Because there the files are used unchanged. With createFromImage they are decompressed and recompressed with the Flate filter, this is a lossless compression. I am surprised that the original JPEG would be 794 kb and the PDF 766 kb. The PDF shouldn't be smaller than the image. Please upload both files on a sharehoster for analysis.
