What is an EMF file?

The Enhanced Metafile (EMF) is a 32-bit vector graphics format developed by Microsoft as a successor to the 16-bit Windows Metafile (WMF). It stores a sequence of device-independent GDI (Graphics Device Interface) drawing commands, allowing graphics to be rendered seamlessly across different output devices like printers and high-resolution displays. EMF resolves the coordinate limit issues of WMF and is commonly used within the Microsoft Office ecosystem for clipart and vector data storage.

How to open an EMF file

EMF files are natively supported by the Microsoft Windows operating system and can be opened with Windows Photo Viewer, Microsoft Paint, and Microsoft Office applications (Word, PowerPoint). On macOS, Apple Preview can convert and display EMF files. Cross-platform editing is possible using LibreOffice Draw or Inkscape, which can interpret the GDI commands and convert them to standard SVG paths.

What is a WMF file?

Windows Metafile (WMF) is a 16-bit graphics file format originally introduced in Windows 3.0 (1990) to store a sequence of Graphics Device Interface (GDI) function calls. Unlike pure bitmaps, WMFs contain instructions for drawing vector lines and circles, though they can also encapsulate raster images. The format suffers from device-dependence and lacks the color handling capabilities of its 32-bit successor, Enhanced Metafile (EMF), leading to its deprecation in modern development.

How to open a WMF file

Due to its legacy status, WMF is natively supported by the Windows Picture and Fax Viewer and Microsoft Paint. For professional editing and conversion, vector graphics software such as Adobe Illustrator, CorelDRAW, and Inkscape (using UniConvertor) is recommended. On Linux, the libwmf library enables support within the GIMP and ImageMagick suites.
