Convert Computer graphics metafiles (CGM) online for free
The converter easily converts your CGM Graphics files to various formats - free and online. No Siemens NX or other Vector Image software needed.
To convert other file formats to the "Technical Illustration File" file type, you need software like Siemens NX or a similar tool.
A .CGM (Computer Graphics Metafile) is an ISO/IEC 8632 standard vector graphics format. It is primarily used in aerospace, defense, and automotive industries to store 2D technical illustrations, CAD drawings, and interactive electronic technical manuals (IETMs). You can open and edit these files using enterprise engineering software like Siemens NX, Dassault Systèmes CATIA, or CorelDRAW.
The main disadvantage of the .CGM format is its lack of consumer accessibility. Because it was defined in the 1980s and relies heavily on specialized industrial software, .CGM files are notoriously difficult to open on standard computers. Modern web browsers and default image viewers do not support this format natively, which creates friction when sharing technical manuals or diagrams outside of an engineering department.
To make a .CGM file usable on modern devices, you must convert it. For web display, convert to SVG, which retains vector scalability and is natively supported by all browsers. For sharing, archiving, and printing, convert to PDF. If you need to edit the drawing in a different CAD application, converting to DXF is the best option. Drag and drop your file here to analyze and convert it - free, online, and without installing software.
Use Convert.Guru to open and convert your CGM file.
Users also converted CMG, GCM, REP, HPG, PNG, CATDRAWING, PDF, BAK, DWF, CTB, DXF, SVG and JPG files.
If you want to convert CGM file to DXF, DWG, AI, CDR or WMF, you can use Siemens NX or similar software from the "Technical Vector Graphics Storage" category. In the File menu, look for Save As… or Export….
To convert AFPUB, EPS, FIG, VSD, SKETCH, VDX, AFPHOTO, PDF, AFDESIGN, SVG, VSDX or AI files to CGM, try Siemens NX or another comparable tool in the "Technical Vector Graphics Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CGM converter.
