What is the EXR file format?

OpenEXR (EXR) is a high-dynamic-range, multi-channel raster image format widely used in VFX and animation pipelines.

EXR file characteristics

Data typeImage
MIME typeimage/x-exr
CompressionOptional; multiple lossless and lossy methods are available
Color depthCommonly 16-bit float per channel (half) or 32-bit float; can also store 32-bit unsigned integer channels
Color spaceTypically scene-linear RGB; color characteristics may be described via chromaticities/white point and related header attributes
Transparency supportYes
Animation supportNo
Resolution supportAny; tiled files can store multi-resolution images (mipmaps/ripmaps) in a single file
MetadataMetadata is stored as typed header attributes (required and optional). OpenEXR supports arbitrary extra attributes; common ones include dataWindow/displayWindow, pixelAspectRatio, lineOrder, compression, and many pipeline/camera/color fields
Standard / SpecificationOpenEXR file format specification (ASWF OpenEXR project)
Typical file sizeHighly variable. Uncompressed 4K RGBA half-float is ~63 MiB per frame; lossless compression often reduces photographic/grainy images to roughly 35–55% of uncompressed size; multi-layer/deep data increases size
Year introduced2003

Advantages

The EXR file format offers several advantages that make it suitable for common use cases.

  • High dynamic range and scene-linear workflow;
  • Arbitrary channels/AOVs in one file;
  • Efficient lossless and lossy compression options;
  • Tiled storage and multi-resolution for large images;
  • Multi-part and multi-view support;
  • Deep data support;
  • Rich metadata;
  • Industry-standard in VFX/animation

Limitations

The EXR file format has certain limitations that may affect its use in specific scenarios.

  • Compatibility can vary by pixel type and compression method;
  • Multi-part/deep workflows generally require OpenEXR 2.0+ capable readers;
  • No built-in encryption/authentication;
  • Frame sequences require disciplined naming/storage management

Compatibility

EXR images are widely supported and can be viewed on most devices and platforms.

  • Supported platforms: Windows, macOS, Linux (widely supported in VFX/CG tools and libraries)
  • Supported devices: Workstations, render farms, VFX/animation pipelines
  • Browser support: No
  • Mobile support: No
  • Backward compatibility: Yes

Security considerations

Treat EXR as untrusted input: complex headers/attributes, optional deep data, and compression require strict bounds checks. Keep decoders and image tools updated
