You can use LEADTOOLS Imaging Pro SDK technology in your application.
https://www.leadtools.com/sdk/products/imaging-pro
You can leverage the RasterCodecs class, to save an image, of any LEADTOOLS supported raster format, to a MemoryStream.
Here is some sample code:
using (RasterCodecs _codecs = new RasterCodecs)
using (RasterImage _image = _codecs.Load(@"FILE PATH TO INPUT IMAGE"))
{
    MemoryStream ms  = new MemoryStream();
    _codecs.Save(_image, ms, RasterImageFormat.Jpeg, 0);
    byte[] _imageArray = ms.ToArray();
}

Convert image to byte[]array:
public byte[] imageToByteArray(System.Drawing.Image imageIn)
{
    MemoryStream memorys = new MemoryStream();
  imageIn.Save(memorys,System.Drawing.Imaging.ImageFormat.Gif);
  return memorys.ToArray();
}
This method uses the System.Drawing.Image.Save method to save the image to a memorystream. The memorystream can then be used to return a byte array using the ToArray() method in the MemoryStream class.

Convert byte[] array to Image:
public Image byteArrayToImage(byte[] byteArrayIn)
{
   MemoryStream memorys = new MemoryStream(byteArrayIn);
      Image returnImage = Image.FromStream(memorys);
   return returnImage;
}
This method uses the Image.FromStream method in the Image class to create a method from a memorystream which has been created using a byte array. The image thus created is returned in this method.

Converting using MemoryStream.
public byte[] ImageToByteArray(System.Drawing.Image imageIn)
{
   using (var ms = new MemoryStream())
   {
      imageIn.Save(ms,imageIn.RawFormat);
      return  ms.ToArray();
   }
}
Converting using ImageConverter.
public static byte[] converterDemo(Image x)
{
    ImageConverter _imageConverter = new ImageConverter();
    byte[] xByte = (byte[])_imageConverter.ConvertTo(x, typeof(byte[]));
    return xByte;
}
Covnerting from using path
byte[] imgdata = System.IO.File.ReadAllBytes(HttpContext.Current.Server.MapPath(path));
