10 Best Free Alternatives to Microsoft Office (2026)

Microsoft Office remains the industry standard for document creation, but its subscription pricing ($99.99/year for Microsoft 365 Personal), license restrictions, and Windows/Mac-only availability drive users toward free alternatives. Whether you need perfect DOCX compatibility, cloud collaboration, or a lightweight offline suite, there are mature options that handle everything from spreadsheets to presentations.

LibreOffice is the most established free office suite, forked from OpenOffice in 2010 and developed by The Document Foundation.
