JPEG

I saved a 1x1 white pixel jpeg at highest compression with photoshop and it ended up being 8KB. After opening it up with a hex editor I was able to get rid of 7KB of extraneous junk. So is there a way to get photoshop not to add crap? or is there a program out there that will remove this stuff by the batches?

I hand code my jpegs in a hex editor. Draw out my Huffman trees on napkins. Just can't trust something important like image compression to a computer program.
