What is MNG?

Multiple-Image Network Graphics (MNG) is an animation format based on PNG compression, supporting complex frame-based and sprite animations.

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 MNG vs RAF?

MNG vs RAF: Key Differences

• •The core technical difference: MNG relies on lossless compression whereas RAF uses lossless compression.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •Alpha channel support: RAF lacks transparency support.
• •File sizes: MNG files typically range Larger than animated GIF and RAF files 20-50MB per photo.
• •Primary audience: MNG is built for legacy web animation, png-based video clips scenarios, while RAF focuses on fujifilm photography, film simulation processing — pick the format that matches your output requirement.

Advantages of MNG

• ✓MNG compresses data using lossless methods, keeping file sizes manageable for Legacy web animation, PNG-based video clips.
• ✓Industry-wide support means MNG files open anywhere — from legacy systems to the latest devices.
• ✓Lossless quality makes MNG the gold standard for archival and master copies.
• ✓From VS Code to open-source alternatives, MNG 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.

Common Use Cases for MNG to RAF Conversion

• Websites and online content
• Print materials and publications
• Social media posts and ads
• Digital photography and editing
• Graphic design projects
• E-commerce product images

Industry Applications

Best Practices for MNG to RAF Conversion

• →Before converting MNG 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: MNG 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 MNG to RAF Conversion

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