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.

How do I open a CGM file online?

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?

Yes. Files are transferred via HTTPS and processed only for your session; uploads are automatically deleted within 24 hours. We never share your documents with third parties. For highly sensitive content, Coolutils also offers offline converters so you can process CGM files entirely on your own machines.

Is the online CGM viewer free?

Yes, completely free with no hidden costs, subscriptions, or file limits. View unlimited CGM files without registration or payment. All viewing features are available at no charge.
