Photos library on Mac: what it is and whether you can delete it
~/Pictures/*.photoslibrary
No: it's your data
Deleting it loses information. If you need the space, free it from the app that manages it.
What it is
Your photos and videos.
How to free the space
Photos → Settings → iCloud → Optimize Mac Storage.
DiskSpace AI finds it for you
It tells you how much it takes on your Mac, what it is and whether you can delete it. It only selects what recreates itself, and your files are kept 7 days in case you change your mind.
