Converting an Image to Data and Vice Versa [closed]
Swift 5.1 or later
To convert from UIImage to Data you can use UIImagePNGRepresentation or UIImageJPEGRepresentation if you need to reduce the file size.
extension UIImage { var jpeg: Data? { jpegData(compressionQuality: 1) } // QUALITY min = 0 / max = 1 var png: Data? { pngData() } }To convert back to Image from Data you just need to use UIImage(data:) initializer:
extension Data { var uiImage: UIImage? { UIImage(data: self) }}Playground
let image = UIImage(data: try! Data(contentsOf: URL(string: "https://i.stack.imgur.com/Xs4RX.jpg")!))!if let jpegData = image.jpeg { print(jpegData.count) // 416318 number of bytes contained by the data object if let imageFromData = jpegData.image { print(imageFromData.size) // (719.0, 808.0) }}if let pngData = image.png { print(pngData.count) // 1282319 if let imageFromData = pngData.image { print(imageFromData.size) // (719.0, 808.0) }}
