Ultimate Compression System – Unity Project Size Optimizer

Overview

The Ultimate Compression System is a comprehensive Unity Editor extension designed to help developers drastically reduce their project size without sacrificing quality. Whether you're developing for mobile, desktop, or web platforms, this tool provides a complete suite of compression and optimization features to streamline your workflow and deliver smaller, faster, and more efficient builds.

Why Use This Tool?

Large project sizes can lead to longer build times, sluggish performance, and bloated app sizes that frustrate players and developers alike. This tool addresses those issues with automated optimization workflows, selective compression features, and real-time feedback—making your project lighter, faster, and ready for deployment.

Key Features -

• Quick Optimize (One-Click Compression)

Optimize your entire project in seconds with a single button. This feature runs all core optimizations and provides a Before & After size comparison, helping you monitor the storage savings in real time. Optional toggles allow you to exclude specific optimization steps.

• Texture Compression

Automatically compress all textures using Unity’s built-in compression methods. It detects uncompressed textures and applies the most efficient format, reducing size significantly while maintaining visual fidelity.

• Audio Compression

Convert all audio clips to Vorbis format and adjust compression quality on the fly. Optionally force audio files to mono, helping mobile and web builds shrink even further.

• Mesh Optimization

Apply mesh compression settings to all 3D models, reducing their size and memory footprint. Supports automatic LOD (Level of Detail) generation, improving runtime performance while cutting build size.

• Sprite Atlas Compression

Optimize Sprite Atlases by applying texture compression and disabling unnecessary mipmaps. Perfect for UI-heavy projects.

• Build Size Report

Instantly generate a detailed report showing your largest assets by size, before and after compression. Identify heavy assets and focus your optimization efforts where they matter most.

• Remove Unused Assets

Scan your project for unused files and assets and safely remove them. Keep your project clean and efficient.

• Shader Variant Stripping

Clear unused shader variants from shader collections, reducing build times and minimizing final shader data.
