Understanding HEIF and CR2 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

Canon Raw Image

image/x-canon-cr2

CR2 (Canon Raw version 2) is Canon's proprietary raw image format used by Canon DSLR and mirrorless cameras. It stores unprocessed sensor data with full bit depth, white balance, and exposure settings as metadata rather than baked-in adjustments. CR2 files provide maximum flexibility for post-processing, preserving all the data captured by the camera sensor.

Advantages

  • Preserves complete unprocessed sensor data for maximum editing flexibility
  • Widely supported by major photo editing software including Lightroom and Capture One
  • Contains extensive EXIF metadata including camera settings and lens information

Limitations

  • Proprietary format controlled by Canon with no public specification
  • Large file sizes, typically 20-30 MB per image for modern cameras
  • Requires specialized raw processing software to view and edit

Common Uses

  • Professional and enthusiast photography with Canon cameras
  • Non-destructive photo editing and raw development
  • High-quality image archival preserving maximum sensor data
