APNG Assembler has already been mentioned at The APNG format forum thread by billon and webfork. For me this program is extremely useful and I think it deserves it own forum thread and submission to the database. I am reviewing the GUI version of APNG Assembler.
Synopsis
FeaturesAPNG Assembler creates APNG animation from PNG/TGA image sequence.
A number of optimization techniques used to make APNG files as small as possible: inter-frame optimization utilizing alpha-blend and dispose operations, smaller than the full-size subframes, dirty transparency, color type and palette optimizations, and various compression options: zlib, 7zip, Zopfli.
Command-line version is available for all major OSes, as well as GUI version for Windows. C++ source code is available under zlib license
Command line: apngasm output.png frame001.png [options]
Command line: apngasm output.png frame*.png [options]
LinksOptions:
1 10: frame delay is 1/10 sec. (default)
-l2: 2 loops (default is 0, forever)
-f: skip the first frame
-kp: keep the original palette, do not optimize it.
-kc: keep the original PNG color type, do not optimize it.
-z0: zlib compression
-z1: 7zip compression (default)
-z2: Zopfli compression
-i##: number of iterations (default -i15) for 7zip and Zopfli

Portability
APNG Assembler is portable and stealth- it saves no settings.
Instructions
- Download either the x32 archive (apngasm_gui-2.91-bin-win32.zip) or the x64 archive (apngasm_gui-2.91-bin-win64.zip);
- Extract the archive to a folder of your choice;
- Run either the x32 executable (apngasm_gui.exe) or the x64 executable (apngasm_gui64.exe);
I suppose that APNG Assembler should work under all Windows versions from XP to 10.

APNG Assembler is licensed under zlib License.
Note
The input PNG files should have the same dimensions.
The developer's e-mail address can be found in the readme.txt included in the archives.
