I just uploaded a few relatively large files (.dmg files, around 1-2 GB each) to my Google Drive and noticed the file sizes reported by Google Drive are significantly lower than the originals.

For one of the files:

  • macOS reports 806 MB.
  • Google Drive reports 769.0 MB.

Strangely enough, Google Drive also reports (806,819,752 bytes), which is roughly 806.8 MB.

What's going on here?

  • Is this some kind of bug?
  • Was an error encountered during the upload?
  • Does Google Drive automatically compress files for storage?
