jpg to bw conversion can be done as a graphics export between JPEG (.jpg) and Silicon Graphics formats (.bw) using any graphics editor that supports BW files.
What some users may be looking for, though, is ways to convert color pictures to black and white (bw). This is not a file conversion per se, but applying a filter to the picture. Such a function is available in pretty much any decent graphics editor, and many online tools can be used for this as well.
