DjVu (pronounced like French déjà vu) is a open computer file format. It is made mostly to store scanned documents. It is especially used for things with a mix of words, line drawings, and photographs inside. DjVu has been sold as an alternative[1] to PDF, as it gives smaller files than PDF for most scanned documents. The DjVu developers report[2] that color magazine pages make smaller to 40–70 kB. Black and white technical papers make it smaller to 15–40 kB. Old manuscripts make smaller to around 100 kB; a satisfactory JPEG image usually needs 500 kB. Like PDF, DjVu can have a OCR text layer. This makes it easy to cut and paste, and search for text.
