Khronos Texture is a container for textures for OpenGL/Vulkan/etc

KTX (Khronos Texture) is a lightweight container for textures for OpenGL(R), Vulkan(R) and other GPU APIs. KTX files contain all the parameters needed for texture loading. A single file can contain anything from a simple base-level 2D texture through to a cubemap array texture with mipmaps. Contained textures can be in a Basis Universal format, in any of the block-compressed formats supported by OpenGL family and Vulkan APIs and extensions or in an uncompressed single-plane format. Basis Universal currently encompasses two formats that can be quickly transcoded to any GPU-supported format: LZ/ETC1S, which combines block-compression and supercompression, and UASTC, a block-compressed format. Formats other than LZ/ETC1S can be supercompressed with Zstd and ZLIB.
