Looking for a free Microsoft Office alternative for Windows 10 or 11? Meet Xrero Office — four full apps, one free download, no subscription.
What you get in one free install
- Writer — a full word processor that opens and saves Word .docx
- Calc — spreadsheets with formulas and charts, compatible with Excel .xlsx
- Slides — presentations that open and save PowerPoint .pptx
- PDF — a reader and editor that can convert PDF to Word
How it compares to Microsoft 365
Microsoft 365 charges a monthly subscription and pushes you to the cloud. Xrero Office is 100% free, installs on your PC and works completely offline — while opening the same file formats your colleagues send you.
Arabic support that actually works
Unlike most alternatives, Xrero Office was built Arabic-first: proper right-to-left text, Arabic fonts and a full Arabic interface — alongside English — make it the natural choice in the UAE and across the Arab world.
Free means free
Xrero Office is open-source (AGPL). No trials, no locked features, no ads. Download it once and use it forever.
FAQ
Is Xrero Office compatible with Microsoft Office files?
Yes — .docx, .xlsx and .pptx open and save natively, plus the older .doc, .xls and .ppt formats.
Does it run on Windows 11?
Yes, Windows 10 and 11 (64-bit) are both supported.
Is there a catch?
No. The suite is open-source software — free is the license, not a promotion.
