Free Alternatives to Microsoft Office
You don't need to pay for Office to write documents, build spreadsheets or make presentations — these free alternatives cover the vast majority of everyday needs.
| Alternative | Stands out for |
|---|---|
| LibreOffice | The most complete and compatible, works offline |
| Google Docs/Sheets/Slides | Real-time collaboration, everything in the cloud |
| OnlyOffice | Interface closest to classic Office |
LibreOffice: the most complete offline option
Free, open source, installs on your machine and works without internet. Compatible with most .docx, .xlsx, .pptx files, though very complex documents with advanced Office formatting can show small visual differences when opened.
Google Docs/Sheets/Slides: the best for collaborating
Everything runs from the browser, with automatic cloud saving and real-time collaboration with other people — ideal if you regularly work on shared documents.
A note on compatibility: when collaborating with someone using real Office, documents with very advanced formatting (complex macros, certain Excel-specific formulas) may not transfer perfectly between different programs — for normal use this is rarely a noticeable problem.
Tip: if you only need basic office work (documents, spreadsheets, simple presentations), any of these alternatives covers the need perfectly at no cost at all.
