Unity WebGL Performance Guide: Reduce Load Time & Memory Usage
Unity WebGL Performance Optimization
WebGL has strict constraints.
High memory = crash. Large builds = drop-off.
Reduce Build Size
- Remove unused assets
- Enable code stripping
- Use Brotli compression
- Lower texture resolution
Memory Discipline
WebGL memory is fixed.
Avoid:
- Large texture arrays
- Runtime allocations
- Heavy physics systems
Profile early.
Load Strategy
Use:
- Splash screen preload
- Async loading
- Addressables
Reduce first-interaction friction.
Final Thoughts
WebGL success depends on: Optimization discipline. Minimalism. Efficient architecture.
