Open the PDF in your Google Drive, select "Open with" and "Google Docs" from the drop-down menu.
That's it! Google will do its magic. This magic is new, your new documents may require some formatting. The more formatting there was on the original PDF, the harder it will be to convert.
Who can benefit:
Students who need text read aloud. After converting to a Google Doc, use Google Read&Write.
Anyone who wants to annotate their work - highlight, make comments, create a vocab list.
Everyone. We've all had a PDF we wished we could edit at some point.
