For those of you that are unfamiliar with the DjVU format, it is a format that is commonly used for scanned images. It is usually advertised as being an alternative to the PDF file format, especially for people who want to scan documents and keep the file size of the electronic document as small as possible.
So there might be times when you do encounter the format, especially when reading eBooks. If you are reading DjVU files on your mobile device regularly, here are some of the best DjVU viewers on the market for both iOS and Android users.
