TCR to JBG conversion is the process of transforming an ebook or mobile-optimized TCR (TIFF-based Compressed Raster) file into the JBG (JPEG-Bi-level Group) format, producing a JBG image or multipage bitonal image suitable for archival or printing workflows. This conversion repackages the raster pages, optionally adjusting compression and resolution settings to balance file size and readable detail for scanned text and illustrations.

TCR files are less commonly supported and often larger in size, while JBG offers superior compression and broader compatibility. Although both are image formats, JBG is favored for efficient storage and faster loading times in modern applications.
Keep individual source pages under 5–10 MB when possible; large high-resolution TCR pages increase memory and processing time.
To preserve text clarity, convert at 200–300 DPI and use conservative binarization (thresholding) rather than aggressive lossy compression.
For large ebook batches, use batch conversion with consistent DPI and compression presets to ensure uniform output.
TCR often contains color or grayscale scans; JBG is bi-level—expect conversion artifacts on photos and fine gradients and consider pre-processing (deskew, despeckle) first.
