What is HEIFS?

HEIFS (image/heif-sequence) uses lossy compression optimized for ios burst photos, live photos, motion photos. HEIF Sequence, burst photo format from Apple cameras

What is ORF?

Olympus Raw Format (ORF) contains raw sensor data from Olympus OM-D, PEN, and other Olympus digital cameras.

When Should You Use HEIFS vs ORF?

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 ORF When...

Reach for ORF when your priority is olympus camera raw processing — its uncompromising quality ensures every detail is preserved.

HEIFS vs ORF: Key Differences

  • •HEIFS and ORF diverge on compression: lossy compression for the source, lossless compression for the target.
  • •Converting from HEIFS to ORF changes compression type: lossless source becomes larger but with full quality preservation.
  • •Transparency: N/A
  • •Storage footprint: varies for HEIFS vs 15-40MB per photo for ORF.
  • •Primary audience: HEIFS is built for ios burst photos, live photos, motion photos scenarios, while ORF focuses on olympus camera raw processing — pick the format that matches your output requirement.

Advantages of HEIFS

  • ✓The lossy nature of HEIFS means file sizes stay reasonable while handling iOS burst photos, Live Photos, motion photos efficiently.
  • ✓From mobile devices to enterprise servers, HEIFS is recognized and supported everywhere.
  • ✓Storage and bandwidth costs drop significantly when using HEIFS thanks to its efficient compression.
  • ✓HEIFS is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of ORF

  • ✓ORF applies lossless compression specifically calibrated for Olympus camera raw processing.
  • ✓ORF enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓ORF guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find ORF support built into virtually every tool that handles Olympus camera raw processing — no plugins or converters needed.

Troubleshooting HEIFS to ORF Conversion

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

FAQs

Is converting HEIFS to ORF free?

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

How long does it take to convert HEIFS to ORF?

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

What is ORF best used for?

ORF is ideal for olympus camera raw processing. Olympus Raw Format, raw image from Olympus cameras

Does converting HEIFS to ORF lose quality?

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

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

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

Will transparency be preserved when converting HEIFS to ORF?

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