What is a DJVU file?
DjVu is a raster image file format developed by researchers at AT&T Labs (including Yann LeCun) specifically for storing high-resolution scanned documents. It employs a content-specific compression algorithm that separates images into three layers: background (paper texture), foreground (text/line art), and a bi-level mask (JB2 compression), enabling high compression ratios superior to PDF or TIFF. The format utilizes arithmetic coding (ZM-coder) and wavelet-based compression (IW44) to deliver legible text rendering at low bitrates.
How to open a DJVU file
Most operating systems do not include native kernel support for DjVu rendering. To open these files, users require specialized viewers such as DjView4, WinDjView (Windows), or MacDjView (macOS). Multi-format image viewers like IrfanView (with plugins) and XnView also support the format. For browser-based access, specific plugin implementations or conversion to PDF are often required as modern browsers do not render DjVu natively.

What is a PDF file?
The Portable Document Format (PDF) is a comprehensive file format, standardized as ISO 32000, designed to present documents consistently independent of application software, hardware, and operating systems. It encapsulates a complete description of a fixed-layout 2D document, including text, fonts, vector graphics, and raster images, based on the PostScript language. Advanced implementations support interactive form fields, JavaScript scripting, 3D objects (U3D/PRC), and various encryption standards.
How to open a PDF file
PDF viewing is natively supported by all major modern web browsers (Chrome, Edge, Firefox, Safari) and most operating systems via built-in previewers. For advanced manipulation, form filling, or pre-press validation, dedicated software such as Adobe Acrobat DC, Foxit Reader, or open-source tools like Ghostscript and Poppler is required.
