The JBF file format is associated with PaintShop Pro, a popular image editing software developed by Corel. It is essentially a cache file that stores thumbnail images of the graphics and photographs that a user has browsed using the software's built-in browser feature. This caching mechanism allows for quicker loading and browsing of images within the application by storing a small, quick-to-load version of each image. JBF files are automatically generated and updated by the software as users browse through their image collections.
Image stored in the JPEG XR format, which was originally developed by Microsoft for Windows Media software; supports deep color images with 48-bit RGB; used for high-resolution professional image editing; also supports lossless and lossy compression.
