💡 Why use this?

Optimizing build size and runtime memory often requires setting platform-specific overrides. Doing this manually for every texture is a nightmare.

This tool solves the common problem:

"I want all my opaque background textures to use RGB ETC2 4-bit, but all my transparent UI icons to use RGBA ETC2 8-bit, and I want them all max 2048px on Android."

OneClick Texture Optimizer does exactly that in one click.
