What is JXL?

JXL (image/jxl) uses lossy compression optimized for modern web, archival photography, high-quality imaging. JPEG XL, next-generation image format with superior compression and quality

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 JXL vs RAF?

JXL vs RAF: Key Differences

• •JXL uses lossy compression while RAF uses lossless compression — this is the fundamental technical difference between the two formats.
• •Converting from JXL to RAF changes compression type: lossless source becomes larger but with full quality preservation.
• •How transparency is handled: RAF supports transparency, so alpha information is preserved during conversion.
• •File sizes: JXL files typically range N/A and RAF files 20-50MB per photo.
• •Primary audience: JXL is built for modern web, archival photography, high-quality imaging scenarios, while RAF focuses on fujifilm photography, film simulation processing — pick the format that matches your output requirement.

Advantages of JXL

• ✓JXL applies lossy compression specifically calibrated for Modern web, archival photography, high-quality imaging.
• ✓JXL enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓JXL delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
• ✓You will find JXL support built into virtually every tool that handles Modern web, archival photography, high-quality imaging — no plugins or converters needed.

Advantages of RAF

• ✓RAF applies lossless compression specifically calibrated for Fujifilm photography, film simulation processing.
• ✓RAF enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓RAF guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find RAF support built into virtually every tool that handles Fujifilm photography, film simulation processing — no plugins or converters needed.

Common Use Cases for JXL to RAF Conversion

• Blog and article illustrations
• Mobile app UI assets
• Product photography for marketplaces
• Digital art portfolios
• Brochure and flyer design
• Newsletter graphics

Industry Applications

Best Practices for JXL to RAF Conversion

• →Before converting JXL to RAF, 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 RAF — you cannot recover detail lost during lossy compression
• →Check the color profile: JXL images may use a wider gamut than RAF 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 JXL to RAF Conversion

• !Converting JXL to RAF gives blurry output → increase the quality setting before conversion
• !Colors look different in RAF than JXL → 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 JXL turned white in RAF → RAF may not support transparency
