A JLS file is an image saved in the JPEG-LS file format. It contains a lossy or lossless compressed image. JLS files are typically created by medical imaging devices and digital cameras.

In 1999, the Joint Photographic Experts Group (JPEG) released an addition to the original JPEG standard, describing a compression format that allowed programs to save images both losslessly and near-losslessly. That compression format and its associated file format were named JPEG-LS. Notably, JPEG-LS compression allows users to control the maximum amount of data that is lost when a program compresses their image, which is what makes the lossy version of the format "near-lossless."
While JPEG-LS files are saved using the .jls extension, other file formats, such as .JPX and .SPIFF, also sometimes use JPEG-LS compression. JPEG-LS and JPEG, however, are different file formats, so programs that can open a .JPEG or .JPG often cannot open JLS files.
