gif2apng is a simple command-line program that converts GIF animations into Animated PNG format. It disproves the common misconception that APNG files must be huge, as it actually creates APNG files smaller than the original GIF files. The program is very easy to use.

Command line: gif2apng.exe anim.gif [anim.png]
