What is MIME type "image/wmf"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

image/wmf is a MIME type for Windows Metafile images. It defines a file format that stores vector graphics along with embedded bitmap data. These files hold drawing commands such as lines, shapes, and text, allowing images to scale without loss of quality.

This format is native to Windows environments. It is used in graphics-intensive applications and legacy office software. Files like WMF, WMZ, and APM typically employ this MIME type.

• Scalable Graphics: Works well for images that need to resize cleanly.
• Legacy Support: Remains important for older Windows applications and clip art libraries.
• Efficient Data Storage: Encodes drawing instructions rather than storing every pixel.

This MIME type helps operating systems and applications identify and process Windows Metafile content. For more detailed file usage information, see the references on external sites like Filext.
