AVIFS vs RAF: Key Differences

  • •AVIFS and RAF diverge on compression: lossy compression for the source, lossless compression for the target.
  • •Moving from AVIFS (lossless) to RAF (lossless) means the output file will be larger — but every bit of the original is preserved.
  • •Alpha channel support: RAF lacks transparency support.
  • •File sizes: AVIFS files typically range N/A and RAF files 20-50MB per photo.
  • •Primary audience: AVIFS is built for modern web animations, high-efficiency image sequences scenarios, while RAF focuses on fujifilm photography, film simulation processing — pick the format that matches your output requirement.

Advantages of AVIFS

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

Advantages of RAF

  • ✓At its core, RAF relies on lossless encoding — a design choice that makes it perfect for Fujifilm photography, film simulation processing.
  • ✓You won't run into compatibility issues with RAF — it's a universal standard across platforms.
  • ✓File size management with RAF: larger files guaranteed to match the original exactly.
  • ✓Every major application in the Fujifilm photography, film simulation processing space supports RAF natively.

Troubleshooting AVIFS to RAF Conversion

  • !Converting AVIFS to RAF gives blurry output → increase the quality setting before conversion
  • !Colors look different in RAF than AVIFS → check color profile mismatch (sRGB vs Adobe RGB)
