We are glad to announce Google Drive support for CloudConvert!
It is both possible to select files from Google Drive as input files and to send your converted files into your personal Google Drice account. When you do this the first time, you will be asked for the necesarry permissions. You can manually connect with Google Drive here. Don't worry, we access the Google Drive API in "Per-file access mode", which means we can technically only access the files you explicit send to us.
Also, it is possible to use CloudConvert directly within Google Drive (after you connected your account with Google Drive). Just right click on any file, select "Open With" and send it to CloudConvert.
