JLS to PRC 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.
