I firmly believe working with JPEG — the universal format supported by all devices and apps—is the wisest choice. reaConverter handles these conversions flawlessly.

Working in a print studio means constantly juggling obscure file formats. I used to waste hours Googling converters or installing random software — until reaConverter became my Swiss Army knife. Install it once, and you're set forever. No internet? No problem!

FAQ

X11 to KTX2 Conversion

What are X11 files?

The X11 format is associated with the X Windows System, which is used — among others — on UNIX and Linux platforms. X11 files are bitmaps storing X Window screen caps and can come in several variations. The format is considered rare and might be difficult to open.

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.
