An Enhanced Metafile (EMF) is a spool file format used in printing by the Windows operating system. The EMF file format is an upgrade from the original Windows Metafile Format (WMF). Its purpose is to store both raster and vector images�which is what makes it stand out and is one of the many reasons it's favored by professionals and tech enthusiasts.
Opening EMF Files
There are many ways to open or view files with an EMF extension. The most common way is through the use of Windows-based programs since EMF is a creation of Microsoft. For example, a file with the EMF file extension can be easily opened using Microsoft Paint, Microsoft Office, and Windows Photo Gallery. Other alternatives include Adobe Illustrator and CorelDraw, both of which are excellent vector editing software. Free viewers like IrfanView can also accomplish the task.
Using EMF Files
Apart from opening, EMF files can also be converted to other formats. There are standalone converter software tools available for this, one prominent example being reaConverter. Be aware, however, that when converting to formats other than vector-based formats, quality loss may occur. If you are using EMF files for graphical work in a professional setup, it's recommended to keep them in their original format or convert them to other vector formats like SVG.
Using EMF Files for Printing
EMF files are also used internally by the Windows operating system for printing. When a print job is sent to the printer, the data is held in the printer spool (queue) as an EMF file until the printer is ready. This helps in managing and scheduling pending print jobs. As such, it is not typically expected for average users to be handling EMF files in this scenario.
EMF File Important Information
Although the EMF file format can be highly beneficial, it is essential to understand that not all applications can open or edit EMF files, which limits its versatility. Keep in mind that quality can degrade considerably if you convert an EMF file into a non-vector file format. Lastly, always ensure the source of your EMF files is secure, as harmful code can be embedded in the files. Given their close association with Windows OS, such files can pose a potential threat if not handled carefully.
