What is HEIFS?

HEIFS files are built around lossy compression. Designed for ios burst photos, live photos, motion photos, they use the image/heif-sequence MIME type and typically range from varies by content.

What is RAF?

Fujifilm Raw Format (RAF) contains raw sensor data from Fujifilm X-Series and GFX cameras with unique X-Trans sensor processing.

When Should You Use HEIFS vs RAF?

Use HEIFS When...

Reach for HEIFS when your priority is ios burst photos, live photos, motion photos — its efficient compression makes sharing fast and storage minimal.

Use RAF When...

Reach for RAF when your priority is fujifilm photography, film simulation processing — its uncompromising quality ensures every detail is preserved.

HEIFS vs RAF: Key Differences

  • •HEIFS uses lossy compression while RAF uses lossless compression — this is the fundamental technical difference between the two formats.
  • •The switch from lossy compression to lossless compression means you preserve full quality at the expense of larger file sizes.
  • •Transparency: N/A
  • •Storage footprint: varies for HEIFS vs 20-50MB per photo for RAF.
  • •Primary audience: HEIFS is built for ios burst photos, live photos, motion photos scenarios, while RAF focuses on fujifilm photography, film simulation processing — pick the format that matches your output requirement.

Troubleshooting HEIFS to RAF Conversion

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