Unity Build Optimization Checklist: Reduce Size & Improve Store Approval
Unity Build Optimization Checklist
Large builds hurt:
- Download conversion
- WebGL load time
- Store approval
- User experience
Let's reduce build size properly.
Enable Code Stripping
Player Settings:
- Managed Stripping Level → Medium/High
- Strip Engine Code → Enabled
Reduces unused assemblies.
Remove Unused Assets
Delete:
- Demo scenes
- Unused prefabs
- Placeholder assets
- Asset Store leftovers
Clean projects build smaller.
Compression Settings
Use:
- Brotli (WebGL)
- LZ4/LZ4HC (Mobile)
Compression improves delivery.
Optimize Audio
- Use compressed formats
- Reduce bitrate
- Remove unused clips
Audio bloats builds quickly.
Final Thoughts
Smaller builds improve:
Install rate. Load speed. Player satisfaction.
Optimization = professionalism.
