DjVu uses technologies such as image layer separation of text and background images, progressive loading, lossy compression, and arithmetic coding for bitonal images. Due to advanced compression algorithms, DjVu is ideal for high-quality, readable images to be kept in a minimum of space. A huge number of scanned books, magazines, manuals, photo books, etc. are stored in DjVu format.
