Notes:
The following table provides the supported texture formats for the Web platform.
Format | Description |
---|---|
ASTC | Adaptive Scalable Texture Compression3D Graphics hardware requires Textures to be compressed in specialized formats which are optimized for fast Texture sampling. More info See in Glossary (ASTC) is an advanced lossy texture compression format. Widely used for mobile browsers / devices. |
DXT | Also known as S3 Texture Compression (S3TC), DXT is mainly used for desktop browsers and devices. |
ETC2 | Ericsson Texture Compression (ETC) is an older lossy texture compression format, lower quality than ASTC, used for mobile browsers / devices. |
