Editing JPEG DPI without resampling

The title is the naive search term for a problem. The good search term - or Google power phrase - is Exif editor. The best of the results which simply solves the problem is the Exif Pilot on an Exif editors page. Enjoy!

P.S.: I decided to publicate the fruit of every hard and exhausting search on this blog. Maybe it is not good for the regular visitor, but I'm sure it helps the Universe in general. :-)
