DJVU files are DjVu Image files that contain compressed images in a format developed by AT&T in 1996. These files are commonly created by the DjVu File software, distributed by LizardTech. The DJVU compression method allows for larger, high-resolution color images to be compressed to a significantly smaller size, making it easier for the files to be published and distributed on the Web. In addition, this compression allows for faster download times and makes it easier for users to email the files to one another using their email client. While similar to TIFF files, DJVU files allow for a much higher compression rate.
