What is a DjVu file?
DJVU file is a graphics file format developed by AT&T Labs.
The DJVU file format was primarily designed to store different kinds of scanned documents containing a combination of text, pictures, indexed color images, and line drawings.
This format is very popular due to the high compression ratio of scanned documents. Sometimes the compression ratio is several times higher than in PDF. Due to significant compression and yet high quality of scanned materials, it is often used as the format for scanned eBooks, manuals, newspapers, etc.
Files with the DJVU extensions can be separated into three different kinds of images - background, foreground, and mask image with a higher resolution.
DjVu files can use the .DJVU or the .DJV file extension.
