Jpeg is a lossy algorithim.
Check out this very nerdy site for more data....

My understanding, from various people at Leica, is that the M8's
compression is a lossless one. The DMR (essentially the same size
sensor) delivers a 19.5mb file. The M8 delivers a compressed, 10.3mb
file, if I recall correctly. That is about a 47% compression...
close the limit of various lossless compression techniques. If it
were a lossy compression, such as .jpg, it could drop the file to a
meg or two, but with a great loss of information.
Cheers!
