How to get Microsoft Office for free

There are several ways to access Microsoft Office without spending your own money—either for a limited time, through your institution, or by earning funds online. Each method has pros and cons depending on how long you need Office and whether you require advanced features like macros or Power Query.

1-Month Trial

You can access Microsoft 365 for free with the 1-month trial (Microsoft 365 Family or Personal). You'll need a payment method to start, but you can cancel before the trial ends. This works well if you only need Office for a short project.

Set a calendar reminder to cancel a few days before the trial ends so you're not charged. The trial includes the full desktop apps, OneDrive storage, and Microsoft Defender. If you've used a trial before, try with a different Microsoft account or wait for promotional offers.

Office 365 Education

If you are a student or educator, you may be able to access Office 365 Education with your school or college email. Contact your IT department if you don't have access—Microsoft donates Office 365 to eligible institutions. This version is identical to the paid one, but note: your institution has full access to your data when using Office 365 Education.

Use Office.com

There is a free, official version of Office that you can use through your browser on Office.com. You get free access to Word, Excel, PowerPoint, and more with a Microsoft account. It lacks some features of the paid, downloadable version, but it's enough for casual use.

Earn Office with Earnne

Free alternatives to Microsoft Office

Several free alternatives offer similar functionality and work with Office file formats.

Google Docs, Sheets & Slides

Google's suite is just as capable as Microsoft's for many users. With a Google account, you get access to Docs, Sheets, and Slides in your browser, plus 15 GB of cloud storage. This is ideal if you work online. If you need offline access, this may not be enough.

LibreOffice

LibreOffice is a free alternative maintained by a non-profit. Download it for Windows, Mac, or Linux and enjoy similar functionality to Microsoft Office (Writer, Calc, Impress). It gets updates, though less frequently than Office.

MacOS Pages, Numbers & Keynote

If you have a Mac, you can use Apple's Office-like apps for free. Pages, Numbers, and Keynote come pre-installed or can be downloaded from the App Store. They open and save Office formats (Word, Excel, PowerPoint) so you can share files with others easily.

Summary: best options for free Microsoft Office

For most users, the free Office.com browser version or Google Docs is enough. Students and educators should check Office 365 Education first. If you need the full desktop version and don't qualify for discounts, earning with Earnne and buying from a third-party seller is a practical way to get Office cheap. Combine methods—e.g. use the trial for a project, then switch to LibreOffice—to stretch your options further.
