Microsoft Office is the standard, but it is not the only choice. If you need to write documents, build spreadsheets or make presentations, there are good free options. Here is how they compare and who each one suits.
LibreOffice
A free, open-source office suite that installs on your computer. It includes Writer, Calc and Impress, which cover Word, Excel and PowerPoint tasks. It works offline and opens most Microsoft file formats. Complex documents and macros may look slightly different, so test your important files.
Google Docs, Sheets and Slides
Free with a Google account and run in your browser. Very good for real-time collaboration and sharing. They convert Microsoft files, and you can download your work as Word, Excel or PowerPoint formats. Businesses that want a custom email domain and admin controls can upgrade to Google Workspace.
Microsoft 365 for the web
Microsoft offers free browser versions of Word, Excel and PowerPoint with a Microsoft account. They have fewer features than the desktop apps but are fully compatible with Office files.
OnlyOffice
A free desktop suite with an interface similar to Microsoft Office. It is known for good compatibility with Office formats.
Which should you pick?
- Working with clients who send Office files: try Microsoft 365 for the web or OnlyOffice first.
- Teams that edit together: Google Docs or a paid Workspace plan.
- Offline work and no account needed: LibreOffice.
When free is not enough
Paid plans make sense when you need shared business email, admin and security controls, large storage or support. See our Microsoft 365 vs Google Workspace comparison.
Frequently asked questions
Are free office suites legal for business use?
LibreOffice and OnlyOffice’s free desktop editions can be used by businesses under their licences. Check the licence terms on the official sites. Free Google and Microsoft web apps are intended for individuals, and businesses should review each provider’s terms.
Will my documents look the same?
Simple documents usually do. Complex layouts, fonts and macros can change, so test important files before you switch.
Should I use a cracked or cheap licence key instead?
No. Unofficial keys can be illegal and are a common route for malware. Use a free alternative or buy from an authorised seller.
