What is HEIFS?

HEIF Sequence, burst photo format from Apple cameras — stored as image/heif-sequence — uses lossy encoding to handle ios burst photos, live photos, motion photos. 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 HEIFS vs FITS?

Use HEIFS When...

Reach for HEIFS when your priority is ios burst photos, live photos, motion photos — 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.

HEIFS vs FITS: Key Differences

  • •The core technical difference: HEIFS 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.
  • •Alpha channel support: FITS lacks transparency support.
  • •File sizes: HEIFS files typically range N/A and FITS files Varies from 1MB to several GB.
  • •Primary audience: HEIFS is built for ios burst photos, live photos, motion photos scenarios, while FITS focuses on astronomy, scientific imaging, research — pick the format that matches your output requirement.

Advantages of HEIFS

  • ✓HEIFS uses lossy compression tailored for iOS burst photos, Live Photos, motion photos.
  • ✓HEIFS is supported natively on virtually every device, browser, and operating system.
  • ✓HEIFS files are compact and quick to transfer, even over slow connections.
  • ✓HEIFS integrates seamlessly with all major photo editing tools and workflows.

Advantages of FITS

  • ✓At its core, FITS relies on lossless encoding — a design choice that makes it perfect for Astronomy, scientific imaging, research.
  • ✓You won't run into compatibility issues with FITS — it's a universal standard across platforms.
  • ✓File size management with FITS: larger files guaranteed to match the original exactly.
  • ✓Every major application in the Astronomy, scientific imaging, research space supports FITS natively.

Best Practices for HEIFS to FITS Conversion

  • →When converting HEIFS 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 HEIFS 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 HEIFS to FITS Conversion

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

FAQs

Is converting HEIFS to FITS free?

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

How long does it take to convert HEIFS to FITS?

Most HEIFS 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 HEIFS to FITS lose quality?

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

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

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

Will transparency be preserved when converting HEIFS to FITS?

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