        JPEG image is compressed file format. You need to decompress it first and then use it. Look here[^] for compression and decompression algorithms. Regards, Paresh.

          If you are using GDI+, it is easy. Load the image using GDI+, and save as "JPEG" with the compression required. GDI+ supports BMP, PNG, TIF, JPG, GIF. Make sure you initialize GDI+ first and use the encoders. The following MSDN doc shows how to load BMP and save to PNG. With minor changes, your can save to JPG http://msdn2.microsoft.com/en-us/library/ms533837.aspx
