What is RAF?

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

What is RAW?

Camera RAW is a file format containing unprocessed sensor data captured directly from a digital camera sensor, providing maximum flexibility for professional photo editing.

When Should You Use RAF vs RAW?

RAF vs RAW: Key Differences

• •RAF and RAW diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both RAF and RAW use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •How transparency is handled: RAW supports transparency, so alpha information is preserved during conversion.
• •RAF files are typically 20-50MB per photo while RAW files range 20-50MB per photo depending on camera
• •Use case fit: RAF targets fujifilm photography, film simulation processing and RAW targets professional photography, post-processing, editing — your choice depends on which workflow stage you are serving.

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.

Advantages of RAW

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

Common Use Cases for RAF to RAW Conversion

• Video thumbnail creation
• Certificate and badge design
• Websites and online content
• Print materials and publications
• Social media posts and ads
• Digital photography and editing

Industry Applications

Best Practices for RAF to RAW Conversion

• →Before converting RAF to RAW, decide whether you need maximum quality or smallest file size — this determines which format truly fits
• →Save a master copy in a lossless format before converting to RAW — you cannot recover detail lost during lossy compression
• →Check the color profile: RAF images may use a wider gamut than RAW supports, causing a visible shift after conversion
• →Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
• →Run a single test conversion first to verify quality meets your standards
• →Strip unnecessary metadata to reduce file size after conversion

Troubleshooting RAF to RAW Conversion

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