Mixing
Convert between UIImage and Base64 string
181
Does anyone know how to convert a UIImage to a Base64 string, and then reverse it?
I have the below code; the original image before encoding is good, but I only get a blank image after I encode and decode it.
NSData *imageData = UIImagePNGRepresentation(viewImage);
NSString *b64EncStr = [self encode: imageData];
NSString *base64String = [self encodeBase64:imageData];

Swift
First we need to have image's NSData
//Use image name from bundle to create NSData
let image : UIImage = UIImage(named:"imageNameHere")!
//Now use image to create into NSData format
let imageData:NSData = UIImagePNGRepresentation(image)!
//OR next possibility
//Use image's path to create NSData
let url:NSURL = NSURL(string : "urlHere")!
//Now use image to create into NSData format
let imageData:NSData = NSData.init(contentsOfURL: url)!
Swift 2.0 > Encoding
let strBase64:String = imageData.base64EncodedStringWithOptions(.Encoding64CharacterLineLength)
Swift 2.0 > Decoding
let dataDecoded:NSData = NSData(base64EncodedString: strBase64, options: NSDataBase64DecodingOptions.IgnoreUnknownCharacters)!
Swift 3.0 > Decoding
let dataDecoded : Data = Data(base64Encoded: strBase64, options: .ignoreUnknownCharacters)!
Encoding :
let strBase64 = imageData.base64EncodedString(options: .lineLength64Characters)
print(strBase64)
Decoding :
let dataDecoded:NSData = NSData(base64EncodedString: strBase64, options: NSDataBase64DecodingOptions(rawValue: 0))!
let decodedimage:UIImage = UIImage(data: dataDecoded)!
print(decodedimage)
yourImageView.image = decodedimage
Swift 3.0
let dataDecoded : Data = Data(base64Encoded: strBase64, options: .ignoreUnknownCharacters)!
let decodedimage = UIImage(data: dataDecoded)
yourImageView.image = decodedimage
Objective-C
iOS7 > version
You can use NSData's base64EncodedStringWithOptions
Encoding :
- (NSString *)encodeToBase64String:(UIImage *)image {
return [UIImagePNGRepresentation(image) base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
}
Decoding :
- (UIImage *)decodeBase64ToImage:(NSString *)strEncodeData {
NSData *data = [[NSData alloc]initWithBase64EncodedString:strEncodeData options:NSDataBase64DecodingIgnoreUnknownCharacters];
return [UIImage imageWithData:data];
}
iOS 6.1 and < version
First Option : Use this link to encode and decode image
Add Base64 class in your project.
Encoding :
NSData* data = UIImageJPEGRepresentation(yourImage, 1.0f);
NSString *strEncoded = [Base64 encode:data];
Decoding :
NSData* data = [Base64 decode:strEncoded ];;
image.image = [UIImage imageWithData:data];
Another Option: Use QSUtilities for encoding and decoding

SWIFT 3.0, XCODE 8.0
Replace String with your URL. and testImage is an outlet of ImageView
// Put Your Image URL
let url:NSURL = NSURL(string : "http://.jpg")!
// It Will turn Into Data
let imageData : NSData = NSData.init(contentsOf: url as URL)!
// Data Will Encode into Base64
let str64 = imageData.base64EncodedData(options: .lineLength64Characters)
// Now Base64 will Decode Here
let data: NSData = NSData(base64Encoded: str64 , options: .ignoreUnknownCharacters)!
// turn Decoded String into Data
let dataImage = UIImage(data: data as Data)
// pass the data image to image View.:)
testImage.image = dataImage
Hope It Helps Thanks.

In swift 2.0 use this extension (credit to Jonas Franz)
extension UIImage{
func toBase64() -> String{
let imageData = UIImagePNGRepresentation(self)!
return imageData.base64EncodedStringWithOptions(.Encoding64CharacterLineLength)
}
}

For Swift 2.2, .allZeros didn't compile. So I used return imageData.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))

var imageData: NSData

Swift version - create base64 for image
In my opinion Implicitly Unwrapped Optional in case of UIImagePNGRepresenatation() is not safe, so I recommend to use extension like below:
extension UIImage {
func toBase64() -> String? {
let imageData = UIImagePNGRepresentation(self)
return imageData?.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.Encoding64CharacterLineLength)
}
}

For iOS 7+, Objective-C, here's how to make the conversion starting with an image URL:
NSURL *url = [NSURL URLWithString:self.groove.thumbnailURL];
UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:url]];
NSString *base64String = [UIImagePNGRepresentation(image)
base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];

I tried all the solutions, none worked for me (using Swift 4), this is the solution that worked for me, if anyone in future faces the same problem.
let temp = base64String.components(separatedBy: ",")
let dataDecoded : Data = Data(base64Encoded: temp[1], options:
.ignoreUnknownCharacters)!
let decodedimage = UIImage(data: dataDecoded)
yourImage.image = decodedimage

You can use NSData's base64EncodedStringWithOptions
Encoding :
- (NSString *)encodeToBase64String:(UIImage *)image {
return [UIImagePNGRepresentation(image) base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
}
Decoding :
- (UIImage *)decodeBase64ToImage:(NSString *)strEncodeData {
NSData *data = [[NSData alloc]initWithBase64EncodedString:strEncodeData options:NSDataBase64DecodingIgnoreUnknownCharacters];
return [UIImage imageWithData:data];
}
iOS 6.1 and < version
First Option : Use this link to encode and decode image
Add Base64 class in your project.
Encoding :
NSData* data = UIImageJPEGRepresentation(yourImage, 1.0f);
NSString *strEncoded = [Base64 encode:data];
Decoding :
NSData* data = [Base64 decode:strEncoded ];;
image.image = [UIImage imageWithData:data];
Another Option: Use QSUtilities for encoding and decoding

First we need to have image's NSData
//Use image name from bundle to create NSData
let image : UIImage = UIImage(named:"imageNameHere")!
//Now use image to create into NSData format
let imageData:NSData = UIImagePNGRepresentation(image)!
//OR next possibility
//Use image's path to create NSData
let url:NSURL = NSURL(string : "urlHere")!
//Now use image to create into NSData format
let imageData:NSData = NSData.init(contentsOfURL: url)!

SWIFT 3.0, XCODE 8.0
Replace String with your URL. and testImage is an outlet of ImageView
// Put Your Image URL
let url:NSURL = NSURL(string : "http://.jpg")!
// It Will turn Into Data
let imageData : NSData = NSData.init(contentsOf: url as URL)!
// Data Will Encode into Base64
let str64 = imageData.base64EncodedData(options: .lineLength64Characters)
// Now Base64 will Decode Here
let data: NSData = NSData(base64Encoded: str64 , options: .ignoreUnknownCharacters)!
// turn Decoded String into Data
let dataImage = UIImage(data: data as Data)
// pass the data image to image View.:)
testImage.image = dataImage
Hope It Helps Thanks.

Swift 3.0
To convert image to base64 string
Tested in playground
var logo = UIImage(named: "image_logo")
let imageData:Data = UIImagePNGRepresentation(logo)
let base64String = imageData.base64EncodedString()
print(base64String)

In swift 2.0 use this extension (credit to Jonas Franz)
extension UIImage{
func toBase64() -> String{
let imageData = UIImagePNGRepresentation(self)!
return imageData.base64EncodedStringWithOptions(.Encoding64CharacterLineLength)
}
}

For Swift 2.2, .allZeros didn't compile. So I used return imageData.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))

let imageData:NSData = UIImagePNGRepresentation(userImage)! as NSData
let dataImage = imageData.base64EncodedString(options: .lineLength64Characters)
Decoding :

Swift version - create base64 for image
In my opinion Implicitly Unwrapped Optional in case of UIImagePNGRepresenatation() is not safe, so I recommend to use extension like below:
extension UIImage {
func toBase64() -> String? {
let imageData = UIImagePNGRepresentation(self)
return imageData?.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.Encoding64CharacterLineLength)
}
}

For iOS 7+, Objective-C, here's how to make the conversion starting with an image URL:
NSURL *url = [NSURL URLWithString:self.groove.thumbnailURL];
UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:url]];
NSString *base64String = [UIImagePNGRepresentation(image)
base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];

I tried all the solutions, none worked for me (using Swift 4), this is the solution that worked for me, if anyone in future faces the same problem.
let temp = base64String.components(separatedBy: ",")
let dataDecoded : Data = Data(base64Encoded: temp[1], options:
.ignoreUnknownCharacters)!
let decodedimage = UIImage(data: dataDecoded)
yourImage.image = decodedimage
