How can I quickly and easily crop images on a Mac?

Question

macOS

You need to be able to quickly crop the size of photos in a folder. If there are photos with a size of under 5Mb each and 4000x3000 pixels, or how many there are on 16MP cameras, then I want to be able to easily select them all and crop the pixels - make them 1024x768 in size. To weigh less before uploading to the site or social. networks.
On Linux there is gThumb, where this is done easily. And on the Mac?
Maybe there is some kind of console utility? It will be even better for me.
I also have GIMP, but it's heavy, running it for each photo, cropping it, then exporting the photo is a long time.

Open the picture with a regular viewer and take a screenshot of the screen. You can immediately select the area that you want to screenshot so that unnecessary elements do not get into it.
