RPGMakerCompressor

RPGMakerCompressor is a console-based application used to compress RPG Maker MV/MZ game assets.

It uses lossy compression with conservative parameters to reduce file size while minimizing noticeable visual and audio quality loss.

Features

• Compresses image and audio assets
• Supports RPG Maker MV/MZ (Perhaps more in the future.)
• Designed for good compression with minimal quality loss

Usage

1. Launch the application
2. On first launch, required dependencies will be downloaded automatically
3. Restart the application once setup is complete
4. Provide the path to your RPG Maker MV/MZ game

Installing Compressed Assets

After compression:

1. Navigate to your game's www folder
2. Delete the original img and audio folders
3. Copy the compressed files from the Output folder
4. Overwrite files if prompted

Dependencies

These dependencies are automatically downloaded on first launch:

• RPGMakerDecrypter (fork) - Decrypting of RPG Maker game files
• FFmpeg — Audio processing
• oxipng — PNG optimization
• pngquant — Lossy PNG compression

Notes

• Dependencies are downloaded as prebuilt binaries from their official sources
• No dependencies are bundled with the GitHub release
