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
SXW is the word processing document format used by StarOffice 6.0 and OpenOffice.org 1.0, developed by Sun Microsystems and released in 2002. The format was one of the first mainstream office document formats to adopt an XML-based architecture, packaging document content, styles, metadata, and embedded media in a ZIP archive — a structural approach that directly influenced the later OpenDocument Format (ODF). The content.xml file describes the document body using XML elements for paragraphs, headings, lists, tables, footnotes, and inline formatting, while styles.xml defines the styling rules and meta.xml carries document properties. SXW represented a significant milestone in open-source office software, demonstrating that a non-proprietary XML format could handle the full range of word processing features including change tracking, indexes, cross-references, and complex page layouts. One advantage was transparency and openness — the XML structure made document content inspectable, transformable, and processable using standard tools, a sharp contrast to the opaque binary formats dominant at the time. The format's role as a technological precursor to the ODF standard is another historical significance: the OASIS OpenDocument Technical Committee used the OpenOffice.org XML format (including SXW) as the starting point for developing ODF 1.0. While SXW was superseded by ODT with OpenOffice.org 2.0 in 2005, existing SXW documents can be opened by LibreOffice, Apache OpenOffice, and document conversion tools.

Frequently Asked Questions

Why convert EXR to SXW?

Portfolio and client review workflows need standard formats — EXR to SXW ensures your HDR renders reach every stakeholder.

What programs open SXW files?

LibreOffice Writer, Apache OpenOffice, and legacy StarOffice/OpenOffice.org open SXW documents

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.

Can I batch convert multiple EXR files to SXW?

Upload several EXR files at once. Each one converts to SXW independently — download them individually or together when all are done.

Can I convert EXR to SXW without paying?

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

Will the converted SXW keep the original resolution?

Yes — the default conversion preserves the original pixel dimensions
