DjVu Compressed Document

DjVu is a compressed document format developed at AT&T Labs in the mid-1990s, designed to store high-resolution scanned documents at dramatically smaller file sizes than PDF or TIFF. It achieves this by separating a page into distinct layers — background, foreground, and text — and compressing each layer with different algorithms. DjVu became popular for digitizing books and academic journals, particularly in Eastern Europe and for public domain archives like the Internet Archive, though it lacks PDF's broad viewer support.
