JLS to DDS 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 DDS files?

DDS (DirectDraw Surface) is an image file format that usually contains texture data, cubic environment maps or other type of data compressed using the S3TC (S3 Texture Compression) algorithm. The DDS format was first associated with Microsoft's DirectX 7.0 and later on with DirectDraw, a tool for accelerating the rendering of graphics in various applications.
