What is AVIFS?

AVIF Sequence, animated AVIF image format for modern web — stored as image/avif-sequence — uses lossy encoding to handle modern web animations, high-efficiency image sequences. Typical file sizes: varies by content.

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 AVIFS vs FITS?

Use AVIFS When...

Reach for AVIFS when your priority is modern web animations, high-efficiency image sequences — its efficient compression makes sharing fast and storage minimal.

Use FITS When...

Reach for FITS when your priority is astronomy, scientific imaging, research — its uncompromising quality ensures every detail is preserved.

AVIFS vs FITS: Key Differences

  • •AVIFS uses lossy compression while FITS uses lossless compression — this is the fundamental technical difference between the two formats.
  • •Moving from AVIFS (lossless) to FITS (lossless) means the output file will be larger — but every bit of the original is preserved.
  • •How transparency is handled: FITS supports transparency, so alpha information is preserved during conversion.
  • •FITS files tend to be differently sized than AVIFS
  • •Primary audience: AVIFS is built for modern web animations, high-efficiency image sequences scenarios, while FITS focuses on astronomy, scientific imaging, research — pick the format that matches your output requirement.

Advantages of AVIFS

  • ✓AVIFS uses lossy compression tailored for Modern web animations, high-efficiency image sequences.
  • ✓AVIFS is supported natively on virtually every device, browser, and operating system.
  • ✓AVIFS files are compact and quick to transfer, even over slow connections.
  • ✓AVIFS integrates seamlessly with all major web development tools and workflows.

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.

Best Practices for AVIFS to FITS Conversion

  • →When converting AVIFS 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 AVIFS 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 AVIFS to FITS Conversion

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

FAQs

Is converting AVIFS to FITS free?

Yes, GoConvertFile offers free conversion of AVIFS to FITS for files up to 100MB. No registration required.

How long does it take to convert AVIFS to FITS?

Most AVIFS to FITS conversions complete within seconds for standard-sized files. Larger files may take longer depending on the conversion complexity.

What is FITS best used for?

FITS is ideal for astronomy, scientific imaging, research. Flexible Image Transport System, scientific data format

Does converting AVIFS to FITS lose quality?

No, converting AVIFS to FITS does not cause additional quality loss — FITS uses lossless compression. However, any artifacts already present in the original AVIFS file will persist in the FITS output.

What file size should I expect after converting AVIFS to FITS?

FITS files are typically 2-5x larger than equivalent AVIFS files because FITS preserves all pixel data. This is expected and necessary for lossless quality.

Will transparency be preserved when converting AVIFS to FITS?

Yes, FITS supports transparency. Alpha channel information from AVIFS is preserved during conversion.
