How to Convert ICO to EXR

OpenEXR, developed by Industrial Light & Magic, stores image data in 16 or 32-bit floating point and is the standard working format for VFX and compositing software like Nuke, Blender, and After Effects. ICO stores standard 8-bit integer color, so converting ICO to EXR doesn't add dynamic range that wasn't in the original file — it simply changes the container format to one that fits naturally into a VFX pipeline, occasionally useful when a UI icon needs to be composited into a rendered scene as a reference overlay.

This is an uncommon conversion, since icon design and VFX compositing are largely separate disciplines, but the process works the same way as any other format change.

1. Install Batchify Image Converter and Resizer Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single ICO.
3. Drag your ICO file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to ICO and the "To" format to EXR.
5. Click Convert. EXR files are written to the output folder, fully offline.
