Convert CUBE to JBG

A CUBE file (short for Color Lookup Utility Table) is a 3D Lookup Table used in Luminar software for color grading and photo editing. It allows photographers to remap colors and adjust tones efficiently. Introduced in Luminar 2018, CUBE files enable users to apply complex color adjustments with a single click, enhancing workflow and creative flexibility. The format is also compatible with other editing software like DaVinci Resolve.

The JBG file extension stands for Joint Bi-level Image Group, a format developed for efficient lossless compression of binary images, primarily used in fax transmissions. Introduced by the Joint Bi-level Image Experts Group, JBG files store 1-bit raster images and offer superior compression compared to older standards like CCITT Group 3 and 4. Although initially popular for fax machines, the format has largely been superseded by JBIG2, which provides even better compression.
