Convert Image to Base64 String and Base64 String to Image

This article will help you to learn how we can convert an image into a base64 string and base64 string back to image.

Image to Base64 String

public string ImageToBase64(Image image, System.Drawing.Imaging.ImageFormat format)
{
  using (MemoryStream ms = new MemoryStream())
  {
    // Convert Image to byte[]
    image.Save(ms, format);
    byte[] imageBytes = ms.ToArray();

    // Convert byte[] to Base64 String
    string base64String = Convert.ToBase64String(imageBytes);
    return base64String;
  }
}

Base64 String to Image

public Image Base64ToImage(string base64String)
{
  // Convert Base64 String to byte[]
  byte[] imageBytes = Convert.FromBase64String(base64String);
  MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length);

  // Convert byte[] to Image
  ms.Write(imageBytes, 0, imageBytes.Length);
  Image image = Image.FromStream(ms, true);
  return image;
}
