What is a .KTX file?
KTX stores GPU textures ready for OpenGL and Vulkan. Standardised by the Khronos Group.
- Did you know
- KTX holds textures in formats the graphics card can use directly, mipmaps and all.
- The original KTX specification came from the Khronos Group’s OpenGL ES working groups as a container for GPU-ready textures.
- A single KTX file can hold anything from a plain 2D image to a full cubemap array, complete with all its mipmap levels.
- What Analyser reads
- Inspect game ROMs, patches and engine assets: iNES/NES2.0, Game Boy/Color/Advance, SNES, Nintendo DS/DSi, Nintendo 64, and Sega Genesis ROM headers (title, mapper, region, checksum); IPS/BPS/UPS/PPF patches; Doom WAD lumps; Minecraft NBT/schematics and Bedrock bundles; Aseprite sprites; Godot .pck; Quake/id Tech PAK/PK3; Source BSP/VPK/VTF/VMT; KTX/KTX2 textures; Tiled maps; LÖVE games; PICO-8 carts - plus MPQ, 3DS/Switch and Ren’Py/RPG Maker identification.
- Depth of analysis
- .KTX is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .KTX file
- Drag a .KTX file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
