日本のDTP環境では、CGMは特定の業務用ソフトウェアで利用されることが多く、一般的な画像フォーマットであるBMPへの変換は、異なるアプリケーション間での連携を円滑にする上で特に有効です。縦書き文書での図版配置の際も、BMPの互換性が役立つことがあります。
About CGM to BMP Conversion
CGM and BMP (introduced 1986) are both vector formats, but they differ in important ways. CGM is a widely used file format. BMP is an uncompressed raster format that preserves every pixel but produces very large files.
When you convert CGM to BMP, the goal is to convert between formats quickly. Converting CGM to BMP maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your CGM file is decoded and re-encoded as BMP. The conversion involves 4 steps: (1) your cgm file is uploaded and validated, (2) the file is decoded (parsed into its raw data), (3) the data is re-encoded in bmp format, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you When you need a BMP file. For the opposite direction, CocoConvert also supports BMP to CGM conversion.
How to Convert CGM to BMP
- 1
Upload .cgm file
Select your CGM file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .bmp
Set BMP as the output format. The converter uses optimal settings based on the CGM→BMP conversion profile.
- 3
Convert
The server-side engine decodes your CGM file and re-encodes it as BMP. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .bmp file. Multiple output files can be downloaded together.

Frequently Asked Questions
What is the difference between CGM and BMP?
CGM is a widely used file format. BMP is an uncompressed raster format that preserves every pixel but produces very large files.
Does CGM to BMP conversion affect quality?
Converting CGM to BMP maintains high quality with CocoConvert's optimised encoder settings.
Which format has better compression, CGM or BMP?
CGM is a common vector format. BMP uses none compression. The better choice depends on whether you prioritize file size or quality.
How long does CGM to BMP conversion take?
Most conversions finish in seconds. Larger files or complex vector content may take 10–30 seconds. CocoConvert processes files in parallel for batch jobs.
Is CGM or BMP better for long-term storage?
BMP is better for archival since it preserves all original data.
