The best free Microsoft Office alternative in 2026 is LibreOffice. It is a full desktop office suite for Windows, Mac and Linux, it costs nothing for home or business use, and it opens and saves Word, Excel and PowerPoint files. If you mostly work with .docx, .xlsx and .pptx files and want something that looks closer to Microsoft Office, ONLYOFFICE Desktop Editors is the better pick (for quick PDF fixes, see how to edit a PDF for free), and if you live in a browser, Google Docs, Sheets and Slides are free with 15 GB of storage.
Below is our ranked list of five free options, what each one is good at, where it falls short, and how to switch without breaking your existing files. Every price, limit and feature was checked on the official websites on 7 November 2026.
Quick answer: the 5 best free Office alternatives
| Rank | Tool | Best for | Works on | Cost |
|---|---|---|---|---|
| 1 | LibreOffice | A complete offline suite with no account | Windows, macOS, Linux | Free (open source) |
| 2 | ONLYOFFICE Desktop Editors | Best Microsoft file compatibility, PDF editing | Windows, macOS, Linux | Free for personal and professional use |
| 3 | Google Docs, Sheets & Slides | Real-time collaboration in the browser | Any browser, Android, iOS | Free, 15 GB shared storage |
| 4 | Microsoft 365 free web apps | Real Word, Excel and PowerPoint, online only | Any browser, mobile | Free, 5 GB OneDrive |
| 5 | SoftMaker FreeOffice 2024 | A light, familiar desktop suite | Windows, macOS, Linux | Free for personal and business use |
How we ranked them: we looked at what you get for $0 without a trial, how well each tool handles Microsoft file formats, whether it works offline, which platforms it supports, and how many features sit behind a paywall. We used each vendor’s own pages for every fact. Where a vendor page didn’t confirm something, we left it out instead of guessing.
Why look for a free Office alternative at all?
On Microsoft’s US comparison page, Microsoft 365 Personal costs $9.99 a month or $99.99 a year, and Microsoft 365 Family costs $12.99 a month or $129.99 a year. That is fair value if you need the full desktop apps and 1 TB of OneDrive. But students, freelancers and small teams who just write documents, build simple spreadsheets and make the odd presentation often pay for features they never touch.
The good news is that every tool on this list reads and writes the Microsoft formats you already use, so you don’t have to convert your whole archive or ask clients to change anything.
1. LibreOffice: the best free Office suite overall
LibreOffice is the open-source suite run by The Document Foundation. It is the closest thing to “Microsoft Office, but free forever”: you download it, install it, and there is no account, no subscription and no paid tier waiting for you.
The suite has six apps: Writer (documents), Calc (spreadsheets), Impress (presentations), Draw (diagrams and simple layouts), Base (databases) and Math (formulas). The current release line is LibreOffice 26.8, released in August 2026. The Document Foundation describes that release as bringing better typography and support for more of the world’s writing systems, and it deliberately ships without built-in AI features.
The download page lists installers for Windows 10 or newer (x86_64 and Arm), macOS 10.15 or newer (Intel and Apple Silicon) and Linux (deb and rpm).
What it’s like to switch
LibreOffice saves in the OpenDocument format (.odt, .ods, .odp) by default, but it opens and saves .docx, .xlsx and .pptx files. If you share files with Office users, change the default once in Tools → Options → Load/Save → General and set “Always save as” to the Word, Excel and PowerPoint formats. The interface can also be switched to a ribbon-style “Tabbed” layout under View → User Interface if the classic menus feel dated.
Pros
- Completely free for home, school and business use, with no account
- Works fully offline
- Includes a database app and a drawing app that most free suites skip
- No AI features sending your documents anywhere
Cons
- Complex Word layouts and PowerPoint animations don’t always convert perfectly
- No built-in cloud storage or real-time co-editing
- Excel macros written in VBA may need rework
2. ONLYOFFICE Desktop Editors: best for Word, Excel and PowerPoint files
ONLYOFFICE Desktop Editors is an open-source desktop app for Windows, macOS and Linux. Its FAQ says plainly that it is free for personal and professional use.
The big difference from LibreOffice is the file format. ONLYOFFICE is built around Microsoft’s formats and advertises “native support for DOCX, XLSX, and PPTX”, so a file you save goes back to a Word or Excel user without a conversion step. It can also open ODT, ODS, ODP and CSV files. The interface uses tabs and a ribbon, so anyone coming from Microsoft Office will find things quickly.
It also edits PDFs, which is rare for a free suite: you can change PDF text “like Word documents”, fill in forms and create your own fillable forms. There is an optional AI layer called ONLYOFFICE AI Tools that you connect to an AI provider of your choice for things like text generation, translation and OCR. It is off unless you set it up.
Pros
- Saves straight to .docx, .xlsx and .pptx
- Familiar tabbed interface
- Free PDF editing and fillable forms
- Optional AI with your own provider
Cons
- No database or drawing app
- The cloud collaboration products (DocSpace and Docs) are separate, and their paid plans start at $149 per server per year for the Home edition
3. Google Docs, Sheets and Slides: best for working together online
If your team edits the same files at the same time, Google’s free apps are hard to beat. Google’s own page sums up Docs as a way to “write, edit, and collaborate wherever you are. For free.” All you need is a Google account.
Every Google account includes up to 15 GB of storage, but that space is shared across Gmail, Google Drive and Google Photos, and files you create in Docs, Sheets and Slides count toward it.
Microsoft files work in two ways. Double-click a Word, Excel or PowerPoint file in Google Drive and it opens in Docs, Sheets or Slides. In Chrome on a computer, Office Compatibility Mode lets you edit the file without converting it, then download it again as .docx, .xlsx or .pptx. Google’s help page lists what doesn’t carry over: macros aren’t supported, embedded charts and videos in Word and PowerPoint files become images, and SmartArt is converted to Google Drawings.
You can work offline too. Use Chrome or Microsoft Edge (not a private window), install the Google Docs Offline extension, and turn on offline access in Drive settings. Google’s offline guide walks through it.
Pros
- Best real-time collaboration and commenting of any free option
- Nothing to install, runs on any computer with a browser
- Automatic saving and version history
Cons
- 15 GB is shared with your email and photos
- Offline mode needs setting up in advance
- Macros and some advanced Office features don’t survive
4. Microsoft 365 free web apps: the real Office, in your browser
Many people don’t know that Microsoft gives away browser versions of its own apps. Sign in with a free Microsoft account at microsoft365.com and you can use Word, Excel and PowerPoint for the web at no cost. Microsoft’s support article on free web apps confirms that free users get 5 GB of cloud storage.
Because these are Microsoft’s own apps, formatting is as faithful as it gets. The limits are clear in the same article: there are no desktop apps, mobile editing is basic and only on screens under 10.1 inches, free users receive security updates but not new features, and AI usage is lower than on paid plans. Files need to be in OneDrive to share and co-edit in real time.
Pros
- Perfect compatibility with Word, Excel and PowerPoint files
- The interface you already know
- Free mobile apps for phones
Cons
- Online only, no desktop apps
- Only 5 GB of OneDrive storage
- Advanced features (some Excel tools, Access, Publisher) are paid-only
5. SoftMaker FreeOffice 2024: a light desktop suite
FreeOffice 2024 from German developer SoftMaker is a smaller, simpler desktop suite. SoftMaker’s site says it is “completely free, both for business and personal use”, on Windows, Mac and Linux.
It has three apps: TextMaker for documents, PlanMaker for spreadsheets and Presentations for slides. SoftMaker says they are compatible with their Word, Excel and PowerPoint counterparts. It is a good fit for an older laptop or for someone who wants a tidy, familiar layout without LibreOffice’s long menus. SoftMaker also offers TextMaker, PlanMaker and Presentations as free mobile apps for iOS and Android, but those are separate apps from the desktop suite.
Pros
- Free for commercial use
- Clean, familiar interface
- Runs on all three desktop systems
Cons
- Fewer features than LibreOffice or ONLYOFFICE
- Smaller community and fewer guides than LibreOffice
What about WPS Office?
WPS Office is often listed as a free Office alternative, and it does have a free version for Windows, Mac, Linux, Android and iOS that opens Microsoft and PDF files. We left it out of the top five because its own comparison page marks the AI tools as limited on the free tier and keeps more cloud storage and features for paid plans, and the page didn’t clearly spell out what the free version includes. If you try it, check the current plan details on the WPS site before you rely on it.
How to switch from Microsoft Office without losing anything
- Back up your files first. Copy your Documents folder (or OneDrive) to an external drive or another cloud folder.
- Pick one tool for a week. Choose LibreOffice or ONLYOFFICE if you work offline, Google Docs if you collaborate, or Microsoft’s free web apps if formatting must be exact.
- Test your three most important files. Open the documents and spreadsheets you rely on most, check headers, tables, charts and formulas, then save a copy.
- Set Microsoft formats as the default. In LibreOffice, go to Tools → Options → Load/Save → General and choose Word, Excel and PowerPoint formats. ONLYOFFICE already saves to them.
- Keep the free web apps as a backup. If a client sends a file with complex formatting, open it once in Word for the web to see how it is meant to look.
- Cancel your subscription last. Only stop paying once your everyday work runs smoothly in the new tool.
