About formats

WMZ is a compressed variant of the Windows Metafile (WMF) format, introduced by Microsoft with Office 2000 in 1999. A WMZ file is simply a WMF file compressed using the gzip algorithm (RFC 1952), reducing the file size for more efficient storage and embedding within Office documents, web pages, and other containers. The underlying WMF format stores vector graphics as a sequence of GDI (Graphics Device Interface) function calls — commands that draw lines, curves, polygons, text, and bitmaps — recorded in a device-independent format that can be replayed at any resolution. WMZ preserves this vector nature: when decompressed, the file produces a standard WMF that renders through the Windows GDI subsystem using the same drawing primitives as on-screen display, ensuring visual fidelity across different output devices and resolutions. WMZ files are commonly found embedded in Microsoft Office documents (Word, Excel, PowerPoint), HTML email messages generated by Outlook, and web content produced by Office's Save as Web Page feature. The format is also used for clip art and template graphics distributed with Office installations. One advantage is space efficiency: gzip compression typically reduces WMF file sizes by 60-80%, meaningful when many small graphics are embedded in a single document or web page. The format's deep integration with the Microsoft Office ecosystem is another practical strength — WMZ graphics render natively in all Office applications without additional software, and can be extracted, decompressed, and converted using tools like LibreOffice, ImageMagick, Inkscape, and standard gzip utilities.
Developer: Microsoft
Initial release: 1999
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.

Frequently Asked Questions

Why convert WMZ to EXR?

WMZ data from Microsoft Office documents and Windows clipboard becomes universally viewable once converted to EXR format.

How do I open EXR files?

You can open EXR with Nuke, Blender, Photoshop, or HDR-capable viewers. No specialized software is needed on most modern systems.

Can I convert multiple WMZ files at once?

Upload as many WMZ files as you need. Every file processes independently and delivers its own EXR output.

Can I use this converter on any operating system?

The tool is browser-based and works on Windows, macOS, Linux, ChromeOS, and mobile platforms — no OS-specific software needed.

How long does WMZ to EXR conversion take?

Conversion is fast — usually a matter of seconds. Complex or large WMZ files may need slightly more time.

Does the conversion happen on my device?

Processing happens server-side in the cloud. This keeps your computer or phone free from heavy computation work.
