How to crop a photo?

Question

PHP

Hello. I decided to do photo compression on gmagick.

Question: how to make it possible to select the area you need with a square in the photo and save it? Like vkontakte Are there ready-made solutions, maybe choose imagemagick? If you do it in js, then you can change everything on the client side.

And on the server side, I use only js. More specifically, node.js. I ask for help
