About formats

EXR is a high-dynamic-range raster image format developed by Industrial Light & Magic (ILM) internally since 1999 and publicly released as open-source software in January 2003. OpenEXR was created to meet the demanding requirements of feature film visual effects compositing, where scenes routinely contain extreme brightness ranges — from deep shadows to specular highlights on water, metal, or light sources — that exceed the precision of 8-bit or 16-bit integer formats. EXR stores pixel data in 16-bit floating-point (half) or 32-bit floating-point per channel, providing over 30 stops of dynamic range with smooth precision across the entire luminance spectrum. The format supports an arbitrary number of channels (not just RGBA), tiled and scanline storage, multiple compression methods (lossless ZIP, lossy B44 and DWAA/DWAB for preview quality), multi-part files containing multiple views or layers, and deep pixel data where each pixel stores multiple depth-sorted samples for volumetric effects. One advantage is compositing fidelity: the floating-point precision means that color grading, exposure adjustments, lighting changes, and multi-layer compositing operations produce mathematically correct results without the banding, clipping, or quantization artifacts inherent in integer formats. EXR's adoption as the VFX industry standard is another core strength — it is the default interchange format for Foundry Nuke, Autodesk Flame, Blackmagic Fusion, Adobe After Effects, and every major 3D renderer, and its open-source C++ library is embedded in hundreds of production tools.
Initial release: January 2003
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 EXR to DJVU?

Tonemapping EXR data into DJVU preserves the visual intent while making images accessible outside the VFX pipeline.

What programs open DJVU files?

DjVu Viewer, WinDjView, MacDjView, Sumatra PDF, Okular, and the DjVuLibre open-source toolkit

Can I convert EXR to DJVU without paying?

Yes — basic EXR to DJVU conversion is available at no cost. Paid tiers unlock batch mode, bigger uploads, and faster processing.

Are colors preserved in the EXR to DJVU conversion?

EXR stores extended dynamic range data. Converting to DJVU maps that range into the displayable gamut while retaining visual accuracy.

Is my EXR file safe during conversion?

Uploaded files are processed securely and deleted after conversion. Downloaded results are removed from servers within 24 hours.

Does the conversion preserve transparency?

DJVU does not support transparency natively. Alpha channel data from EXR will be flattened against a solid background during conversion.
