I'm trying to save space on my Google Drive. I noticed I have several PDFs stored, most of which are over 1MB. According to Google Support, Google Drive can convert PDFs to Google docs (which is nice as it doesn't count against storage space). My question is what's the best way to do this given that several PDFs have already been uploaded to Google Drive? The manual way would be to download them all, upload and convert them, then delete the PDF versions. Is there a better way?
