
The source PPTX is not uploaded separately. Generated HTML previews and ZIP packages remain private and are deleted automatically after 3 days.
Private until you choose to share
PPT to HTML conversions stay private to the account owner unless they create a share link. Anyone with an active link can view it; links can be disabled at any time and are not indexed by default.
Questions before you convert
Straight answers about fidelity, mobile output, file support, privacy, and whether AI is required.
Not for every deck. The converter aims for the highest practical visual fidelity and retains common animations, transitions, audio, and browser-compatible video when possible. Fonts, codecs, macros, 3D objects, and uncommon PowerPoint effects may render differently.
Bring one presentation. Leave with browser-ready HTML.
Sign in to upload a presentation, review the converted result and fidelity notes, then download the HTML package or create an optional share link.
