ktx-tools

KTX (Khronos Texture) is a lightweight container for textures for OpenGL®, Vulkan® 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. This software package contains: - libktx: a small library of functions for writing and reading KTX files, and instantiating OpenGL®, OpenGL ES™️ and Vulkan® textures from them. - ktx2check: a tool for validating KTX Version 2 format files. - ktx2ktx2: a tool for converting a KTX Version 1 file to a KTX Version 2 file. - ktxinfo: a tool to display information about a KTX file in human readable form. - ktxsc: a tool to supercompress a KTX Version 2 file that contains uncompressed images. - toktx: a tool to create KTX files from PNG, Netpbm or JPEG format images. It supports mipmap generation, encoding to Basis Universal formats and Zstd supercompression.
