I am trying to compress an image using following method

jpegData(compressionQuality:)

In this case image got compressed but the resolution of an image also got changed. But i actually want only image will compress without changing the resolution. Please suggest the possible solutions.

    If you need compression, you will have to forget about the resolution. Without lowering the resolution you can't compress. – nayem Dec 10 '18 at 09:09
  • Did you figure out the reason and a solution? Facing the same issue that `jpegData(compressionQuality:)` seems to apply screen scale to the resolution – hyouuu Feb 06 '20 at 05:16

extension UIImage {

    public func base64(format: ImageFormat) -> String? {
        var imageData: Data?
        switch format {
        case .png: imageData = UIImagePNGRepresentation(self)
        case .jpeg(let compression): imageData = UIImageJPEGRepresentation(self, compression)
        }
        return imageData?.base64EncodedString()
    }
}

use this extension to compress the image, i have been using this extension from a long time, try it if it does not affect the resolution.
