Host a PowerPoint file and share it as a link
Put a .pptx deck online at its own address so people can download the current version — without a 40 MB attachment bouncing back.

Any other file works too — up to 25.0 MB, or 100.0 MB for a whole site
Free to use. Your PPTX file is live at your-name.99helpers.site in about ten seconds.
What is a .pptx file?
PPTX is the PowerPoint format introduced with Office 2007, replacing the older binary .ppt. It's a ZIP archive of XML describing each slide, its layout, animations and embedded media — which is why decks with video in them get so large so quickly.
What people use PPTX files for
- Pitch decks sent to investors or prospects
- Training material and internal presentations
- Conference talks shared with attendees afterwards
- Templates colleagues build their own decks from
- Client-facing proposals and quarterly reviews
What opens a PPTX file
- Microsoft PowerPoint on desktop, web and mobile
- Google Slides, which imports and exports .pptx
- Apple Keynote and LibreOffice Impress
- Most conference and webinar platforms, as an upload format
How to host a PPTX file
- 1
Drop your PPTX file in
Drag it onto the box at the top of this page, or click to choose it. Files up to 25 MB are supported, and nothing is uploaded until you publish.
- 2
Pick an address
Type a name and we'll tell you straight away whether it's free. That becomes the link: pitch-deck.99helpers.site
- 3
Publish and share
Create a free account — that step exists so the file is yours to update, replace or delete — and the link is live within seconds.
The same three steps work for any file — see how file hosting works on 99helpers.com.
What happens when someone opens the link
The deck downloads and opens in PowerPoint or whatever presentation software the reader uses. Browsers don't render .pptx in place, so this is standard behaviour across the web.
Why host a PPTX file instead of emailing it?
Decks are among the largest files people routinely email, and they're revised constantly — which means a mailbox full of near-identical attachments and no way to tell which is current. One address that always holds the latest version solves both problems at once.
Worth knowing before you publish
- Embedded video is usually what pushes a deck over the size limit; linking to a hosted MP4 instead keeps the file small.
- Export to PDF as well if people only need to read it — a PDF opens in the browser instantly and can't be accidentally edited.
- Speaker notes travel inside the file, so check them before sharing a deck outside your team.
- PowerPoint's Compress Pictures option often halves a deck's size with no visible difference.
PPTX hosting questions
- Can people view a PowerPoint in the browser?
- Not directly — no browser renders .pptx, so it downloads and opens in PowerPoint, Slides or Keynote. If in-browser viewing matters, export the deck to PDF and host that: it opens instantly with nothing to install.
- How do I send a large PowerPoint file?
- Upload it here and share the address. There's no attachment limit to work around and nothing for the recipient to sign into. Files up to 25 MB are supported, which covers most decks once video is linked rather than embedded.
- Will animations and transitions still work?
- Yes. The file is served exactly as uploaded, so opening it is identical to opening your original — animations, transitions, fonts and embedded media all intact.
- Can I update the deck after sending the link?
- Publish the new version to the same address. Everyone who has the link now gets the current deck, and earlier versions are kept in case you need to roll back.
