Office for the web Service Description
Office for the web (formerly Office Web Apps) opens Word, Excel, OneNote, and PowerPoint documents in your web browser. Office for the web makes it easier to work and share Office files from anywhere with an internet connection, from almost any device. Microsoft Office 365 customers with Word, Excel, OneNote, or PowerPoint can view, create, and edit files on the go.

Feature availability across Office for the web plans
Need help figuring out which Office solution best fits your organization? The following tables compare Office for the web feature capabilities to feature-rich Microsoft Office desktop apps. Use the tables to discover what features are available in Office for the web, and then select the feature name to read a brief description about how that feature works. You might discover that some people in your organization need the advanced charting capability of the Excel desktop app while others only need to view and lightly edit Word documents and PowerPoint presentations with Office for the web.
Note
A limited selection of Office features has been chosen to represent the advanced capabilities of the Office desktop suite. The tables are not a comprehensive list of Microsoft Office features.
Microsoft Office 365 ProPlus is a monthly subscription offer of the latest Office desktop suite.
Microsoft Office Online Server on-premises customers get an Office for the web editing license if they have purchased an Office desktop suite license (such as an Office Professional Plus, Office Standard, or Office 365 ProPlus license).
Note
When you open an Office document, either as an Outlook email attachment or from a SharePoint document library, the document will launch in Office for the web and will be read-only. To edit a document in Office for the web (edit mode), you need an Office 365 suite license, such as Office 365 Enterprise E1. To edit a document in the desktop app, you need an Office desktop suite license, such as an Office 365 ProPlus subscription or an installed version of Office Professional Plus 2010.
