Changing the colour depth of a bitmap when saving

I need to change the colour depth (or PixelFormat) of a bitmap before I save it to a file. I'm guessing it's something to do with EncoderParams, but i'm not having much luck with them...

The bitmap starts off as: PixelFormat.Format32bppArgb

Thanks in advance

Create another bitmap with same size, and required pixel format. Then create Graphics object from destination bitmap using Graphics.FromImage method, and draw in it source bitmap using Graphics.DrawImage method. This copies source bitmap to destination. Save destination bitmap to file.
