What is QOI?

QOI (Quite OK Image) is a lossless image format designed for simplicity and performance. It offers fast encoding and decoding with compression ratios comparable to PNG, making it ideal for game development and real-time applications.

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 QOI vs RAF?

QOI vs RAF: Key Differences

• •QOI and RAF diverge on compression: lossless compression for the source, lossless compression for the target.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •Transparency: N/A
• •Storage footprint: Similar to PNG, typically 20-30% smaller than uncompressed data for QOI vs 20-50MB per photo for RAF.
• •QOI is optimized for game development, pixel art, embedded systems, quick texture loading while RAF is designed for fujifilm photography, film simulation processing — choose based on your specific workflow needs

Advantages of QOI

• ✓QOI applies lossless compression specifically calibrated for Game development, pixel art, embedded systems, quick texture loading.
• ✓QOI enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓QOI guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find QOI support built into virtually every tool that handles Game development, pixel art, embedded systems, quick texture loading — no plugins or converters needed.

Advantages of RAF

• ✓RAF compresses data using lossless methods, keeping file sizes manageable for Fujifilm photography, film simulation processing.
• ✓Industry-wide support means RAF files open anywhere — from legacy systems to the latest devices.
• ✓Lossless quality makes RAF the gold standard for archival and master copies.
• ✓From Adobe Photoshop to open-source alternatives, RAF works out of the box.

Common Use Cases for QOI to RAF Conversion

• Digital art portfolios
• Brochure and flyer design
• Newsletter graphics
• Video thumbnail creation
• Certificate and badge design
• Websites and online content

Industry Applications

Best Practices for QOI to RAF Conversion

• →When converting QOI to RAF, check whether RAF supports transparency — if not, your transparent areas will be filled with a solid color
• →Use RAF for maximum quality archival and QOI for lossless workflows
• →Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
• →Maintain original aspect ratio to avoid distortion during conversion
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting QOI to RAF Conversion

• !RAF shows visible compression artifacts → lower the compression level or switch to a lossless variant
• !The converted RAF image looks washed out → the source QOI likely uses a wider color space than RAF supports
• !RAF file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
• !Text in the converted RAF looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
