What is HEIF?

HEIF (High Efficiency Image File Format) is a modern container format that stores images encoded with the HEVC (H.265) codec. It delivers significantly smaller file sizes than JPEG while maintaining superior image quality.

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 HEIF vs ORF?

Use HEIF When...

Reach for HEIF when your priority is modern photography, ios/macos workflows, efficient storage and sharing — 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.

HEIF vs ORF: Key Differences

  • •The core technical difference: HEIF relies on lossy compression whereas ORF uses lossless compression.
  • •Moving from HEIF (lossless) to ORF (lossless) means the output file will be larger — but every bit of the original is preserved.
  • •How transparency is handled: ORF supports transparency, so alpha information is preserved during conversion.
  • •HEIF files are typically 40-50% smaller than equivalent JPEG while ORF files range 15-40MB per photo
  • •Primary audience: HEIF is built for modern photography, ios/macos workflows, efficient storage and sharing scenarios, while ORF focuses on olympus camera raw processing — pick the format that matches your output requirement.

Advantages of HEIF

  • ✓HEIF uses lossy compression tailored for Modern photography, iOS/macOS workflows, efficient storage and sharing.
  • ✓HEIF is supported natively on virtually every device, browser, and operating system.
  • ✓HEIF files are compact and quick to transfer, even over slow connections.
  • ✓HEIF integrates seamlessly with all major photo editing tools and workflows.

Advantages of ORF

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

Troubleshooting HEIF to ORF Conversion

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

FAQs

Is converting HEIF to ORF free?

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

How long does it take to convert HEIF to ORF?

Most HEIF 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 HEIF to ORF lose quality?

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

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

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

Will transparency be preserved when converting HEIF to ORF?

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