I already have my PDFs in Google Drive, can I import them directly from there?

No. For privacy reasons Paperpile can only access files that were uploaded by Paperpile and are stored in the Paperpile folder. So Paperpile can't access your PDFs that you already have in some other location in your Google Drive.

We suggest to sync the files to your local hard drive and upload them again from there. See our guide how to upload file .
