packXXX XXL update

packJPG, packMP3, packPNM, packARI, packHUF, packLZH and unpackJPG are now updated with new contact information and some minor bugfixes. This step was required because the original home of packJPG on the HTW Aalen University website is closing soon (granted, that website is severely outdated now, too). With the original website closing, my original contact adress on the HTW Aalen email domain won’t work anymore, too.

If you haven’t updated my contact info yet, you may contact me anytime via

We are now on GitHub!

Needless to say, this step was long overdue. You may now download all of my source codes, follow my development, fork my software and collaborate with me on my official GitHub repo.

This blog will still get updated, but only with public releases.

packJPG & packMP3 Options by Michael Lee

Developer Michael Lee discontinued (most of) his Photo Tools page. This includes the official downloads of packJPG Options and packMP3 Options, which are excellent graphical user interfaces for packJPG and packMP3.

You may find the downloads for most recent versions of both tools in the packJPG and packMP3 sections of this page now. While you’re at it, you might also give Michael’s excellent GPStamper tool a try.

On another, slightly related note, expect the LGPL release of packMP3 and packARC soon!

packJPG v2.5j update

Just a very minor update:

packJPG v2.5j

I did some source code optimizations and also fixed some possible (although, in reality: almost impossible) memory leaks. Thanks go to Roger Sibert for recommending CPPcheck, which enabled me to do so.
