What is an .JB2 file?
.JB2 file extension is created by Joint Bi-level Image Group. .JB2 has been classified as Raster Image Files. The format of .JB2 file is Binary.
.JB2 is JBIG2 Image
Bitonal image created in the Joint Bi-level Image Group 2 (JBIG2) format; stores 1-bit black and white pixels in lossy or lossless format; supports greater compression ratios than the competing CCITT Fax Group 4 compression algorithm.
JB2 are segmented into three types of regions: text, halftone images, and generic regions. This allows the JBIG2 algorithm to optimize compression for the different areas of the image.
Because of their high compression ratios, JBIG2 images are commonly used to store binary images for transmission via fax. JBIG2 files replaced the previous JBIG specification (.JBIG files).
