What is it?
WMF (Windows Metafile) is a graphics file format introduced by Microsoft for Microsoft Windows. It is a metafile, meaning it stores an image as a sequence of drawing instructions rather than a grid of pixels, and it can hold both vector graphics and embedded bitmap data.
A WMF file records a list of Graphics Device Interface (GDI) function calls, the same commands Windows uses to draw to a screen or printer. To display a WMF, an application replays these stored records through GDI. The original format was not device-independent, though optional placeable headers were later added to improve portability.
Technical Specifications
Pros & Cons
Advantages
As a command list rather than a pixel grid, WMF can describe lines, curves and text compactly and scale them without the pixelation of raster formats.
Because records map directly to GDI calls, Windows and most Windows applications can render WMF without external libraries.
A single WMF can combine vector primitives with embedded bitmap images and limited text, making it flexible for clip art and documents.
Microsoft published the format as the open MS-WMF specification, allowing third-party tools to read and write it accurately.
Disadvantages
The format is tied to the 16-bit Windows GDI model, so it is poorly supported outside Windows and largely superseded by EMF and SVG.
The original WMF lacked a reliable coordinate header, so images could render at unpredictable sizes across devices.
WMF's ability to embed executable-style records has historically been exploited, leading many platforms to restrict or sanitize it.
When to Use It
WMF is most often encountered in legacy Windows documents and clip art collections.
Библиотеки клипартов
Microsoft Office and older clip art galleries distributed scalable artwork as WMF files for insertion into documents.
Графика офисных документов
Drawings and diagrams pasted between older Windows applications were frequently stored on the clipboard and in files as WMF.

WMF was used to spool simple vector graphics to Windows printers via GDI before richer formats became standard.
How to open a WMF file
WMF files, or Windows Metafile Format files, can be opened and edited using a variety of software tools that cater to different user needs. Professional graphic design applications offer advanced editing features, while free and open-source tools provide basic functionality for casual users. Browser-based solutions can be convenient for quick viewing, and built-in options in operating systems allow for immediate access without additional installations.
When choosing software for WMF, important factors include feature fidelity for accurate rendering, the balance between editing and viewing capabilities, and the cost model that fits the user's budget. Platform compatibility is also crucial, as some applications are limited to specific operating systems. Additionally, understanding when to convert WMF files to other formats can help streamline workflows, especially if the end goal is compatibility with other software.
