What is CGM?

Computer Graphics Metafile (CGM) is a vector and raster graphics format for technical illustrations and engineering diagrams.

What is QOI?

QOI (Quite OK Image) is a lossless image format designed for simplicity and performance. It offers fast encoding and decoding with compression ratios comparable to PNG, making it ideal for game development and real-time applications.

When Should You Use CGM vs QOI?

Use CGM When...

Reach for CGM when your priority is technical illustrations, engineering diagrams — its uncompromising quality ensures every detail is preserved.

Use QOI When...

Reach for QOI when your priority is game development, pixel art, embedded systems, quick texture loading — its uncompromising quality ensures every detail is preserved.

CGM vs QOI: Key Differences

•CGM and QOI diverge on compression: lossless compression for the source, lossless compression for the target.
•Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
•How transparency is handled: QOI supports transparency, so alpha information is preserved during conversion.
•Storage footprint: Compact for vector drawings for CGM vs Similar to PNG, typically 20-30% smaller than uncompressed data for QOI.
•Use case fit: CGM targets technical illustrations, engineering diagrams and QOI targets game development, pixel art, embedded systems, quick texture loading — your choice depends on which workflow stage you are serving.

Advantages of CGM

✓The lossless nature of CGM means file sizes stay reasonable while handling Technical illustrations, engineering diagrams efficiently.
✓From mobile devices to enterprise servers, CGM is recognized and supported everywhere.
✓The trade-off for CGM's perfection is larger files — but for archival work, it is worth every megabyte.
✓CGM is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of QOI

✓QOI compresses data using lossless methods, keeping file sizes manageable for Game development, pixel art, embedded systems, quick texture loading.
✓Industry-wide support means QOI files open anywhere — from legacy systems to the latest devices.
✓Lossless quality makes QOI the gold standard for archival and master copies.
✓From professional software to open-source alternatives, QOI works out of the box.

Best Practices for CGM to QOI Conversion

→When converting CGM to QOI, check whether QOI supports transparency — if not, your transparent areas will be filled with a solid color
→Use QOI for maximum quality archival and CGM for lossless workflows
→Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
→Maintain original aspect ratio to avoid distortion during conversion
→Always keep a backup of your original files before converting
→Choose the appropriate quality settings for your specific use case

Troubleshooting CGM to QOI Conversion

!QOI shows visible compression artifacts → lower the compression level or switch to a lossless variant
!The converted QOI image looks washed out → the source CGM likely uses a wider color space than QOI supports
!QOI file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
!Text in the converted QOI looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
