No subscription, no internet required — here is how to open .docx, .xlsx and .pptx files for free.
The easy way: install one free suite
If you regularly receive Word (.docx), Excel (.xlsx) and PowerPoint (.pptx) files, the simplest solution is to install one free suite that opens all of them. Xrero Office does exactly that — four apps, one free download, and it works completely offline.
Step by step
- Download Xrero Office free from xrero.com/office and run the installer on Windows 10 or 11.
- Create your free account once (email or Google) — this activates the apps and you are never asked again.
- Double-click any file. A .docx opens in Writer, an .xlsx in Calc, a .pptx in Slides, and PDFs in the built-in reader.
- Edit and save back to the same format, or export to PDF. You are offline the whole time.
Why offline matters
Working offline keeps your documents private — they never leave your computer — and means you can open and edit files on a flight, in a meeting room with no Wi-Fi, or anywhere the connection is unreliable. There is no cloud lock-in and no monthly fee.
It is free, and it is for everyone
Xrero Office is 100% free because opening and editing your own documents should not cost a subscription. It is built to help everyone — students, freelancers, small businesses and large teams — with first-class Arabic and right-to-left support for the UAE and the wider region.
Free, offline, and built to help everyone
Xrero Office exists for one reason: everyone should be able to open, edit and share documents without paying for a subscription. It is 100% free, it runs offline on your own Windows PC, and it treats Arabic and right-to-left as a first language. There is no trial, no credit card and no paywall — just download it, create a free account once, and start working.
