FAQ ▼

What is a CGM file?

A CGM (Computer Graphics Metafile) is a vector and raster graphics format used in technical docs, CAD/CAE, aerospace, and manuals. It can store lines, fills, text, and images with precise geometry. Variants include WebCGM and industry profiles (e.g., ATA GREXCHANGE). CGM is built for interchange and print fidelity rather than casual editing.

Go to the Coolutils online CGM viewer, upload your CGM, and click "View." You’ll get an instant preview in your browser—no plugins or CAD software required. Works on Windows, macOS, Linux, and mobile. Large technical drawings render with zoom and pan so you can inspect fine details without installing anything.

Can I convert CGM to PDF or images?

Yes. With Coolutils you can convert CGM to PDF, SVG, PNG, or TIFF for sharing or publishing. Upload the CGM, choose the output, set options like DPI, page size, background color, or scaling, and download the result. Converting to PDF preserves layout; SVG keeps vector data for crisp zooming on the web.

Is Coolutils CGM Viewer secure?
