Understanding EXR and AVIF Formats

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

Source 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

Target Format

AVIF Image

image/avif

AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec, offering significantly better compression than JPEG and WebP. It supports both lossy and lossless compression, HDR, wide color gamut, alpha transparency, and animated sequences. AVIF is developed as a royalty-free open standard by the Alliance for Open Media.

Advantages

  • Superior compression efficiency, often 50% smaller than JPEG at equivalent quality
  • Supports HDR, wide color gamut (10-bit and 12-bit), and alpha transparency
  • Royalty-free and open standard with growing browser support

Limitations

  • Encoding is significantly slower than JPEG or WebP
  • Not yet universally supported in all browsers and image editors
  • Maximum image dimension limitations in some implementations

Common Uses

  • Next-generation web image optimization for bandwidth savings
  • High-quality HDR image delivery on supporting platforms
  • Progressive replacement for JPEG and WebP in web applications
