I have a image upload app for iOS. It works but 1 problem which I couldn’t find.

When you select a photo from the photolib the file size is +- 100kb but if you use your camera and make a picture the file size is a few MB. How can I change the file size without losing quallity or without changing the size of the image?

    There is a way to keep the same size while just losing imperceptible quality.

    Use:

    UIImageJPEGRepresentation(image, 0.6);
    

    You can increase quality and size by increasing from 0.6 to 0.8 etc. (As long as it’s a value between 0 and 1)

    I believe that the camera roll does this for you, which is why they are in the 100kb range already.
