You can find Cropper options here.
The max_width and max_height options are used to define maximum size the cropped uploaded image will be.
Bigger images (after cropping) are scaled down.
Security Note: NEVER rely on this size constraints and the format settings as they can be easily manipulated client side. ALWAYS validate the image-data, -size, -format at server side!
