How Does Image Previes in IOS determine resolution of an image?

I am under the impression that JPEGs cannot store resolution/DPI/density information. How is it possible that iOS Image Preview is able to provide resolution per image attached?

The reason I ask is that I need to alter the resolution to a specific number so that when I send the image to a 3rd party API, they know how many pixels per inch to print. I only allow image uploads in JPEG/PNG format.

Any solutions in javascript would be greatly appreciated

Thanks! enter image description here

You have to change the values from pixels to inches and then set the dimensions. The resolution for full hd images is 1024 or 720 pixels per inch
