Convert Image to Base64 String in C#

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

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;
  }
}
