How to convert CGM to SVG
- Add your .CGM file - drop it in the box above or click to browse.
- Convert it to .SVG in a few seconds.
- Download your new .SVG file.
What to expect
- Embedded raster cell arrays in a
.cgmfile export as<image>elements in SVG - they remain raster and will not scale crisply. - WebCGM files used in interactive technical manuals carry hotspots and hyperlinks that SVG cannot replicate; geometry converts but interactive metadata is dropped.
- CGM is common in aerospace and defense documentation; avoid uploading sensitive or export-controlled files to online services - use UniConvertor or CorelDRAW locally instead.
Frequently asked questions
Is CGM to SVG a lossless conversion?
For vector geometry - lines, polygons, arcs, and text - yes. Embedded raster cells stay raster, and WebCGM interactive metadata is not carried over.
Why does Inkscape not open my .cgm file?
Inkscape has no built-in CGM reader. Convert the file to
.svg first using our converter or UniConvertor, then open it in Inkscape.The online converter returned a blank SVG. Why?
The tool likely misidentified the CGM encoding (Binary vs. Clear-Text), or the file uses a specialized profile like CALS or ATA with elements the converter does not support. Try UniConvertor locally for better results.
Can I convert CGM to SVG for free?
Yes - our converter above is free, and UniConvertor is free and open-source for Linux and macOS.
