UIImage to String without converting JPG/PNG/HEIC

Question

Hello Gurus,
We would like to convert UIImage the raw binary data to string and reverse the string to UIImage object.

At most of the place we found below block.

Code Block extension String {
    func toImage() -> UIImage? {
        if let data = Data(base64Encoded: self, options: .ignoreUnknownCharacters){
            return UIImage(data: data)
        }
        return nil
    }
}

Is there any way to convert UIImage to String without converting JPG/PNG/HEIC ?

Have a look here:

When initialising a UIImage object with init(data: originalData), that originalData will be converted into raw data in some kind of internal format. These data can be retrieved later with
Code Block let rawData = myImage.cgImage?.dataProvider?.data as Data?
However because the rawData is raw, it is going to be even larger than when using UIImagePNGRepresentation.

Hope that helps.
