A complete, 100% free office suite that opens Word, Excel and PowerPoint files — and works offline.
What is Xrero Office?
Xrero Office is a free office suite for Windows 10 and 11 and a genuine Microsoft Office alternative. It bundles four familiar apps — Xrero Writer (documents), Xrero Calc (spreadsheets), Xrero Slides (presentations) and a built-in PDF reader — and it opens and saves the exact same files you already use: .docx, .xlsx, .pptx and .pdf.
Unlike Microsoft 365, there is no monthly fee and no online-only editor. Xrero Office installs on your computer and runs offline, so your documents stay on your machine. It is 100% free — forever.
Why choose a free Microsoft Office alternative?
Microsoft Office is powerful, but for most people it is also expensive and increasingly subscription-only. If you just need to write a letter, build a budget, open a client’s PowerPoint, or read and sign a PDF, you should not have to pay every month. Xrero Office gives you those everyday tools for nothing, with the ribbon and shortcuts you already know.

Open Word, Excel and PowerPoint files — no conversion
Xrero Office is format-compatible, not format-locked. Double-click a Word .docx, an Excel .xlsx or a PowerPoint .pptx and it opens straight away, keeping your layout, fonts, tables and charts. Save back to the same format so colleagues and clients on Microsoft Office see exactly what you see. You can even turn a PDF into an editable Word document in one click.
Works offline, with first-class Arabic
Everything runs locally on your PC, so you can work on a plane, in a cafe with no Wi-Fi, or anywhere privacy matters — your files never have to leave your computer. Xrero Office is also built for the UAE and the wider Arabic-speaking world: every app flips between English and Arabic in one click, with correct right-to-left layout throughout.
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.
