What is CGM?

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

What is AVIF?

AVIF (AV1 Image File Format) is a new image format based on the AV1 video codec. It provides outstanding image quality and compression efficiency.

When Should You Use CGM vs AVIF?

Use CGM When...

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

Use AVIF When...

Reach for AVIF when your priority is modern web, next-generation web applications — its efficient compression makes sharing fast and storage minimal.

CGM vs AVIF: Key Differences

  • •CGM and AVIF diverge on compression: lossless compression for the source, lossy compression for the target.
  • •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
  • •How transparency is handled: AVIF does not support alpha channels — transparent areas in the source will become opaque.
  • •File sizes: CGM files typically range Compact for vector drawings and AVIF files 40-50% smaller than JPEG/PNG.
  • •Primary audience: CGM is built for technical illustrations, engineering diagrams scenarios, while AVIF focuses on modern web, next-generation web applications — pick the format that matches your output requirement.

Advantages of CGM

  • ✓CGM uses lossless compression tailored for Technical illustrations, engineering diagrams.
  • ✓CGM is supported natively on virtually every device, browser, and operating system.
  • ✓CGM files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓CGM integrates seamlessly with all major creative tools and workflows.

Advantages of AVIF

  • ✓AVIF uses lossy compression tailored for Modern web, next-generation web applications.
  • ✓AVIF is supported natively on virtually every device, browser, and operating system.

Troubleshooting CGM to AVIF Conversion

  • !Converting CGM to AVIF gives blurry output → increase the quality setting before conversion
  • !Colors look different in AVIF than CGM → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → AVIF uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in CGM turned white in AVIF → AVIF may not support transparency
