DjVu

DjVu is a digital file format designed for efficiently storing and sharing scanned documents, especially those with high-quality images, such as books, magazines, or historical texts. It uses advanced compression techniques to reduce file size while preserving clarity, making documents quicker to download and easier to view without sacrificing detail. DjVu separates images and text into layers, enabling clear text-to-background contrast and smooth zooming. This format is particularly useful for scanned materials that contain complex visuals or detailed images, offering a balance between high image quality and small file size for improved accessibility and storage.
