FAQ
ISS to KTX2 Conversion
What are ISS files?
The ISS image format is considered rare and obsolete, and such files can only be opened using a limited number of image viewers. ISS files most likely contain bitmap images that were created or edited a long time ago. In case you have received such a file or found one on an old hard-drive, the best way to access its content is conversion to a better known format, such as JPEG or PNG.
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.
