Alamofire encodes the image in what format?

Question

I use alamofire to send an image to the server with multipart.

multipartFormData.append(UIImageJPEGRepresentation(self.imageDet[0].image!,0.5)!, withName: "filestream", mimeType: "image/jpeg") 

I have an image in byte format on the server side.

Here is an example of the bytes I get from the server side

How to convert the following data back to image?

Answer 1

Images are encoded in JPEG and converted to binary ( Data or NSData ) when writing UIImageJPEGRepresentation(...) . Then this binary data is sent to the server.
