I’d like to open a .jpg file in WPF, scale it down to around 50%, then save it back to the file system. What’s a good/efficient way to go about doing that?

If you want to save on the memory usage you should look into specifying DecodePixelWidth/DecodePixelHeight on BitmapImage or the JpegDecoder.
The scaling can be accomplished using TransformedBitmap.
