Upload a document to Pages for iCloud
You can upload a document created in Pages for Mac or in Microsoft Word to iCloud Drive so you can edit it on the web using Pages for iCloud. You can also upload files saved in plain text (with a .txt filename extension), Rich Text Format (with a .rtf filename extension), or Rich Text Format Directory (with a .rtfd filename extension).
Do one of the following:
With the document manager in browse view, drag a document from your computer to the document manager.
In the document manager, click the Upload button
in the toolbar, select a document, then click Choose or Open.
