This tool can optimize your Minecraft Java mod size (and performance) by up to 50%!

• Advent Of Ascension: 85. 9MB -> 46.4 MB (-46%)!
• Ore Spawn: 16.7 MB -> 7.6 MB (-54.5%)!
• Biomes O'Plenty: 3.1 MB -> 2.0 MB (-35%)!

The android application lowers the requirements for playing Minecraft modpacks:

• Smaller file sizes, resulting in lower memory usage, lower VRAM usage, and faster startup times.
• Lower CPU usage when playing sounds and loading textures.

Yes!! I personally use this in all my modpacks to allow them to run on my lower-end hardware (limited RAM, integrated graphics...).

However, you should consider some other optimizations before doing using this tool, such as:

• Remove useless mods
• Tweak config files
• Use performance-enhancing mods
• Using the latest java for your minecraft version
• And other miscellaneous Windows 10 Optimizations (you can find plenty of guides online)

First, almost all textures in Minecraft Java mods use the .PNG format. This tool uses the fantastic PNGQuant software to optimize all textures.

Second, almost all sounds are stored at the .OGG format using the Vorbis codec. For these, the tool uses a custom build of FFMPEG to cut out really high frequencies and save space.

Finally, some more recent mods make heavy use of JSON files. These can be trimmed down as well.

Simply launch the app, select your mod(s), and click Optimize! The application will do everything for you.
You'll be able to see the progression of each step with the various progress bars.

I'm developing on Linux (lubuntu if you're curious) so I don't know if it will work on Mac OS, and it does not work on Windows.

Things I should do that I surely won't.

• Make the app compatible with API 21 instead of 24.

• StackOverflow for helping me to learn Java ^^'
• Kornelski for PNGQuant and ndahlquist for the android implementation
• Tanersener for mobile-ffmpeg
• Charlesbihis for the Json minifier
• SylveonBottle for proof-reading and updating the optimization list
• SerpentSpirale for this app!

And of course, thanks to all contributors of all of those projects!
