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.
