iCloud: Pages for iCloud
Pages for iCloud is a web app that allows you to create and edit documents using a web browser on a Mac or Windows computer.
You can share a document with others by sending them a link to it. Recipients can click the link to view the document, and you can also allow them to edit it so you can all work collaboratively in real time. Any changes you or others make to the document are saved in iCloud, so everyone always sees the latest version.
Documents you create with Pages for iCloud are automatically available in Pages for iOS and Pages for Mac on all your devices set up to use iCloud. This integration works in both directions. For example, you can create a Pages document on an iOS device or a Mac, and it appears automatically on iCloud.com in Pages for iCloud. That means you can edit documents from anywhere—your devices, computers, or on iCloud.com—and the changes show up everywhere.
When working with Pages for iCloud, make sure you use a recommended web browser.
Note: To use Pages for iCloud, you need to use iCloud Drive. For more information, see the Apple Support article Use iWork with iCloud Drive.
