FAQs

Is converting X3F to HEIFS free?

Yes, GoConvertFile offers free conversion of X3F to HEIFS for files up to 100MB. No registration required.

How long does it take to convert X3F to HEIFS?

Most X3F 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 X3F to HEIFS lose quality?

Yes, converting X3F 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 X3F to HEIFS?

HEIFS files are typically 50-80% smaller than X3F files because HEIFS uses efficient lossy compression. The exact reduction depends on quality settings.

Will transparency be preserved when converting X3F to HEIFS?

No, HEIFS does not support transparency. Any transparent areas in your X3F will be filled with a solid color (usually white) during conversion. Use PNG or WebP if transparency is needed.

What is X3F?

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

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 X3F vs HEIFS?

Use X3F When...

Reach for X3F when your priority is sigma/foveon camera raw processing — 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.

X3F vs HEIFS: Key Differences

•X3F uses lossless compression while HEIFS uses lossy compression — this is the fundamental technical difference between the two formats.
•Moving from X3F (lossy) to HEIFS (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
•Alpha channel support: HEIFS handles transparency, so semi-transparent pixels from the source will be lost.
•Storage footprint: 25-60MB per photo for X3F vs varies for HEIFS.
•Primary audience: X3F is built for sigma/foveon camera raw processing scenarios, while HEIFS focuses on ios burst photos, live photos, motion photos — pick the format that matches your output requirement.

Advantages of X3F

✓X3F compresses data using lossless methods, keeping file sizes manageable for Sigma/Foveon camera raw processing.
✓Industry-wide support means X3F files open anywhere — from legacy systems to the latest devices.
✓Lossless quality makes X3F the gold standard for archival and master copies.
✓From professional software to open-source alternatives, X3F works out of the box.

Advantages of HEIFS

✓HEIFS applies lossy compression specifically calibrated for iOS burst photos, Live Photos, motion photos.
✓HEIFS enjoys broad native support across operating systems, browsers, and creative tools alike.
✓HEIFS delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
✓You will find HEIFS support built into virtually every tool that handles iOS burst photos, Live Photos, motion photos — no plugins or converters needed.

Troubleshooting X3F to HEIFS Conversion

!Converting X3F to HEIFS gives blurry output → increase the quality setting before conversion
!Colors look different in HEIFS than X3F → 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 X3F turned white in HEIFS → HEIFS may not support transparency
