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 PGM vs AVIF?

Use PGM When...

Reach for PGM when your priority is grayscale image processing, scientific data — 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.

PGM vs AVIF: Key Differences

  • •The core technical difference: PGM relies on lossless compression whereas AVIF uses lossy compression.
  • •Converting from PGM to AVIF changes compression type: lossy source becomes smaller but with some quality tradeoff.
  • •Transparency: Supports full alpha channel transparency — converting from PGM will merge transparency into a solid background
  • •PGM files are typically Compact for grayscale images while AVIF files range 40-50% smaller than JPEG/PNG
  • •PGM is optimized for grayscale image processing, scientific data while AVIF is designed for modern web, next-generation web applications — choose based on your specific workflow needs

Advantages of PGM

  • ✓PGM uses lossless compression tailored for Grayscale image processing, scientific data.
  • ✓PGM is supported natively on virtually every device, browser, and operating system.
  • ✓PGM files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓PGM integrates seamlessly with all major creative tools and workflows.

Advantages of AVIF

  • ✓AVIF compresses data using lossy methods, keeping file sizes manageable for Modern web, next-generation web applications.
  • ✓Industry-wide support means AVIF files open anywhere — from legacy systems to the latest devices.
  • ✓Small file sizes make AVIF ideal for email, web uploads, and cloud storage.
  • ✓From VS Code to open-source alternatives, AVIF works out of the box.
