Free PowerPoint Alternative — Online Presentation Maker
A complete PowerPoint-class presentation editor that runs entirely in your browser: master slides, themes, transitions, speaker notes, and real .pptx files. Nothing is uploaded — your decks stay on your own device.
DeckCraft
Build slide decks with layouts, themes, and presenter view - PowerPoint-class, in your browser.
First launch downloads ≈9 MB, then it's cached for a year. Nothing is uploaded — your files stay on this device.
This is a desktop-class app — it works best on a larger screen.
Quick Answer
This free online presentation editor gives you the core PowerPoint workflow in a browser tab: master slides and layouts, themes, text, images, shapes, tables, slide transitions, speaker notes, and a presenter view. It opens and saves real PowerPoint .pptx files that round-trip with desktop PowerPoint. The editor is a WebAssembly application that runs on your device — decks are never uploaded to any server.
How It Works
Open and Launch — Open the deck creator page in a desktop browser and click Launch. The first launch downloads about 9 MB; after that it is cached.
Open or Start a Deck — Open an existing .pptx through the file picker, or start from a blank deck with a theme.
Build Slides — Lay out text, images, shapes, and tables on slides; add transitions and write speaker notes.
Present and Save — Use presenter view to rehearse, then save the deck as .pptx to your device — it opens directly in PowerPoint.

Frequently Asked Questions
Is this really free, and do I need an account?
Yes — completely free, no account, no watermarks. The underlying software is open source under Apache-2.0, embedded exactly as published.
Are my presentations uploaded anywhere?
No. The whole editor runs as WebAssembly inside your browser tab; slide design, rendering, and saving all happen on your device.
Does it work with real PowerPoint files?
Yes — it opens .pptx decks with layouts, media, and notes, and saves .pptx desktop PowerPoint reads. Very exotic PowerPoint features (VBA macros, some add-ins) are not supported.
Can I present full-screen with speaker notes?
Yes — presenter view gives you the current slide, next slide, and your notes, while the audience sees only the slide.
Does it work on mobile?
It runs on modern mobile browsers, but building slides wants a desktop screen and a pointer. For phone use, export your deck to PDF and present from any viewer.
