LibreOffice
An open-source office suite for Windows, macOS and Linux that includes Writer, Calc, Impress, Draw, Base and Math and works with ODF and common Office files.
What LibreOffice includes
LibreOffice provides Writer for documents, Calc for spreadsheets, Impress for presentations, Draw for diagrams, Base for database work and Math for formulas. Its native OpenDocument formats preserve editable structure, while Office formats and PDF are useful for collaboration and fixed-layout delivery.
Compatibility should be tested
DOCX, XLSX and PPTX files can open successfully while still changing complex fonts, page breaks, charts, macros, formulas or animations. Keep the original file, save an ODF working copy when appropriate, and reopen any important delivery in the software used by the recipient.
Macro and data boundaries
Macros are executable automation, not ordinary document text. Keep macros disabled for unfamiliar files and inspect the sender, purpose and file contents before enabling anything. Font availability, locale settings and external links can also change calculation and layout results.

LibreOffice editing, compatibility and PDF export
Use a disposable test document to confirm fonts, locale settings and the intended save format. Keep an editable source and create delivery copies for Office or PDF.
Before you start
- Prepare test files without sensitive information and keep their original copies.
- Decide whether the recipient needs ODF, an Office format or fixed-layout PDF.
- Install the fonts used by the source material and record the locale settings that affect dates and numbers.
Installation steps
- 01
Install the matching package
Verify LibreOffice 26.2.5, the operating system and the processor architecture, then set the interface language and default save format on first launch.
- 02
Check fonts and locale
Open a test file and review substituted fonts, page breaks, dates, decimal separators and formulas before editing the real document.
- 03
Establish a two-format workflow
Keep the editable source in ODT, ODS or ODP when appropriate, and create DOCX, XLSX or PPTX copies for external collaboration instead of overwriting the only source.
Quick start
- 01
Create an ODF source
Make a small change in Writer, Calc or Impress, save in the matching ODF format, close and reopen it to confirm that the editing structure is preserved.
- 02
Verify an Office copy
Save a copy in the requested Office format and check page breaks, fonts, charts, formulas, animations and comments in the target application.
- 03
Export a fixed-layout PDF
Check page size, headers, links and fonts before exporting, then review the generated PDF page by page rather than replacing the export with screenshots.
Usage tips
- ODF preserves editing, Office formats support collaboration and PDF preserves delivery layout; each serves a different purpose.
- Keep macros disabled for unfamiliar documents and work on a copy when testing compatibility.
- Recheck spreadsheets after changing locale, fonts or formula settings.
Troubleshooting and uninstall
Why does a DOCX or XLSX layout change?
Check missing fonts, page styles, macros, charts, formulas and locale settings. Compare the original and the exported copy in the recipient's application.
Why should a macro not be enabled immediately?
A macro can execute automation code. Confirm its source and purpose first, and test on a copy without sensitive data.
- Back up working filesSave ODF sources, exported copies, templates and custom dictionaries before removing the application.
- Remove the applicationUninstall through the operating system. Decide separately whether to keep user templates, profiles and recovery files.
Frequently asked questions
Is LibreOffice suitable for everyday office work?
Yes. It provides word processing, spreadsheets, presentations, drawing, database and formula tools under free and open-source licenses; verify the terms for a specific redistribution.
Will Office files always look identical?
No. Complex fonts, layout, charts, macros and proprietary features can differ. Keep the original and validate important deliveries in the recipient's application.
Is it safe to enable a macro in a received document?
Treat macros as executable automation. Check the sender and purpose, keep them disabled for unfamiliar files and test a copy before enabling them.
