For the best security and functionality, keep your web browser up to date. All modern browsers should update automatically, but please make sure your browser has auto-updates enabled. Microsoft Edge and Internet Explorer will get their updates through Windows Update; it's important that you install those updates as they become available.
For more information see: Frequently Asked Questions about Windows Update.
Desktop and laptop computers
Use the most recent versions of the following browsers for the best experience with Office Online.
Windows 10: Microsoft Edge, Internet Explorer 11, Mozilla Firefox, or Google Chrome
Windows 8, 8.1, or 7 (SP1): Internet Explorer 11, Firefox or Chrome
Windows Vista (SP2): Firefox or Chrome, but some features may not be available. We recommend updating to at least Windows 7 (SP1).
Mac OS X (10.8 and later): Apple Safari or Chrome
Linux: Office Online works in both Firefox or Chrome on Linux, but some features may not be available.
If your organization is dependent upon Internet Explorer 8 or Internet Explorer 9 to access older web apps and services, you may want to consider upgrading to Internet Explorer 11 and evaluating Enterprise Mode for Internet Explorer 11. This update helps provide better backward compatibility for legacy web apps.
iPad: If you're using at least iOS 10.0 we recommend using the Office for iPad apps instead. You'll find them in the Apple app store.
If you're using an older version of iOS then Safari is the best browser for Office Online on iPads, but some features may not be available.
iPhone: If you're using at least iOS 10.0 we recommend using the Office for iPhone apps instead of the browser. You'll find them in the Apple app store.
If you're using an older version of iOS then Safari is the best browser for Office Online on iPhones but some features may not be available.
Note: Not sure which version of iOS you have? See Find the software version on your iPhone, iPad or iPod (Apple Support)
There are currently no browsers on Android that are officially supported with Office Online. We recommend using the Office for Android apps instead. You'll find them in the Google Play store.
Most Office Online features will work in the Microsoft Edge browser on Hololens or XBox One.
