JXL to SIXEL
File Converter

JXL stands for JPEG XL, a next-generation image coding standard developed by the Joint Photographic Experts Group (JPEG). JPEG XL is designed to provide efficient compression for both lossless and lossy image storage, offering high image quality at lower file sizes compared to previous standards. It supports a wide range of features including high dynamic range, wide color gamut, and progressive decoding, making it suitable for use in various applications from web graphics to professional photography. Despite its advantages, as a newer standard, JPEG XL may not yet have widespread support across all platforms and software.

SIXEL is a bitmap graphics format that uses six pixels per character cell to represent images, primarily developed for DEC (Digital Equipment Corporation) terminals in the 1980s. It allows for the display of images directly in terminal emulators that support the SIXEL standard, making it possible to visualize graphics in command-line environments without relying on external graphics programs.
