JBIG2 to KTX2 Conversion
What are JBIG2 files?
JBIG2 (.jbig2) is a bi-level image compression standard (ITU-T T.88) optimized for scanned text and documents. It encodes repeated symbols through a shared dictionary and uses arithmetic coding to minimize data size. Supporting both lossless and lossy modes, JBIG2 achieves far higher compression than TIFF G4, especially on text-rich pages. Commonly embedded in PDF and DjVu files, it is ideal for compact monochrome document storage and transmission.
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.
