Comparison
A free alternative to Microsoft PowerPoint, with no account and no upload
Need to touch up or present a PowerPoint presentation (.pptx) without a licence, without an account, or without putting confidential slides online? Here is how ElniDocs compares with the most widely used presentation software.
In short
ElniDocs is a free presentation editor that opens and saves PowerPoint files (.pptx) in the browser, with slides, images, tables, charts, transitions, animations and presenter view. No account, no installation, and the file stays on your device. PowerPoint for the web and Google Slides require an account and store your presentations in their cloud; LibreOffice Impress works locally but has to be installed.

Comparison made on October 19, 2026 from each product's public pages. Their offers may change: check them on their websites.
When ElniDocs is the better choice
- The presentation is confidential (results, strategy, a client project) and must not leave your computer.
- You need to fix a slide just before a meeting, on a computer without PowerPoint.
- You present without a reliable connection: once loaded, ElniDocs works offline, presenter view included.
- You want neither a subscription nor an account for an occasional presentation.
When another tool is a better fit
- Several people prepare the slides at the same time: PowerPoint for the web and Google Slides do it live.
- You need advanced features (add-ins, recording the slideshow with narration): desktop PowerPoint goes further.
- You want your presentations on all your devices without doing anything: Microsoft's or Google's cloud takes care of it.
Switching to ElniDocs
- Open the ElniDocs editor for PowerPoint files: nothing to install, no account.
- Drop your .pptx file, or create a blank presentation.
- Edit your slides, present full screen, then save as .pptx or PDF.
Frequently asked questions
Will the .pptx file then open in PowerPoint?
Yes: it opens without needing repair, with its slides, notes, transitions and animations.
Can I present with my notes?
Yes: presenter view shows your notes, the next slide and the elapsed time, while the audience sees the slide full screen.
Is ElniDocs really free?
Yes: every feature is free, with no subscription, no adverts and no watermark. ElniDocs has no server processing your presentations: your device does the work.
