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the original home of packJPG on the HTW Aalen University website is closing soon (granted, that website is severely outdated now, too).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.

packARC v0.7RC17 update

Incorporating the new LGPL licensed packMP3 library, packARC (with packMP3 support!) is now also licensed under the LGPL. The other major change in this version is the inclusion of the MultiArc friendly list format, a modification that was requested by Pavel Krejčí. Get it from the usual place:

packARC v0.7RC17

What’s new:

  • updated packMP3 library to new version (now licensed under LGPL v3)
  • packARC is now open source under the terms of the LGPL v3
  • added MultiArc friendly file list format
  • some minor bugfixes

For anyone looking to add packARC support to non GPL projects, the new licensing under the LGPL should be quite a big change.

packMP3 v1.0f update

… and here it is: packMP3, finally released under the LGPL v3 (formerly: GPL v3). Other than this major licensing change, very little has changed for the packMP3 source code itself.

packMP3 v1.0f

What’s new:

  • packMP3 licensing changed to LGPL v3
  • some minor bugfixes

This update should mainly be interesting to anyone looking to add PMP compatibility to a non GPL software project. Keep in mind that also with the LPGL licensing you’ll need to keep the packMP3 code apart from the rest from your code (for non GPL projects) and you’ll also have to release any modifications of the code back to the general public.

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!

Comment Spam

During the last few weeks this page experienced what I see as a particularly bad case of comment spamming. You should be seeing nothing, as all these comments are still in my review folder. They have by now only been partially reviewed and there are still 4000+ left to go, of which ~99.9% is spam.

If you have written an actually useful comment and it got/gets caught up in my cleanup frenzy: Sorry! I’m already using Akismet for spam protection (activated it today), but it still seems like an impossible task to review all these comments. If you got an idea how to solve this please write a comment below this post.



packLZH v0.4a slip-up

If you have actually downloaded packLZH v0.4a earlier, you need to download again. A minor code change led to major consequences in the version online for the last few hours. If you download now everything will be okay.

Download packLZH v0.4a here!

Upload limit increased: now content-complete

The upload limit was increased thanks to the amazing folks at This finally enabled me to properly upload all my stuff to this place, meaning that this is now complete contentwise. I still intend to do some fine tuning and maybe I’ll find some other interesting stuff to upload to this place.

More stuff and still some trouble

I’ve added even more stuff for you and reorganized some things. There’s still trouble with uploading larger files and I still can’t get that contact form to work. So, this is still only almost complete contentwise.

More progress

Well, look at that. This place is now, regarding content, almost complete. There’s still some stuff that needs work, and some files could not yet be uploaded due to size restrictions. More later.
