DjVu (/ˌdeɪʒɑːˈvuː/DAY-zhah-VOO, like French "déjà vu"[2]) is a computer file format designed primarily to store scanned documents, especially those containing a combination of text, line drawings, indexed color images, and photographs. It uses technologies such as image layer separation of text and background/images, progressive loading, arithmetic coding, and lossy compression for bitonal (monochrome) images. This allows high-quality, readable images to be stored in a minimum of space, so that they can be made available on the web.
DjVu has been promoted as providing smaller files than PDF for most scanned documents.[3] The DjVu developers report that color magazine pages compress to 40–70 kB, black-and-white technical papers compress to 15–40 kB, and ancient manuscripts compress to around 100 kB; a satisfactory JPEG image typically requires 500 kB.[4] Like PDF, DjVu can contain an OCR text layer, making it easy to perform copy and paste and text search operations.
Free creators, manipulators, converters, web browser plug-ins, and desktop viewers are available.[2] DjVu is supported by a number of multi-format document viewers and e-book reader software on Linux (Okular, Evince, Zathura), Windows (Okular, SumatraPDF), and Android (Document Viewer,[5] FBReader, EBookDroid, PocketBook).
