Understanding HEIF and ARW Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

HEIF Image

image/heif

HEIF (High Efficiency Image Format) is an image container format standardized by MPEG that can store still images and image sequences using various codecs, most commonly HEVC. It was designed to supersede JPEG by offering better compression, higher quality, and richer features such as image derivations and non-destructive edits. HEIF serves as the underlying standard for Apple HEIC format.

Advantages

  • Superior compression efficiency over JPEG with better image quality
  • Supports non-destructive editing operations stored as metadata
  • Flexible container supporting multiple codecs and image sequences

Limitations

  • Limited native support on Windows and many Linux distributions
  • Codec patent licensing can complicate open-source implementations
  • Not directly supported in web browsers for inline display

Common Uses

  • High-quality photo storage with reduced file sizes
  • Image sequences and derived images in photography workflows
  • Apple ecosystem photo storage and sharing

Target Format

Sony Raw Image

image/x-sony-arw

ARW (Alpha Raw) is Sony's proprietary raw image format used by Sony Alpha mirrorless and DSLR cameras. Based on the TIFF specification, it stores unprocessed 12-bit or 14-bit sensor data with complete metadata. ARW files can be either uncompressed or use Sony's lossy or lossless compressed raw encoding.

Advantages

  • Preserves full unprocessed sensor data for maximum post-processing latitude
  • Supports both compressed and uncompressed raw storage options
  • Well-supported by major photo editing applications including Lightroom and Capture One

Limitations

  • Proprietary format with no publicly available specification
  • Large file sizes, especially in uncompressed mode
  • Requires raw-capable software for viewing and editing

Common Uses

  • Professional photography with Sony Alpha series cameras
  • Raw photo editing and non-destructive development
  • High-quality archival of photographic captures
