Memory SizeStart at 256 MB, raise only if needed
iOS is hard

Unity WebGL games are disabled on iOS by default because of memory crashes. Once your game proves stable on desktop and Android, it gets enabled. Keep peak memory low.

Optimization checklist​

  • Compress textures to ASTC/ETC
  • Use Resources sparingly — prefer Addressables
  • Strip unused shaders
  • Disable physics layers you don't need
  • Enable IL2CPP code stripping
