DjVu has been promoted as an alternative to PDF,
as it gives smaller files than PDF for most scanned
DjVu (pronounced déjà vu) is a computer file format designed primarily to store scanned images, especially those containing text and line drawings. 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 for high quality, readable images to be stored in a minimum of space, so that they can be made available on the web.
