Understanding HEIF and EXR 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

OpenEXR Image

image/x-exr

OpenEXR is a high dynamic range raster image format developed by Industrial Light & Magic for use in visual effects and motion picture production. It supports 16-bit and 32-bit floating-point pixels, multiple compression methods, arbitrary image channels, and multi-part files. OpenEXR is the industry standard for storing intermediate and final rendered frames in VFX pipelines.

Advantages

  • Industry-standard 16-bit and 32-bit floating-point precision for VFX work
  • Supports an arbitrary number of named channels and deep image data
  • Multiple lossless and lossy compression options including PIZ and DWAA

Limitations

  • Large file sizes even with compression, especially for 32-bit data
  • Not supported by web browsers or most consumer image viewers
  • Complex format specification requires specialized libraries to read and write

Common Uses

  • Visual effects compositing and intermediate renders in film production
  • 3D rendering output for lighting and shading passes
  • HDR image storage for professional color grading and post-production
