 This extension adds the ability to specify textures using KTX v2 images with (ASTC compression)[https://github.com/ARM-software/astc-encoder/blob/main/Docs/FormatOverview.md]. An implementation of this extension can use such images as an alternative to the PNG or JPEG images available in glTF 2.0 for more efficient asset transmission, reducing GPU memory footprint, higher texture throughput and faster execution.
 
-When this extension is used, it's allowed to use value `image/astc` for the `mimeType` property of images that are referenced by the `source` property of `KHR_texture_astc` texture extension object.
+When this extension is used, it's allowed to use value `image/ktx2` for the `mimeType` property of images that are referenced by the `source` property of `KHR_texture_astc` texture extension object.
 
 At runtime, engines can directly use the ktx images unlike EXT_texture_basisu which requires doing transcoding to other compressed formats. This also means you get support for all ASTC block formats and quality presets.
