DjVu is a new image compression technology to solve the problem of bulky image files that are simply too large for acceptable download speeds when used on the web. For companies or individuals who deal with large numbers of image documents this not only considerably reduces the storage space required but also makes the distribution of these documents far more efficient.

DjVu typically achieves compression ratios between 5 and 10 times better than JPEG and GIF files for color documents, and 3 to 8 times better than TIFF for black and white images. Decompression is also far more efficient, with an image that would usually require 25Mb RAM to decompress only needing about 2Mb.
