Game texture optimizer: find the work worth doing first.

Analyze a complete texture set or ZIP

Choose the real source files instead of entering every width, height, quantity, format, and mip setting by hand. The browser tool reads supported image headers, expands ZIP entries locally, hashes exact duplicates, samples decoded alpha where supported, and calculates each mip level with GPU block rounding.

• Download size and expanded source bytes
• RGBA8-equivalent uncompressed GPU memory and exact mipmap overhead
• Desktop, Mobile, and VR / Quest recommendations
• BC1, BC3, BC5, BC7, ASTC, ETC2, and KTX2 transcode comparisons
• Unused alpha, duplicate, oversized-map, normal-format, and ORM packing checks

Run Game Texture Optimizer

What can a game texture optimizer detect automatically?

The analyzer can detect exact duplicate files, alpha channels that appear unused, utility maps that are larger than the target preset needs, normal maps stored as general RGBA textures, non-power-of-two dimensions, and compatible occlusion, roughness, and metallic maps that can share one RGB texture.

Optimize by measurable savings instead of habit

The recommendation rail keeps each action tied to estimated bytes. That makes it easier to prioritize a duplicate 4K map over a tiny format cleanup that will not move the budget.

1. Remove exact waste. Duplicates and unused alpha are usually the lowest-risk first actions.
2. Reduce low-information maps. Masks and utility data often tolerate lower resolution than the visible color texture.
3. Pack and compress by role. Combine compatible scalar channels and use a normal-specific format where the target supports it.
