Why convert CGM to GIF?
CGM (Computer Graphics Metafile) is the ISO vector graphics standard used for technical illustrations in aerospace, defence and engineering manuals. LibreOffice draws the metafile's lines, filled shapes and text onto a page, which is rendered at 144 dpi so the illustration stays crisp.
GIF stores the image with an optimised palette of up to 256 colours, which suits text, diagrams and flat colour.

Frequently Asked Questions
How do I convert CGM to GIF?
Drop your CGM file above and press Convert. Our servers open the CGM with LibreOffice, export it as a PDF and render each page of that PDF as the image you chose. The result is saved as a GIF image, ready to download.
Do the text labels in a CGM illustration show up in the GIF?
Yes. LibreOffice imports the metafile's text along with its lines and filled shapes, so callouts and labels are drawn in place.
Are the fills and colours of a CGM illustration kept in the GIF?
LibreOffice draws the filled areas, line colours and text as the metafile defines them, and the page is rendered at 144 dpi in full colour.
What happens when a CGM file fills several GIF pages?
Each page is rendered at 144 dpi and saved as its own GIF image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one GIF file.
How are colours handled in the CGM to GIF image?
GIF uses a palette of up to 256 colours. The converter builds an optimised palette from the rendered image, which keeps text, lines and solid colours clean.
