Decode Base64 encoded String back to a byte arrayīyte decodedImageBytes = Base64.getDecoder().decode(base64EncodedImageBytes) String base64EncodedImageBytes = Base64.getEncoder().encodeToString(imageBytes) ![]() Encode image bytes to Base64 encoded String Throw new IllegalArgumentException("Image does not exist at the specified path") īyte imageBytes = Files.readAllBytes(pathToImage) Path pathToImage = Paths.get(imageFilePath) String imageFilePath = "/Users/sergeykargopolov/Downloads/Design_2-01.png" Convert Image to a Base64 Encoded Stringīelow is a complete code example that demonstrates how to read image bytes into an array of bytes and then convert this array of bytes into a Base64 encoded string. Let’s have a look at a complete code example. byte decode = Base64.getDecoder().decode(base64EncodedString) To do that you will use the Base64.getDecoder().decode() method. String base64EncodedImageBytes = Base64.getEncoder().encodeToString(bytes) Decode Base64 String into byteĮventually, you will need to decode the Base64 encoded string of characters back into a byte. To do that, you can use the Base64 class from java.util package. Once you have an array of bytes, you can easily convert it into a Base64 encoded string. byte bytes = Files.readAllBytes(pathToImage) Convert byte to a Base64 Encoded String ![]() ![]() Since the image is just a file, we can use the Files class in Java to read image bytes into an array. Our task is to first convert this image into a byte array. Let’s assume that we have an image on our computer.
