    PNG to JPG Help Please

    I am trying to convert some PNG files to JPG files, everything works fine i just need to keep the transparency for the backgrounds or make them white/colorless. i tried using the options in the batch conversion section with no success.
    Thank you in advance

    IrfanView unfortunately makes transparent areas black in batch conversion. I would use the command line instead, which is more like Save. You can do several (even unique) files at once, this way. Just make sure the viewer is set to have a white background.

    i_view32.exe "C:\drawing*.png" /convert="C:\Converted\$N.jpg"

    or

    i_view32.exe /filelist=C:\Myimages.txt /convert="D:\temp\*.png"

      The JPG format cannot represent transparency!
      To use transparency you must take the PNG or the GIF format!

      With the JPG format you can only use the little trick of Skippybox!

        How do you use or get to the command line?
        thank you
