WebGL Unity optimizer
The WebGL Unity optimizer is an open-source utility created by us. Its purpose is to tweak various Unity settings and help you optimize the assets, so you get a bundle as low as possible, with the highest performance. You can find the Utility as a separate project on GitHub. It also comes integrated by default in our SDK, so you don't have to download it as a separate package.
Once you have imported our SDK in Unity, or the utility from GitHub, it will be accessible via this menu option:

Export settings
The export settings tab will help you tweak various settings that will make your game more performant, or decrease the final build size.

Texture optmizer
The texture optimizer utility gives you an overview of all the textures in your project and provides some tips about decreasing their size.
