The best free office suites

When it comes to office productivity suites, there is little doubt that Microsoft Office dominates. But despite its deep roots and reknown, as well as its comprehensive array of offerings, Office is not necessarily the best option for everyone. Parsing the ever-expanding list of features—many of which you’ll never use—can feel overwhelming. For the majority of users, Word, Excel, and PowerPoint are all that’s really wanted. Which brings us to the final issue: Office’s hefty price tag.

Fortunately, free office suites abound, many of which are compatible with Microsoft Office docs. We compared six of the most popular free alternatives to see how well they replicate the most commonly used features of Microsoft Office.

Updated on 8/16/21 to include our review of OnlyOffice Desktop Editors, which has the nifty distinction of encompassing document, spreadsheet, and presentation editing software within a single app, so you can work among all types side-by-side.

Best overall Microsoft Office alternative

Kingsoft’s WPS Office delivers the most Office-like experience of all the suites we tried. Built around its own versions of Word, Excel, and PowerPoint, it offers excellent compatibility with all Microsoft Office formats and features a customizable interface that can be tailored to your preference for either the ribbon toolbar or the static menus of Office 2003. It’s also the only desktop suite in our roundup that included integrated cloud storage for easily sharing and collaborating on files. (Read our full review.)

Runner-up

Google Docs, Sheets, and Slides simply can’t be beat for collaboration. Its document review features and integration with Google Drive make it our go-to solution for anyone who routinely needs to co-author documents with others in real time. It also has tight ties with other Google products, including, of course, search, giving it capabilities you won’t find in any other office suite. Its relatively spartan interface is a welcome respite from Office’s busy toolbars, too. (Read our full review.)

What to look for in a free office suite

When evaluating Office alternatives, don’t look to replicate every feature, just the ones you need and use most. Depending on your situation, that could be robust spreadsheet calculations and dynamic presentation design or the ability to access files from anywhere and share them with remote team members. At minimum, keep these considerations in mind:

• The big three: Though Microsoft Office has expanded over the years to include programs like Outlook, Access, and Publisher, its bread and butter is still its original trio of programs: Word, Excel, and PowerPoint. That’s because nearly everyone uses these three apps regardless of the nature of their work. For many of us, they are the only three we need in a suite.
• Office compatibility: Most of the working world will continue to use Microsoft Office long after you’ve jumped ship. That means you’ll still have to work with official Office files. Look for a suite that can cleanly read and write Microsoft Office formats, from the current DOCX, XLSX, and PPTX file types to legacy formats.
• Interface: The way you access an office suite’s features matters as much as the features themselves. Polarized opinions about Office’s ribbon toolbar underscore this. Make sure you’re comfortable with the way a suite lays out its tools and that you don’t have to dig too deeply for those you’ll use a lot.
• Collaboration capability: The irony that we still rely on “office” suites when many of us no longer work in physical offices means the ability to collaborate remotely with others is now a required feature. If you don’t want to have to email documents back and forth for editing—which can play havoc with version control —you’ll need an alternative that includes cloud support for easily sharing files and ideally the ability to co-author (i.e. make edits and comments on a document) in real time.
