Converting Image to BASE64 String in swift

Question

I am trying to convert the Image which is picked by user either from his Photos or Take New from Camera. I am able to convert the image into base64 string but the problem is that it takes too much time and prints a long infinite string

Here is the output of String which i am getting

here is my code:

// Image picker from Gallery
    func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {
        imagePicker.dismissViewControllerAnimated(true, completion: nil)
        profileImage.image = image

    }

    // Image Picker from Camera

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
        imagePicker.dismissViewControllerAnimated(true, completion: nil)
        profileImage.image = info[UIImagePickerControllerOriginalImage] as? UIImage

        addPicBtn.setImage(nil, forState: .Normal)

        let imageData:NSData = UIImagePNGRepresentation(profileImage.image!)!
        let imageStr = imageData.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))
        print(imageStr)


    }

Since it is converting it is taking the time, it should not effect while uploading the image with base64 text. — Sachin Vas

Actually it will not take time to convert but for printing, it will take more time so don't print it...

but when i suppose to pick image from gallery, application holds there for a few mins

If you want less quality image than use UIImageJPEGRepresentation(imagePicked, 0.5)! than string value will come less, for loading use dispatch_async method and show loading spinner till image not come...

You can apply this code

let imageData: Data? = UIImageJPEGRepresentation(getImage(), 0.4)
let imageStr = imageData?.base64EncodedString(options: .lineLength64Characters) ?? ""
print(strBase64)

Swift 4 version. This simple func worked well for me. Confirmed decoded image back using this: https://codebeautify.org/base64-to-image-converter Hope this helps someone.

public static func  convertImageToBase64String(image : UIImage ) -> String 
{
    let strBase64 =  image.pngData()?.base64EncodedString()
    return strBase64!
}

Make sure your image extension first.

// .png

    guard let imageData = UIImagePNGRepresentation(UIImage) else {
        return ""
    }

// .JPEG

   guard let imageData = UIImageJPEGRepresentation(UIImage, 1) else {
                return ""
    }

// BASE 64

  imageData.base64EncodedString()

let imageData: Data? = UIImageJPEGRepresentation(YourImage, 0.4)
let imageStr = imageData?.base64EncodedString(options: .lineLength64Characters) ?? ""
print(imageStr,"imageString")
