How To Reduce Size Of Iphoto Library



I ran into a problem where one of my 256GB MacBook pro ran out disk space. It turned out the problem was caused by a run away Mac OS/X photo library. I had two photo libraries on the Mac totaling about 200GB (sizes shown in Finder, may not be actual sizes)!

First problem I found was the conversion of iPhoto library to Photos library left behind a 73GB file in /Macintosh HD/user/me/Pictures/. The solution was simple – delete the old photo library. I did not recover a full 73GB after I deleted the file, I got back 10-20GB according to Mac system storage page.

Before enabling this feature, I could reduce the size by importing with iPhoto and then telling iPhoto to delete after the import. I would also use the Image Capture app to mass delete older photos I had already imported. How to reduce iPhoto Library size to the absolute minimum. If you are using Dropbox then you might want to take a look at your /Dropbox/Camera Uploads/ folder, since it might contain many images that may or may not be in your iPhoto folder. A window opens asking “Which iPhoto library do you want iPhoto to use” You can choose a library from the box or click Other Library and locate a library in another location. Once you have located the correct library, click Choose. IPhoto will launch the library you selected. If you’d like to switch to a different library, you must.

PowerPhotos includes a license for iPhoto Library Manager, which has similar features. Both apps can identify duplicates within a library to reduce a library’s size if you have many images that.

The second problem was new photo library /Macintosh HD/user/me/Pictures/Photos Library.photolibrary had a size of over 120GB. It was way too big for the 30k+ photos I had on the Mac. I did a bunch of clean up hoping that they would shrink the photo library. But to my dismay, the photo library only reduced by about 10%. The steps I took to do the cleanups are:

  1. Export photos that I did not need on the Mac to an external drive. It took only seconds to export thousands of photos. The steps are:
    • Connect a USB hard disk to a Mac
    • Open Photos
    • Select File | Export | Export Unmodified Original for 10 Photos…
    • Select a location in the USB hard disk
  2. Delete photos that I had exported
  3. Delete photos in Recently Deleted folder in Photos
  4. Run repair on photo library to make sure photo library is problem free. This takes a couple of minutes on a fast MacBook. The steps are:
    • Hold down <Command> + <Option> when opening Photos
    • Select Repair

I spent hours searching the Internet and Apple forum hoping someone had encountered the same problem before me and found a solution. No luck! I also posted a question on Apple forum but did not get any response. May be I was the only one that had come across this problem.

I noticed on other Macs that photo libraries grew and shrink when I added or deleted photos, but not the photo library on this MacBook Pro. Older version of Apple photo apps iPhoto or Aperture had functions to compact a photo library, however I cannot find the same feature in the new Photos app.

I was pissed! I decided to find a solution myself. Here is what I did:

  1. Export all photos in photo library to a USB hard disk (same as above)
  2. Delete photo library /Macintosh HD/user/me/Pictures/Photos Library.photolibrary on my Mac (I did this in Finder)
  3. Create a new photo library. The steps are:
    • Hold down <Option> when opening Photos
    • Select Create New…
  4. Import photos I just exported. The steps are:
    • Open Photos
    • Select File | Import…

After all the agony, my photo library is less than 17GB.

Hope this helps!
