How to compress image to a target size (not CGSize) like 10MB to 9MB? Do I have to resize the image? Tried UIImageJPEGRepresentation, not very useful.

To decrease image size, you must decrease its size or Quality. for quality you can use UIImageJPEGRepresentation with quality in second parameter.

to downscale you can use code from this link: http://stackoverflow.com/questions/29137488/how-do-i-resize-the-uiimage-to-reduce-upload-image-size
