When Should You Use HDR vs AVIF?

Use HDR When...

Reach for HDR when your priority is hdri lighting, panoramic photography — 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.

HDR vs AVIF: Key Differences

  • •HDR 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.
  • •Alpha channel support: AVIF handles transparency, so semi-transparent pixels from the source will be lost.
  • •Storage footprint: 5-30MB for typical HDR maps for HDR vs 40-50% smaller than JPEG/PNG for AVIF.
  • •HDR is optimized for hdri lighting, panoramic photography while AVIF is designed for modern web, next-generation web applications — choose based on your specific workflow needs

Advantages of HDR

  • ✓HDR uses lossless compression tailored for HDRI lighting, panoramic photography.
  • ✓HDR is supported natively on virtually every device, browser, and operating system.
  • ✓HDR files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓HDR integrates seamlessly with all major photo editing tools and workflows.

Advantages of AVIF

  • ✓The lossy nature of AVIF means file sizes stay reasonable while handling Modern web, next-generation web applications efficiently.
  • ✓From mobile devices to enterprise servers, AVIF is recognized and supported everywhere.
  • ✓Storage and bandwidth costs drop significantly when using AVIF thanks to its efficient compression.
  • ✓AVIF is a first-class citizen in all major software ecosystems, from creative suites to development environments.
