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 devices with a supported browser and an internet connection. Microsoft 365 customers with Word, Excel, OneNote, or PowerPoint can view, create, and edit files on the go.

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 a 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 a Microsoft 365 Apps for enterprise subscription or an installed version of Office LTSC 2021.
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 Microsoft 365 Apps for enterprise license). Microsoft 365 Apps for enterprise is a monthly subscription offer of the latest Office desktop suite.
