Questions & Answers
KTX2 images: Frequently Asked Questions
What are KTX2 files?
KTX2 (Khronos Texture 2.0) is a texture container format developed by the Khronos Group for storing images intended for use by a graphics processing unit. It can contain mipmap levels, cubemap faces, texture arrays and volume textures in one file, along with a data format descriptor and key-value metadata describing color space, orientation and other properties. KTX2 files often use Basis Universal supercompression, which keeps the file small and lets the texture be transcoded at runtime into the block-compressed format supported by the hardware, such as BCn, ETC or ASTC. Because of this portability, KTX2 is widely used in glTF models, WebGL and WebGPU applications, and modern game pipelines.
