That is, after you run the command on an image, it will be permanently resized. In my experience though, sips does quite a good job of resizing the images and the quality definitely rivals commercial tools such as Photoshop.

How to Resize Multiple Images At Once on Your Mac
That will change the dimensions of the image, perhaps you need the width to be the same as the width of a webpage you are adding the image to, for example. But what if it's the size of the image - in terms of MB - you want to change? If you are trying to make the size of the image smaller perhaps so you can send it via email there are a couple of ways you can do so.
If you open the Adjust Size menu as above you will notice that when you adjust the dimensions of the image you will see a preview of the size in MB or KB of the image before and after you have make your changes.
It may take a while to calculate the size. If you are trying to shrink the image to KB for example, you can keep adjusting until you are happy with the result here. Who knew.
