About formats

RGB is a raw (headerless) image format that stores pixel data as a flat sequence of red, green, and blue sample values with no container structure, compression, or metadata. Each pixel is represented by three consecutive bytes (in 8-bit mode) — one for red intensity, one for green, and one for blue — written in scanline order from the top-left corner of the image to the bottom-right. Because there is no header, the image dimensions and bit depth must be specified externally when reading the file. The format supports multiple bit depths: 8-bit (0-255 per channel), 16-bit (0-65535 per channel), and floating-point variants, with 8-bit being the most common. The RGB color model itself reflects how display hardware produces color — by mixing red, green, and blue light at varying intensities — and raw RGB files represent this model in its most direct digital form. With 8-bit channels, three bytes per pixel yield a 24-bit color palette capable of representing 16,777,216 distinct colors. One advantage is zero-overhead processing: without headers or compression to parse, raw RGB data can be memory-mapped, fed directly into GPU textures, or piped between processing stages with minimal latency — valuable in real-time imaging, scientific instrumentation, and computer vision pipelines where every millisecond matters. The format's universal simplicity provides another practical strength — any programming language can read or write raw pixel data with just basic file I/O, making it a reliable interchange format between custom software that may not share support for structured image containers. Raw RGB files are handled by ImageMagick, FFmpeg, and various scientific and graphics tools.
Initial release: 1990
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 RGB to DJVU?

Raw RGB data lacks compression and file headers, making it unviewable in standard tools. DJVU provides a structured, widely supported alternative.

What programs open DJVU files?

DJVU files can be opened in DjVu viewers (WinDjView, Evince), web browser plugins, and document readers with DjVu support.

Does RGB to DJVU conversion cost anything?

Basic conversions are completely free. If you need higher volume or larger data support, Convertio offers affordable premium options.

How does Convertio protect my uploaded data?

Your RGB data is encrypted during transfer and deleted after processing. Converted DJVU outputs are purged from servers within 24 hours.

Does converting RGB to DJVU lose quality?

The conversion preserves the visual content of your RGB data accurately. Any differences depend on DJVU's format characteristics like compression type.

Can I convert RGB to DJVU on my phone?

Yes — the converter works in mobile browsers on both Android and iOS. No app installation needed, just open the page and upload.
