LibreOffice is a free, open-source office suite that provides powerful alternatives to Microsoft Office applications. Developed by The Document Foundation, LibreOffice includes Writer (word processing), Calc (spreadsheets), Impress (presentations), Draw (vector graphics), Base (databases), and Math (formula editing).
Writer handles complex documents with styles, tables of contents, references, bibliographies, and mail merge. Document compatibility with Microsoft Word formats (.doc, .docx) ensures seamless collaboration. The built-in PDF export creates professional documents directly.
Calc provides spreadsheet functionality with over 500 functions, pivot tables, conditional formatting, and data validation. Charts and graphs visualize data effectively. Solver handles complex optimization problems. Calc reads and writes Excel formats maintaining formulas and formatting.
Impress creates engaging presentations with transitions, animations, and multimedia embedding. Master slides ensure consistent formatting. Presenter console displays notes and upcoming slides during presentations. PowerPoint compatibility enables sharing with Microsoft Office users.
Draw handles diagrams, flowcharts, and vector graphics. Base provides database management with connections to MySQL, PostgreSQL, and other database systems. Math creates complex mathematical formulas using markup language.
LibreOffice includes extensive language support with grammar checking for many languages. The extension manager adds features through a large plugin repository. Regular updates bring new features and security improvements. The portable version runs from USB drives. Cross-platform availability means documents remain consistent across Windows, macOS, and Linux.
