How to find the large files in your photo library.

My Apple photo library was way bigger than it should be. It turned out I had some very large videos in it. There’s no way of arranging your photos by size from within the Apple photos app. There is a way to browse these files outside of Apple Photos and arrange them by size. Here’s how to see the largest files in your Photo Library.

Here’s a video explaining it, otherwise read on!

View the Photos Library

To find your photo library in your Finder, go to your user folder (the one that looks like a house icon) then go to the ‘Pictures’ folder then find a file called ‘Photos Library.’

Photos Library is actually a folder, but if you click it, it will just open the Photos app. So, to see what’s inside the folder, you need to right-click and select ‘Show Package Contents.’

Right click to open your Photos Library in the finder.

Now click on the folder that says ‘originals.’ Inside this there will be multiple folders storing your photos (mine were numbered 0-F).


Open one of these folders and you will see all your photos.

To sort by size you need to turn on ‘View Size.’

Turn on ‘View Size’

With the Photos folder open in the Finder, go to the menu bar at the top of the screen and select ‘View’ and then ‘Show View Options.’

Now tick the option that says ‘Size.’ This will display the file sizes.

Now all the sizes of the photos (and movies) will be displayed.

If you click on the ‘Size’ column at the top of the window this will sort from largest to smallest.

Here all the photos are sorted by size.

You can now see the movies that are taking up a lot of space.

You can play the movies (hit spacebar) then decide whether to delete them or move them out of your Photos Library.

    Your YouTube video says that large files can be deleted from the Originals folder (or its sub-folders). This is completely wrong. Deleting or even modifying files in the Photos Library package file may corrupt the library beyond repair. The photos.sqlite database stored in the Database folder maintains detailed information on every file in the Originals folder. Contents of the other folders, e.g. Resources also relate to contents of the Originals folder. Even repairing library may not solve the problems that direct deletions from Originals may cause. So, while it’s OK to check which are your largest files as you have suggested, deletions should only be performed via the Photos app.

    Another thing to note: If you use iCloud Photos with Optimize Mac Storage setting, your largest files will be in iCloud – and deleting items from the Originals folder won’t delete them from iCloud.

    1. I’ve not found any problems deleting from finder, but thanks for the warning!

    The macOS app PhotoSort (https://apps.apple.com/app/id6739038077) does this. It sorts the Mac Photos library by file size and technical quality. If photos on Mac are “optimized” i.e. full resolution versions are in iCloud, it sorts using the size in iCloud. The sorting created on Mac can also be seen on iCloud-synced iOS devices. The free version only shows the 30 largest files; the full version sorts everything.
