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.
