Google Photos is a photo-sharing and storage service developed by Google. Currently, Google Photos allows users to store unlimited images (and HD video) as long as they’re under 16 megapixels.
Starting on June 1, 2021, new photos and videos will all count toward the 15 gigabytes of free storage that the company offers to anyone with a free Google account.
This means that photos and videos backed up before June 1, 2021, will still be considered free and exempt from the storage limit. You can verify your backup quality at any time in the Photos app by going to back up & sync in Settings.
Plans start at $1.99/month for 100GB, $2.99 (200GB), $9.99 (2TB) and beyond. The three entry tiers have annual payment options: $19.99, $29.99, and $99.99, respectively.
