What is a CGM file?

CGM stands for Computer Graphics Metafile. It's a vector image format designed for technical illustrations, diagrams, and complex engineering drawings. The format was standardized by ISO and is mostly used in aerospace, automotive, and industrial sectors.

CGM files can contain vector shapes, raster elements, and even text instructions, making them versatile for both display and printing.

How to open CGM files

CGM files can be opened using specialized software like CorelDRAW, AutoVue, and Adobe Illustrator. Some CAD and engineering tools also support the format.

Frequently Asked Questions

Answers to common questions about converting CGM to PDF
  • Why would I convert a CGM file to PDF?
    CGM (Computer Graphics Metafile) is often used for technical illustrations, engineering drawings, and aviation documentation. Converting CGM to PDF makes these graphics much easier to open, view, print, and share on almost any device, even if the recipient doesn’t have specialized CGM software.
  • Will the PDF look the same as my original CGM graphic?
    In most cases, the PDF will closely match the original: lines, shapes, colors, and text are preserved so that diagrams remain readable. However, very complex drawings, non-standard fonts, or unusual line styles may show small differences compared to how they look in your dedicated CGM viewer.
  • Does converting CGM to PDF keep vector quality?
    PDF supports vector graphics, and many elements from CGM (curves, lines, text) are preserved as vectors. This means they stay sharp when zoomed in and print clearly. Keep in mind that the resulting PDF is meant for viewing and printing; you won’t be able to edit it as a CGM file anymore, so keep the original CGM for future edits.
  • What happens to multiple pages, layers, and annotations in a CGM file?
    Our converter focuses on producing a clear, readable PDF of what is visible in the CGM. If the file contains multiple views or pages, they may appear as separate pages in the PDF, depending on how the CGM is structured. Layers and annotations that are visible in the original graphic are typically rendered into the final document, while hidden content does not appear.
  • How can I prepare my CGM file for the best PDF conversion?
    For cleaner results, try to:
    - Use standard, widely available fonts
    - Make sure important content fits within the intended page area
    - Hide or remove elements you don’t want to show in the final document
    - Avoid extremely tiny text or overly dense details where possible
    This helps the PDF remain legible on screen and on printed pages.
  • Is it safe to convert CGM to PDF with AnyConv?
    Yes. The conversion is processed on our servers, and your files are used only to create the resulting PDF. They are never shared publicly and are automatically deleted from our servers within 1 hour after the conversion is completed.
