What is ARW?

Sony Alpha Raw (ARW) is Sony's proprietary raw image format containing unprocessed sensor data from Sony Alpha and Cyber-shot cameras.

What is HEIC?

HEIC (High Efficiency Image Container) is a modern image format developed by the HEVC industry group. It uses advanced compression to achieve much smaller file sizes than JPEG.

When Should You Use ARW vs HEIC?

Use ARW When...

Reach for ARW when your priority is sony camera post-processing, professional editing — its uncompromising quality ensures every detail is preserved.

Use HEIC When...

Reach for HEIC when your priority is ios photography, mobile devices — its efficient compression makes sharing fast and storage minimal.

ARW vs HEIC: Key Differences

  • •ARW uses lossless compression while HEIC uses lossy compression — this is the fundamental technical difference between the two formats.
  • •Moving from ARW (lossy) to HEIC (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
  • •How transparency is handled: HEIC does not support alpha channels — transparent areas in the source will become opaque.
  • •Storage footprint: 20-40MB per photo for ARW vs 50% smaller than equivalent JPEG for HEIC.
  • •Use case fit: ARW targets sony camera post-processing, professional editing and HEIC targets ios photography, mobile devices — your choice depends on which workflow stage you are serving.

Advantages of ARW

  • ✓ARW uses lossless compression tailored for Sony camera post-processing, professional editing.
  • ✓ARW is supported natively on virtually every device, browser, and operating system.
  • ✓ARW files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓ARW integrates seamlessly with all major creative tools and workflows.

Advantages of HEIC

  • ✓HEIC compresses data using lossy methods, keeping file sizes manageable for iOS photography, mobile devices.
  • ✓Industry-wide support means HEIC files open anywhere — from legacy systems to the latest devices.
  • ✓Small file sizes make HEIC ideal for email, web uploads, and cloud storage.
  • ✓From Adobe Photoshop to open-source alternatives, HEIC works out of the box.

Troubleshooting ARW to HEIC Conversion

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