As a Windows user, PowerToys is my go-to for resizing images now, since I can work with multiple images with just a few clicks. It's admittedly a bit easier to get this done on macOS, but it's not a difficult process either way. Then, in Preview, make sure you select the thumbnails for all the images you want to resize before using the Adjust Size option.Īnd that's about it. First, select all the images you want in Finder and open them with Preview. If you want to resize your images in bulk, the process is similar, but there are a couple of things you need to pay attention to. When you resize an image, you can also set custom dimensions each time, so it's up to you what sizes you want available more quickly.

You can change the existing presets or add a new one.


If you want to resize multiple images at once, there are some tools you can download to help you out with that. The two methods above work well if you just want to resize an image or two, but if you have a folder with a ton of large images, that's going to get tiring after a while. This is another easy method for resizing images, and it's the one I personally used most frequently for a long time.
