How to Convert RAW to EXR

Of all the source formats that get converted to EXR, RAW is the one that actually has a legitimate claim to extended dynamic range, since camera sensors typically capture somewhere between 12 and 14 stops of light, well beyond what an 8-bit JPG can represent. OpenEXR's floating-point storage, used throughout VFX and film production, can actually preserve more of that captured range than a standard demosaiced export would, making RAW to EXR a meaningful conversion for photographers or visual effects artists who want to retain highlight and shadow detail for compositing or color grading work.

This is different from converting an already-processed 8-bit photo to EXR, where the conversion just changes the container without adding real dynamic range — with RAW as the source, there's genuine extended sensor data to carry into EXR's higher-precision format.

1. Install Turbo Batch Image Converter Pro, which supports 47 RAW camera formats.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single RAW file.
3. Drag your RAW files or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to RAW (or your specific camera format) and the "To" format to EXR.
5. Click Convert. EXR files are written to the output folder, fully offline.
