What is X3F?

Sigma Raw (X3F) contains raw sensor data from Sigma cameras using the unique Foveon X3 sensor technology.

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.

When Should You Use X3F vs QOI?

Use X3F When...

Reach for X3F when your priority is sigma/foveon camera raw processing — its uncompromising quality ensures every detail is preserved.

Use QOI When...

Reach for QOI when your priority is game development, pixel art, embedded systems, quick texture loading — its uncompromising quality ensures every detail is preserved.

X3F vs QOI: Key Differences

•X3F uses lossless compression while QOI uses lossless compression — both take the same approach to file size management.
•Since both X3F and QOI 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: QOI supports transparency, so alpha information is preserved during conversion.
•File sizes: X3F files typically range 25-60MB per photo and QOI files Similar to PNG, typically 20-30% smaller than uncompressed data.
•Primary audience: X3F is built for sigma/foveon camera raw processing scenarios, while QOI focuses on game development, pixel art, embedded systems, quick texture loading — pick the format that matches your output requirement.

Advantages of X3F

✓The lossless nature of X3F means file sizes stay reasonable while handling Sigma/Foveon camera raw processing efficiently.
✓From mobile devices to enterprise servers, X3F is recognized and supported everywhere.
✓The trade-off for X3F's perfection is larger files — but for archival work, it is worth every megabyte.
✓X3F is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Best Practices for X3F to QOI Conversion

→When converting X3F to QOI, check whether QOI supports transparency — if not, your transparent areas will be filled with a solid color
→Use QOI for maximum quality archival and X3F 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 X3F to QOI Conversion

!QOI shows visible compression artifacts → lower the compression level or switch to a lossless variant
!The converted QOI image looks washed out → the source X3F likely uses a wider color space than QOI supports
!QOI file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
!Text in the converted QOI looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
