This article describes what an EXR file is and how to open it or convert it to another image format.

A file with the EXR file extension is an OpenEXR Bitmap File. It is an open-source high-dynamic-range image file format created by the Industrial Light & Magic visual effects company.

Files in this format are used by various photo editing, visual effects, and animation programs, as they can store high-quality images, feature lossless or lossy compression, support multiple layers, and preserve a high range of brightness and color.

More information about this format can be found on the official OpenEXR website.
