About ETC1 Compression

ETC1 (Ericsson Texture Compression 1) is a lossy GPU texture compression format widely used in mobile games and applications.

📱 Android Support

ETC1 is supported on all OpenGL ES 2.0+ devices, making it ideal for Android games with broad compatibility.

🎲 Power of Two

For best GPU performance and driver compatibility, ETC1 textures should have power-of-two dimensions (64, 128, 256, 512, 1024, 2048).

🔴 No Alpha Support

ETC1 only supports RGB (no alpha channel). For transparency, use ETC2 (requires OpenGL ES 3.0) or split alpha into separate texture.

💼 6:1 Compression

ETC1 compresses textures to 0.5 bytes per pixel (vs 3 bytes for RGB), reducing GPU memory usage significantly.
