FAQ

MIM to KTX2 Conversion

What are MIM files?

MIM (Multi-Purpose Internet Mail Message) is a generic format used by some email programs to encode sent or received data. A MIM file can refer to the content of the email message or to its attachment. In both cases, opening such a file outside the email program which created it might be difficult. One handy option for handling MIM files is converting them to more widely available image format, such as JPEG.

What are KTX2 files?

KTX2 (Khronos Texture 2.0) is a container file format for GPU-ready texture data, published by the Khronos Group as the successor to the original KTX format. A single file can hold 1D, 2D, 3D, cubemap and array textures together with their full mipmap chains, stored in the memory layout expected by graphics APIs such as Vulkan, OpenGL and OpenGL ES, so the contents can be uploaded to the video card with little or no additional processing. Besides plain block-compressed data, KTX2 supports supercompression: Basis Universal (ETC1S and UASTC) allows one file to be transcoded at load time into the format the target device actually needs, while Zstandard and ZLIB simply reduce file size. The format is the texture payload used by the glTF KHR_texture_basisu extension, which makes it common in 3D assets for the web, game engines and AR applications.
