How to change what part of an image is visible

Hey guys,

How do I change which part of an image is visible on my page without losing resolution? For example, instead of this:

https://michaelm856.sg-host.com/wp-content/uploads/2024/02/IMG_1448.jpeg

I want to crop some part of the image so only part of it is visible.

By the same token, is there a way to change where the centre point of the image is?
