An EXR file is a type of raster image saved in the OpenEXR format, which is used to store high dynamic-range (HDR) images. This format can handle multi-layer images, supports both lossy and lossless compression, and works with 16-bit and 32-bit pixel depths. It is widely used in visual effects and animation because it can accurately store detailed image data and multiple image channels.

The Industrial Light & Magic (ILM) company developed the OpenEXR format in 1999 and made it open-source in 2003. Since 2019, the Academy Software Foundation (ASWF) has maintained and updated the format with contributions from major studios like Pixar, Weta Digital, and DreamWorks.

EXR files are mainly used in film production, 3D modeling, and computer-generated imagery (CGI). They are ideal for tasks requiring precise image adjustments and compositing because of their ability to store multiple layers and a wide range of brightness values. Professionals use EXR files to create special effects, animations, and realistic lighting simulations.

How to Open .EXR as OpenEXR Image

You can open EXR files with several image editing and 3D graphics programs, including:
