CGM File: The Ultimate Guide to CGM Files

CGM stands for Computer Graphics Metafile, which is an image format created in 1986. They are a type of text and binary file that contains a textual translation of the graphic information. The file format is used to store vector graphics and text.

The World Wide Web Consortium, a group focused on developing standards for the internet age, has developed WebCGM. This is a specification that defines how CGM files should be formatted when transmitted over the web.

Despite being a more established file format with some utility in technical illustration, CGM has largely been replaced by SVG and DXF in the professional design space.

What is a CGM file format?

The CGM file format is used to store vector graphics and text and is most often used for the computer-aided design, draft, and print industry. CGM is a standard for exchanging graphics data that's independent of any particular application, system, or platform. It provides the means to represent 2D graphical information in computer-based formats easily transmittable across different devices like cell phones and tablets without losing quality.

Are CGM files dangerous?

As with any file you open on your computer, it is important to keep in mind that sophisticated malware designers are always looking for ways to exploit security loopholes to access your personal information. CGM files, like other graphics formats such as BMP and JPG, can be dangerous if you download the file from an unverified location or open it after saving it by mistake. These files can allow a system to retrieve sensitive data which might lead to malware infection and loss of privacy.

If you often download media from unverified sources, you should always use a malware and virus scanner to scan the files before opening them. In this way, you can help avoid trouble and ensure your files are safe.
