For instance, if I go to Preview, Settings here and then go to Images you could see When Opening File, if I have it set to open each file in its own window, then opening all of these will open every single one in its own window and you can't use this technique. Now if that doesn't happen it may be because of your Settings. So they open in one window, not in Tabs, this one window here with all the images listed on the left. Then you'll see they open in Preview and what you're going to look for is a Sidebar that shows you all the images. I could just double click on one since they are all selected they should all open in the default app, which is Preview, or I could use Command O which is File, Open. I'm just going to use Command A since I want every file that is in this folder. You can use Shift Click to select them all on the List here. So the first thing you want to do is select them all. You can use Preview to Batch Process all of these. I've got 5 here but maybe you have 50 or 500 images. I could also go to File and then Export and then Export a new copy in a different format, perhaps reducing the file size considerably.īut what if I wanted to do it for a whole bunch of files. Then I could go to Tools and I can adjust the size, and change the size. If I were to double click on it it would open up in Preview by default. Now if I were to select one of these images and look at the information I could see it is 4032 pixels wide. However, you can also do it with a built-in Preview App on your Mac. Most Image apps, like PhotoShop, have this ability. So let's say you want to change the size or the format of a group of image files.
