## What it is
The official Khronos KTX library and tools for reading, writing, and transcoding KTX texture container files used with OpenGL, Vulkan, and other GPU APIs. It supports block-compressed and Basis Universal formats with supercompression, and ships CLI tools plus WebAssembly/JavaScript wrappers.

## Use cases
- load compressed textures in a Vulkan renderer
- convert PNG textures to KTX2 with Basis Universal compression
- transcode textures to GPU-specific compressed formats at runtime
- package cubemap arrays with mipmaps into a single texture file
- reduce texture memory in a WebGL game with compressed formats

## When to choose
- you need a standard, GPU-friendly texture container for OpenGL/Vulkan/WebGL
- you want Basis Universal transcoding to any GPU-supported format
- you need cross-platform texture tooling including web/wasm

## When to avoid
- you only need simple image editing or format conversion between PNG/JPEG
- your engine already has its own proprietary texture pipeline
- you need runtime texture authoring rather than loading

## Facets
- artifact type: library
- maturity: active
- function: image-processing, graphics, compression, sdk
- domain: graphics, cross-platform
- platform: cpp, cross-platform, wasm, windows
- tags: ktx, textures, gpu-textures, basis-universal, vulkan, opengl, texture-compression, game-development, android, ios, linux, macos
