Transfer photos to Google Drive

You have a couple options, use the Google Photos app to auto backup photos or manually move photos from their Photos app to Google drive through the Files app.

Save Photos to Google Drive through the Files App:

1. In the Apple Photos app, select the photos you wish to upload,
2. Then tap on the share icon, select the "Export Unmodified Originals" or the "Save to Files" option,
3. Navigate to the Google Drive section and open a folder you wish to save them in and then tap on Save.

Depends. Google Photos has automatic upload and shares space with google drive. It's confusing, but this is a separate app.

Photos will prompt you after you log in to see if you'd like to upload your photos as a backup.

The only negative to google photos is that it compresses the photos a bit by changing the color grading. It's not that visible but if you care about that kind of thing, iCloud might be better.

You can manually store iPhone photos in Google Drive by using the app's upload feature, though Google Photos is generally better for automatic backups
