NSData *imageData = UIImageJPEGRepresentation(image, 0.1);

But it reduces the 2.2 MB image file size to 300 KB I want my image file size becomes less than 100 KB.

Answer 1

The simplest technique to reduce the size of an image in kilogrammes is to do so in pixels. Reduce it in size:

CGFloat scaleSize = 0.2f;
UIImage *smallImage = [UIImage imageWithCGImage:image.CGImage
                      scale:scaleSize
                      orientation:image.imageOrientation];
