Configure LibreOffice as the default suite in Windows

If you've decided to stop paying for Microsoft Office and switch to LibreOffice as your main office suite , it's normal that you want everything to work just as easily as before: double-click on a .docx, .xlsx or .pptx file and have it automatically open in LibreOffice, without having to choose a program each time.

Furthermore, many users prefer LibreOffice to closely resemble Microsoft Office in appearance, formatting, and behavior , making the transition less jarring at home, in the office, or at school. Let's explore, step by step and with many additional options, how to fully integrate LibreOffice into Windows as the default suite and fine-tune its functionality.

Why choose LibreOffice as an alternative to Microsoft Office

LibreOffice is a free, open-source, and very complete office suite that has been evolving rapidly for years. It originated as a fork of OpenOffice, but over time it has surpassed it in almost every aspect: more features, better compatibility, and a much more active development cycle.

One of the project's cornerstones is maintaining high compatibility with Microsoft Office formats . This means you can open and edit .docx, .xlsx, .pptx, and even older Word , Excel, or PowerPoint documents without much trouble—a key benefit if you're coming from Office or work with people who still use it. If you need to ensure a .docx file remains unchanged when opened in LibreOffice, see how to create a .docx file in Word that won't be altered.

The suite includes everything most users need on a daily basis: Writer (word processor), Calc (spreadsheets), Impress (presentations) , plus tools for mathematical formulas, databases , drawing, and more. And all of this is free for individuals, businesses, and public administrations alike.

The pace of improvement is constant thanks to frequent updates that fix bugs, expand features, and refine compatibility with Office. This makes it increasingly easy to migrate from Microsoft Office without missing much of anything.

Precisely because of this continuous improvement, it makes sense to dedicate a few minutes to thoroughly configuring LibreOffice after installing it , so that you take full advantage of its features and don't get frustrated with silly details like file associations or default formats.

Configure LibreOffice as the default application in Windows

To make LibreOffice behave as your default suite on Windows , there are two fronts you must cover: what you can configure from LibreOffice and what you have to change from the Windows settings themselves.

Choose LibreOffice as the default during installation

If you haven't installed the suite yet, you can perform a custom installation during the LibreOffice installation wizard . One of the steps includes a "File type" section where you'll see several selectors for Word, Excel, PowerPoint, and Visio documents.

By selecting these options, you tell the system that all those file types should open with LibreOffice from now on . It's the quickest way to configure basic file associations from the start and then forget about it.

If you already have it installed and didn't select those options, don't worry: you can adjust the associations later , both from LibreOffice and from Windows settings, as we'll see now.

Using file associations from LibreOffice (Windows) options

LibreOffice also provides a direct way to access the default Windows program settings. In the top menu bar, go to Tools > Options > LibreOffice > General . At the bottom, you'll find the "LibreOffice File Associations" section.

There you'll see the "Windows Default Apps" button (Windows only). Clicking it opens the "Default Apps" page in the system settings, where you can specify Writer, Calc, or Impress as the applications assigned to the file types you want.

In that same section, the "Check default file associations at startup" option makes LibreOffice check, every time it starts, whether it has lost any previously established associations. If it detects that a file format no longer opens with LibreOffice, it will display a notification so you can recover it with a single click.

Configure default programs in Windows 10 and 11

In modern versions of Windows, you can set default apps from several places. The most direct is the Start menu: go to Settings > Apps > Default apps.

On that screen, you can choose, for example, which program you want for email, photo viewer, music player , and, most importantly, the application to open documents. If you tap on the current application associated with documents or specific types, you can select LibreOffice Writer, Calc, or Impress as the default.

If you want more details, scroll down the same page to the "Choose default applications by file type" link . You'll see a huge list of extensions ( .doc, .docx, .xls, .xlsx, .ppt, .pptx , etc.). Simply click on the application associated with each extension and select the corresponding LibreOffice component.

Change the default program from the context menu

Another very useful way, especially if you only want to change a specific file type, is to do it from the File Explorer itself . Imagine you want .docx files to always open with LibreOffice Writer.

Right-click on any .docx file and select "Open with" > "Choose another app" . In the dialog box that appears, select LibreOffice Writer from the list (if it doesn't appear, click "More apps"). Then check the box that says "Always use this app to open .docx files" and confirm.

From that moment on, simply double-clicking any file with that extension will open it directly in LibreOffice . You can repeat this same process with .doc, .odt, .xls, .xlsx, .ppt, .pptx, PDFs, etc.

Assigning multiple formats to LibreOffice from the Control Panel (classic method)

If you prefer the traditional method, you can also configure default programs from the classic Windows Control Panel . Go to Control Panel > Programs > Default Programs.

Inside, there's a link called "Make a file type always open with a specific program ." Clicking it will show you a list of file extensions and their associated programs. Select the desired extension (for example, .docx or .ods) and click "Change program" to set the appropriate LibreOffice component.

This method requires going format by format, but it gives you very fine control to assign a whole battery of extensions to LibreOffice in a few minutes without having to touch anything else.

Adjust LibreOffice to work with Microsoft Office formats

If you frequently share documents with people who use Microsoft Office, you'll want LibreOffice to save in .docx, .xlsx, and .pptx formats by default , avoiding manual conversions every time you click Save As.

Save by default in .docx, .xlsx and .pptx

To change the default save format, open LibreOffice and go to Tools > Options > Load/Save > General . At the bottom of the window, you will see the section "Default file format and ODF settings".

In the "Document Type" list , you can choose Writer, Calc, Impress, etc. Right next to it is the "Always Save As" dropdown menu. For Writer, select "Office Open XML Text (.docx)"; for Calc, [the appropriate option]; and for Impress, "Office Open XML Presentation (.pptx)".

This way, every time you create a new document in Writer, Calc, or Impress and click Save, the default format will be the one compatible with modern versions of Microsoft Office . You can still save in ODF format whenever you want using Save As if needed.

ODF versions and compatibility with other free suites

Even if you prefer Microsoft formats for sharing, it's important to understand how LibreOffice handles its native ODF format . In the same options section, you'll find the "ODF Format Version" option; learn more about ODF formats.

LibreOffice saves by default in ODF 1.3 Extended , which offers more advanced features, but can cause problems if you open those documents with older editors such as Apache OpenOffice or older versions of LibreOffice.

If you work in mixed environments with other free suites, it may be a good idea to switch to ODF 1.2 Extended (compatibility mode) to minimize surprises with features that don't understand each other.

Managing VBA macros when working with Office documents

When you open Word or Excel documents with VBA macros, LibreOffice lets you decide what to do with those macros . Go to Tools > Options > Load/Save > VBA Properties.

There you can choose to keep the original Basic code so that it continues to work if the document is reopened in Microsoft Office, load the code into LibreOffice to try to edit it, or convert it into an executable within the suite.

If you want to eliminate any risk of macro viruses, uncheck the option to save the original code, so that the document is saved without those embedded macros when you export it again.

Customize the appearance of LibreOffice to resemble Microsoft Office

One of the most common comments from those coming from Office is that LibreOffice's "classic" interface looks a bit simple or outdated . The good news is that the suite has many customization options to make it more modern, even giving it a look very similar to the Office ribbon.

Change the style and size of the icons

To start, you can give your icons a quick makeover. Go to Tools > Options > LibreOffice > View . Under "Icon Style" you'll find several themes: Breeze, Breeze Dark, Colibre, Elementary, Karasa Jaga, Sifr, etc.

Select the theme that best suits your taste; many users find Colibre or Breeze more modern and appealing. Just below, you can adjust the "Icon Size" in the toolbar, sidebar, and Omnibar (Automatic, Small, Large, Extra Large).

With this combination you can achieve a cleaner interface, with clear and easily visible icons , something especially useful on large screens or if you work many hours at a time.

Activate the Office ribbon-style tabbed interface (Muffin).

LibreOffice incorporates an interface called "Muffin" that includes several alternative styles to the classic toolbars. The one most similar to the Microsoft Office ribbon is the "Tabbed" interface , which groups commands into tabs such as Home, Insert, Design, etc.

In recent versions, simply go to the View menu > User Interface and choose "Tabbed." If you're using an older version (prior to 6.2), you'll first need to go to Tools > Options > LibreOffice > Advanced and check "Enable experimental features." Accept the warning, restart if necessary, and then you'll be able to change the interface type.

Once the tabbed interface is activated, LibreOffice takes on a look much more similar to Microsoft Office , which is a big help to users accustomed to the ribbon and who get lost with traditional toolbars.

Apply themes and colors to the interface

If you want to go a step further, go to Tools > Options > LibreOffice > Customization . There you can choose a "Pre-installed Theme" that changes the overall appearance of the interface.

Simply select one of the available themes, click "Apply," and after a few seconds, you'll see the backgrounds, toolbars, and some visual elements change. It's not as extreme as in some other programs, but it helps you customize the environment to your liking.

Application colors and visible elements

In LibreOffice > Application Colors, you can adjust which elements are displayed (text boundaries, table borders, page breaks, etc.) and what colors they use. This includes things like field shading colors, comments, guides, and margins.

You can select or deselect each element to make it visible or hidden, and choose a different color in the "Color Settings" column. Additionally, you can save your color scheme to reuse it whenever you want.

Configure identity data, routes, and backups

If you are going to use LibreOffice in professional or educational environments, it is advisable to take care of author data, working paths and backups to keep everything organized and secure.

Enter your identity details

In the options menu, go to LibreOffice > Identity Data . Here you can fill in your name, initials, organization, and other similar information.

This information is used, among other things, for document properties ("created by", "modified by"), to identify the author of comments and recorded changes, and as the sender in certain mail functions.

If you do not want your personal data to be stored in the document properties, you can uncheck the "Use data for document properties" option , although you will lose some author traceability.

Choose document paths, backups, and templates

LibreOffice lets you define exactly where it saves documents, templates, backups, images, etc. by default. This is done in LibreOffice > Paths.

Select the item type (for example, "Backups," "Templates," or "Gallery") and click "Edit" to change the associated folder. You can add or remove paths depending on whether you want to store everything on a single drive, in a network folder, or in a cloud-synced directory.

It's a very convenient way to keep office materials well organized , know where backups are stored, and facilitate copying or migrating to another computer.

Enable automatic backups and recovery

In Load/Save > General, you have several key options to avoid surprises. For one, "Save automatic recovery information every X minutes" allows LibreOffice to save recovery data for all open documents. You can also learn how to use file versioning to maintain historical versions.

On the other hand, the "Always create a backup" option ensures that every time you save a document, the previous version is also saved as a .BAK file in the backup folder defined in "Paths".

If your documents are long or important, these settings make all the difference when an unexpected shutdown or system failure occurs , helping you recover lost work.

Optimize display, performance, and accessibility

Beyond associations and appearance, you can adjust various options related to visual aids, graphics acceleration, and accessibility to make working with documents more comfortable and tailored to your team.

General help options and dialogs

In LibreOffice > General , the "Help" sections allow you to activate things like extended tooltips (more detailed tooltips about icons and commands) or the warning if local help is not installed.

In the "Open/Save Dialog Boxes" section, you can choose whether to use LibreOffice's own dialog boxes or your operating system's standard dialog boxes . If you're used to Windows dialog boxes, you might prefer to leave the "Use LibreOffice dialog boxes" option unchecked.

Graphics performance and Skia usage

Within LibreOffice > View, you'll also find the "Graphics Output" options. There you can enable "Use hardware acceleration" to make better use of your graphics card , as well as "Use anti-jamming" to smooth graphic edges.

Options such as "Render the entire program with Skia" or "Force Skia software rendering" control the use of this 3D graphics library. Not all systems support it perfectly, and in some cases you may need to disable it if you experience glitches or rendering problems.

Accessibility and high contrast

In LibreOffice > Accessibility, you can disable animations, enable high-contrast modes, and change the font used in the interface. This is especially useful if you have vision problems or if you use a high-contrast theme on your system.

It also relies, on certain platforms, on the Java Runtime Environment to communicate with assistive technologies , so it is advisable to have a suitable JRE or JDK installed if you use screen readers or other similar tools.

Security, updates, and advanced settings

Finally, it's worth taking a look at the options related to document security, macros, certificates and automatic updates, as well as the advanced settings for more technical users.

Security options and alerts

In LibreOffice > Security, you can define warnings and behaviors when saving documents. The "Options" button opens a dialog where, for example, you can force the removal of personal information when saving or enable the "Ctrl + click to open hyperlinks" behavior.

This last option makes you hold down the Ctrl key when clicking on a link, which prevents you from accidentally activating them while editing.

Macro security, certificates, and timestamps

The "Macro Security" button opens a dialog box where you can choose the security level for running macros and define trusted document sources. It's important to maintain a reasonable level of security to avoid accidentally running malicious macros .

On non-Windows systems, you can also choose the "Certificate Path" to tell LibreOffice where to look for certificates used in digital signatures . Additionally, there's a "Time Stamp Authorities" (TSAs) section to add URLs that provide reliable timestamps to signed PDF documents.

Online update

In LibreOffice > Online Updates, you decide whether and how often you want the program to automatically check for updates. If you select "Check for updates automatically," you'll see an icon in the menu bar when a new version is available.

You can also enable "Download updates automatically" so that they are downloaded in the background and installed when you decide, as well as allow basic system information to be sent to the server for statistical purposes.

Java and advanced features

In LibreOffice > Advanced , you configure Java usage. Some features, such as certain wizards, the MediaWiki Publisher , or parts of Base, require a JRE or JDK to be installed.

From this page you can select which Java environment to use if you have several, as well as activate options such as "Enable experimental features (may cause instability)" or "Enable macro recording (limited)".

The "Open expert settings" button grants access to an advanced dialog where you can fine-tune internal parameters. This is a delicate area: changing options without knowing what you're doing can destabilize your user profile , so it's best not to touch anything if you're unsure.

With all these settings—file associations in Windows, saving formats, Office-like appearance, paths, security, and performance—it's possible to have LibreOffice functioning as a fully integrated default office suite in Windows , convenient for everyday use and ready for both home users and professional environments looking to get the most out of a free and open-source tool.
