Google just made the EPUB format available in Google Docs. That means you can save your Google Docs in a format that will display nicely on a variety of devices.
As an example, once you save a file in EPUB format you can read it with iBooks on a Mac or iPad. Here are the steps.
- Click File>Download as>EPUB Publication.
- Double-click to open the file that was downloaded.
- iBooks will open the file if the program is installed.
