How do I find the biggest videos in my Photos library?

Short answer: Open Media Types → Videos in Photos, or make a Smart Album filtering for movies; long and 4K videos are usually largest. Empty Recently Deleted afterwards.

Photos doesn't sort by file size, but you can narrow things down quickly:

  • Open Media Types → Videos in the sidebar to see only videos; long and 4K videos are usually the biggest.
  • Make a Smart Album (File → New Smart Album) with conditions like Photo is movie and a date range to review old videos.

Delete what you don't need, then empty Recently Deleted. Before deleting, consider exporting originals of anything precious to an external drive.
