What is a DjVu File?
A DjVu file mostly represents a scanned document file that may contain text, images, or figures. It is a type of file that works similarly to a PDF document. It uses lossy compression for monochrome images that enable smaller-size compression. Although lossy compression is an irreversible process, the image quality during the compression is very minimal. It also uses arithmetic coding and progressive loading, which provides lower file sizes than PDFs. It also uses text and background separation technology which creates a background layer of images and then another layer of texts and line drawings only. A combination of these technologies makes a DjVu file better handle data compression to smaller file sizes. DjVu uses the IW44 compression algorithm on an image after splitting them into three different image layers. It also uses the JB2 encoding method for more accurate and efficient compression.
