LibreOffice is a free, full-featured productivity suite compatible with Microsoft Office formats and runs on Windows, macOS, and Linux. Built as the successor to OpenOffice, LibreOffice is trusted by millions worldwide. Its modern interface and robust tools help you create, collaborate, and get things done – whether you're writing a document, crunching numbers, or building a presentation.

LibreOffice includes everything you need in one package: Writer for documents, Calc for spreadsheets, Impress for presentations, Draw for diagrams and illustrations, Base for database management, and Math for formula editing.

What are the differences between LibreOffice and Microsoft Office?

LibreOffice has been designed to compete directly with MS Office so both include similar productivity tools with similar functions. The equivalent for Excel is Calc, then you have Word and Writer for word processing, PowerPoint and Impress for presentations. LibreOffice also includes Draw which is a vector graphics application and Base which is a database management system.

LibreOffice and Microsoft Office are both powerful office suites, but while LibreOffice is free, open-source, and prioritizes the OpenDocument Format (ODF), Microsoft Office is proprietary, subscription-based, and optimized for its own file formats.

Compatibility is good, and common office tasks translate well, though complex formatting or macros may render differently. LibreOffice offers strong support for older ODF files and version interoperability, but users occasionally encounter minor layout or compatibility issues when exchanging documents.

Can LibreOffice open Microsoft Office documents?

LibreOffice supports Microsoft formats like DOCX, XLSX and PPTX quite well, including many advanced features. Basic editing, formatting, spreadsheets, and presentations work well. However, highly intricate layouts, specific fonts, VBA macros, or track changes may not render identically. Saving in DOCX/XLSX is better supported now, and workflows work most of the time – just expect occasional minor reflows or formatting tweaks.

What's the difference between LibreOffice 7.x and LibreOffice 24.x?

The LibreOffice team transitioned versioning to reflect the calendar year (i.e., 24.x for 2024). Version 7.6 is now end-of-life, while the 24.2 branch is current, more thoroughly tested, and being actively updated with enhancements, bug fixes, and ongoing compatibility improvements. If you're transitioning from recent MS Office, 24.x will feel more complete and polished.

In addition to LibreOffice, are there other good (and free) MS Office alternatives?

Yes. OnlyOffice is frequently recommended for its excellent compatibility with Microsoft formats, while Google Workspace shines for real-time cloud collaboration. SoftMaker Office and WPS Office are also often recommended. Each has strengths: OnlyOffice excels in format fidelity, Google Workspace offers seamless online collaboration, and WPS or SoftMaker may suit different user preferences. LibreOffice itself is recognized as the most feature-rich open-source option

What does that little red arrow icon in Writer mean, and can it be removed?

The small red arrow indicates that there's additional content (like overflow text) in that area. It doesn't appear when exporting to PDF or printing, so hiding it isn't necessary for final output.

Features

Great-looking, well-structured documents

Your documents will look professional and clean, regardless of their purpose: a letter, a master thesis, a brochure, financial reports, marketing presentations, technical drawings and diagrams. LibreOffice makes your work look great while you focus on the content, thanks to its powerful styles system and structuring tools.

Use documents of all kinds

LibreOffice is compatible with a wide range of document formats such as Microsoft® Word (.doc, .docx), Excel (.xls, .xlsx), PowerPoint (.ppt, .pptx) and Publisher. But LibreOffice goes much further with its native support for a modern and open standard, the Open Document Format (ODF). With LibreOffice, you have maximum control over your data and content - and you can export your work in many different formats including PDF.

Get more features with extensions

Beyond the many features shipped by default, LibreOffice is easily extensible through its powerful extensions mechanisms. Get even more features and document templates on our dedicated websites.

Our software is tested and used daily by a large and devoted user community - we're open to new talent and new ideas, so get involved and influence its future.

Built on a strong heritage

LibreOffice is a successor to OpenOffice.org (commonly known as OpenOffice), which in turn was based on StarOffice. Many years of development have gone into the software, and it has been used in its various incarnations by millions. Today, LibreOffice is by far the most active continuation of the OpenOffice.org codebase, with releases every six months and hundreds of contributors. Also, LibreOffice uses libraries from the Document Liberation Project, handing control back to content creators.

What's New

The Document Foundation today announced the availability of LibreOffice 26.8, the new major release of the free and open source office suite, for Windows, macOS and Linux. Development began in December 2025, and the release consolidates the work of 206 contributors, of whom 155 are volunteers.

LibreOffice 26.8 concentrates on three areas: the typographic quality of what the suite produces, the range of writing systems it handles correctly, and the fidelity with which documents survive exchange with other office suites.

User interface

The Notebookbar now carries a distinct background colour for each application, so that Writer, Calc, Impress and Draw can be told apart at a glance. Its tabs have category labels and can be scrolled with the mouse wheel or touchpad. Changes to application theme colours no longer require a restart, and theme colours are reachable from the Notebookbar in Impress.

The list of styles is now consistent across the Notebookbar, the Formatting toolbar and the sidebar, and each entry is shown as a preview of the style itself. Style dialogues allow individual properties to be reset to those of the parent style. Paper sizes from A0 to B3 have been added to page settings. Custom dictionaries have gained a search filter, the Hyperlink dialogue can strip query strings from addresses, and resizable dialogues on Windows now have a maximize button. On macOS, the Emoji & Symbols, Dictation and AutoFill menu items are available.

Accessibility

Writer tables now report row and column index information as specified in ARIA, improving how screen readers convey table structure. The special character selector is fully navigable by keyboard.

Databases and automation

Base preserves SQL comments when a query is switched to Design View, and supports filtering on date, time and timestamp columns with the embedded Firebird database.

Python scripts can be created and edited directly from the Macro manager without installing an extension, and can instantiate UNO services through constructors rather than string identifiers. The ScriptForge libraries add a typed input dialogue, functional map, filter and reduce operations on Basic arrays, and a default named pipe that allows the same script to run unchanged inside LibreOffice or against it as a client.

Elsewhere in the suite

Keyboard shortcuts can be assigned to an individual document, so a shortcut can invoke a style that exists only in one template.

  • Writer opens very large documents containing images significantly faster.
  • A Draft view hides headers, footers and margins for distraction-free work.
  • The Quick Find sidebar searches through comments.
  • Table styles in Writer and Calc can be edited, and their internal representation has been converted from a binary format to XML.
  • Application theme colour changes no longer require a restart.
  • Additional paper sizes from A0 to B3 are available in page settings.
  • The style list is now consistent across the Notebookbar, the Formatting toolbar and the sidebar.
  • Automated testing now uses VeraPDF to validate PDF output.

No artificial intelligence

LibreOffice 26.8 contains no generative AI features. Documents are not transmitted to remote services for processing, and no component of the suite requires network access to function. This is a deliberate position. Any organisation handling confidential, legally privileged or personal data needs to know where that data goes, and the only assurance that survives an audit is that it does not leave the machine.

Writing systems

The largest single body of work in this release addresses bidirectional and complex text. Writer now detects paragraph direction automatically when documents or plain text are opened or pasted. Line wrapping places end-of-line spaces according to the direction of the paragraph rather than that of the adjacent characters. Object resize handles behave correctly in right-to-left and vertical CJK documents. Bidirectional control characters are now visible alongside other formatting marks. In Calc, typing right-to-left text into an empty cell sets the direction of that cell automatically.

Alignment semantics have been revised accordingly: new documents default to start alignment rather than left, and changing paragraph direction no longer mirrors explicitly left- or right-aligned paragraphs.

Math has gained named functions and operators for the N'Ko and Adlam scripts, used for the Manding languages of West Africa and for Fulani, together with left-pointing vectors and harpoons for right-to-left formulas. The CJK text grid option has been renamed to reflect what it actually does, namely enable the genkō yōshi manuscript grid. Font names recorded in languages other than the interface language are now resolved, so documents authored elsewhere display in the typefaces their authors chose.

None of this work has a commercial market. It was done anyway, because a foundation does not have to ask whether a language pays for itself before deciding to support it.

Typography

Writer introduces the Paragraph Composer, a text layout algorithm that balances word spacing across consecutive lines instead of optimising each line in isolation. The single-line, greedy approach used by word processors has been standard since the technology existed, and produces justified text that alternates between crowded and sparse lines wherever long words fall near a break.

OpenType font variations are now natively supported, allowing variable fonts to be used as designed, including axes that adjust letterform contrast and proportion to the size at which text is set.

Baseline grid alignment now works correctly for text inside frames, and the grid itself can be displayed while editing, with a configurable colour.

Document exchange

LibreOffice Chart provides basic round-trip support for the newer chart types that Microsoft Office writes into OOXML files: box-and-whisker, funnel, Pareto, sunburst, treemap and waterfall. These charts cannot yet be rendered or edited. LibreOffice displays a message identifying the unsupported type and preserves the underlying definition, so that a file opened and saved in LibreOffice returns to its originating application intact. Region map charts carry extensive geographic data that is not preserved; the chart type survives the round trip but little of its content does.

The distinction matters. A specification extended unilaterally by a single implementer is a moving target for every other implementer. Preserving what cannot yet be rendered is the discipline that keeps a document usable beyond the lifetime of the application that created it.

Calc improves the handling of line breaks in referenced cells in XLSX files, and form control elements in XLSX documents now appear in the Navigator.

Spreadsheets

Calc adds Calculated Fields to pivot tables. Data validity can now silently reject invalid entries, restoring behaviour available before version 24.2. Cell styles support relative font sizes. A Shuffle command randomises the order of cells in a range. The border toolbar button remembers and reapplies the most recently used style.

Presentations and drawings

Impress and Draw support multiple page sizes within a single document. Impress adds presentation sections for organising slides into named groups, displays custom slide names beside slide numbers in the panel, and can convert numbered lists to bulleted ones. Several embedded templates are now supplied in both 16:9 and 4:3 ratios, so that background artwork is no longer stretched when the ratio changes. In Draw, the functions of the mouse wheel can be swapped, making zoom the default action.
