It allows distribution of scanned documents, photographs and high definition images on the internet. There are an entire set of DjVU viewers, browser add-ons, and devices for execution of binary codes which exists on both windows and Mac devices.
Technical details In early 1990s and 2000s, the AT&T developed DjVU by Yann LeCun, Leon Bottou, Patrick Haffner, and Paul G. Howard. It is viewed as superior compared to PDF due to its ability to easily convert large amounts of text to DjVU, its small-sized files and people can use it freely.
