JLS to DCX Conversion: FAQ

What are JLS files?

JPEG-LS .jls is a lossless (and optionally near-lossless) image-compression standard that uses the lightweight LOCO-I predictor plus context-adaptive run-length coding to capture local pixel correlations with very low complexity. It typically delivers higher compression ratios than baseline JPEG while decoding quickly and requiring little memory, making it well-suited for medical, scientific, and embedded imaging where exact pixel fidelity and minimal latency are vital.

What are DCX files?

DCX files are multi-page images consisting of raster graphics, usually used to create fax files and functioning as a header that introduces a series of ensuing PCX files. DCX is a bitmap format and was initially developed together with the PCX format by Zsoft Corp. and was associated with PC Paintbrush. This graphics editing software was popular in the late 1980s on computers using the MS-DOS operating system, and later on it was adapted for Windows too.
