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/A file?
PDF/A is an ISO-standardized (ISO 19005) variant of the PDF format designed specifically for long-term digital archiving. It embeds all fonts, color profiles, and metadata directly inside the file and prohibits external dependencies, encryption, and JavaScript, ensuring the document will render identically decades from now regardless of which software or fonts are available on the viewing system. It's widely required for legal, government, and institutional record-keeping.
How to open a PDF/A file
PDF/A files open in any standard PDF viewer, including Adobe Acrobat Reader, Apple Preview, and built-in browser PDF viewers, since the format is fully backward-compatible with regular PDF readers. Dedicated archival software such as Adobe Acrobat Pro can also validate that a file meets PDF/A compliance.
