Go through photos and delete smaller ones

finder

I have a folder of several hundred JPGs. All of them are either big (640×480) or small (350×250). I'd like to delete all the small images in one batch.

In the past, I've opened all the pictures in Preview, then flipped through them and pressed the delete key for the small ones. However, when I just tried that, Preview is showing the images as "locked" and is ignoring my tap on the delete key. (I don't know why this used to work and now doesn't…)

So I'm looking for another solution. Some thoughts about possible solutions:

  • Is there a way to add a column to the Finder list view that shows the image dimensions? Then I could sort by that column and delete the small ones in one swoop. (This would be really nice since it would be nice to see the dimensions for all the images in the folder, regardless.)

  • Can I get Preview to let me use the delete key, like it used to?

  • Maybe there is a solution using Automator?

I definitely do NOT want any solutions that involve installing new software just to perform this (seemingly simple!) task.

Best Answer

  1. Open finder and navigate to that folder
  2. cmd + F
  3. Search "in this folder"
  4. Add in the search option "other"
  5. When the option menu pop up, select "Pixel Height"
  6. Add another "other", "Pixel Width"

Then search, and delete.
