What is AVIF?

AVIF (AV1 Image File Format) is a new image format based on the AV1 video codec. It provides outstanding image quality and compression efficiency.

What is FITS?

Flexible Image Transport System (FITS) is a scientific data format used primarily in astronomy for storing and transmitting images and datasets.

When Should You Use AVIF vs FITS?

AVIF vs FITS: Key Differences

• •The core technical difference: AVIF relies on lossy compression whereas FITS uses lossless compression.
• •The switch from lossy compression to lossless compression means you preserve full quality at the expense of larger file sizes.
• •Transparency: N/A - Scientific data format
• •AVIF files are typically 40-50% smaller than JPEG/PNG while FITS files range Varies from 1MB to several GB
• •AVIF is optimized for modern web, next-generation web applications while FITS is designed for astronomy, scientific imaging, research — choose based on your specific workflow needs

Advantages of AVIF

• ✓At its core, AVIF relies on lossy encoding — a design choice that makes it perfect for Modern web, next-generation web applications.
• ✓You won't run into compatibility issues with AVIF — it's a universal standard across platforms.
• ✓File size management with AVIF: aggressive compression with minimal visible quality loss.
• ✓Every major application in the Modern web, next-generation web applications space supports AVIF natively.

Advantages of FITS

• ✓FITS uses lossless compression tailored for Astronomy, scientific imaging, research.
• ✓FITS is supported natively on virtually every device, browser, and operating system.
• ✓FITS files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓FITS integrates seamlessly with all major creative tools and workflows.

Common Use Cases for AVIF to FITS Conversion

• Digital photography and editing
• Graphic design projects
• E-commerce product images
• Email marketing campaigns
• Presentation graphics
• Blog and article illustrations

Industry Applications

Best Practices for AVIF to FITS Conversion

• →When converting AVIF to FITS, check whether FITS supports transparency — if not, your transparent areas will be filled with a solid color
• →Use FITS for maximum quality archival and AVIF for smaller file sizes when quality is less critical
• →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 AVIF to FITS Conversion

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