FAQs

Is converting FITS to HEIFS free?

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

How long does it take to convert FITS to HEIFS?

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

What is HEIFS best used for?

HEIFS is ideal for ios burst photos, live photos, motion photos. HEIF Sequence, burst photo format from Apple cameras

Does converting FITS to HEIFS lose quality?

Yes, converting FITS to HEIFS uses lossy compression, which reduces file size by discarding some visual data. Set quality to 85-95% for a good balance of quality and file size.

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

HEIFS files are typically 50-80% smaller than FITS files because HEIFS uses efficient lossy compression. The exact reduction depends on quality settings.

Will transparency be preserved when converting FITS to HEIFS?

No, HEIFS does not support transparency. Any transparent areas in your FITS will be filled with a solid color (usually white) during conversion. Use PNG or WebP if transparency is needed.

What is FITS?

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

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.

When Should You Use FITS vs HEIFS?

Use FITS When...

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

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.

FITS vs HEIFS: Key Differences

•The core technical difference: FITS relies on lossless compression whereas HEIFS uses lossy compression.
•The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
•Alpha channel support: HEIFS handles transparency, so semi-transparent pixels from the source will be lost.
•File sizes: FITS files typically range Varies from 1MB to several GB and HEIFS files N/A.
•FITS is optimized for astronomy, scientific imaging, research while HEIFS is designed for ios burst photos, live photos, motion photos — choose based on your specific workflow needs

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.

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.

Troubleshooting FITS to HEIFS Conversion

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