About formats

JPEG is one of the most widely used image formats in computing, standardized by the Joint Photographic Experts Group and published as ISO/IEC 10918-1 in September 1992. The .jpeg extension is functionally identical to .jpg — both contain the same JFIF or Exif-wrapped JPEG compressed image data. The format applies lossy compression using the discrete cosine transform (DCT): images are divided into 8x8 pixel blocks, transformed into frequency coefficients, quantized to discard visually less significant information, and entropy-coded for storage. The quality-to-size tradeoff is user-selectable, with typical settings producing files 10-20 times smaller than uncompressed originals at visually acceptable quality. JPEG supports 8-bit grayscale and 24-bit color, with Exif metadata carrying camera settings, GPS coordinates, timestamps, and thumbnails. One advantage is absolute universality — JPEG is readable by every image viewer, web browser, operating system, camera, phone, and printer manufactured in the past three decades, making it the safest format for sharing photographic images with any recipient. The efficient compression of continuous-tone photographic content is another core strength: JPEG consistently produces compact files from camera sensors and real-world scenes where subtle color gradients dominate. While newer formats like WebP and AVIF achieve better compression ratios, JPEG's installed base is so vast that it remains the default output of digital cameras and the most common image format on the web.

DjVu (pronounced "deja vu") is a document format developed at AT&T Labs by Yann LeCun, Leon Bottou, Patrick Haffner, and Paul Howard, first released in 1996. The format was specifically designed for storing scanned documents and images at very high compression ratios while maintaining visual quality suitable for on-screen reading. DjVu achieves this through a layered approach: the document image is separated into a foreground layer (text and line art at full resolution), a background layer (photographs and textures at reduced resolution), and a mask layer that determines which layer is visible at each pixel. This separation, combined with purpose-built compression algorithms for each layer type, typically produces files 5-10 times smaller than equivalent JPEG or PDF scans. One advantage is exceptional compression on scanned pages — a 300 DPI color scan that might occupy 25 MB as TIFF or 500 KB as JPEG typically compresses to 40-80 KB in DjVu while preserving legible text. The progressive rendering model is another strength: DjVu files stream efficiently over networks, displaying a readable low-resolution version almost immediately while progressively refining to full quality. The format supports multi-page documents, embedded text layers for searchability, hyperlinks, annotations, and a shared dictionary mechanism that further compresses collections of similar pages. DjVu is widely used by libraries and archives for digitized historical documents and manuscripts.

Frequently Asked Questions

Why convert JPEG to DJVU?

DjVu excels at compressing scanned documents and images with text. Converting JPEG to DjVu produces highly compact documents ideal for archiving.

Which apps support DJVU?

Use Okular, DjVu Viewer, Sumatra PDF, WinDjView to view and edit DJVU. The format is well-supported across popular software packages.

How long does JPEG to DJVU conversion take?

Most conversions finish within seconds. Processing time depends on image size and server load, but JPEG to DJVU is typically very quick.

Is batch JPEG to DJVU conversion supported?

Absolutely. Queue up multiple JPEG images in a single session and convert them all to DJVU simultaneously — no need to process one at a time.

Will my image lose quality?

Image fidelity is maintained as well as DJVU allows. The converter optimizes the transformation to preserve maximum visual quality during processing.
