How do I convert ICO to EXR?

Upload your ICO file, choose EXR as the target format, and adjust optional settings like bit depth (16-bit or 32-bit float). Click 'Convert' and download the result. The converter automatically selects the largest image from ICO and preserves the alpha channel.

Why should I convert ICO to EXR?

ICO is a container for small Windows icons, typically 8-bit PNG or BMP. EXR (OpenEXR) is a high-dynamic-range format with floating-point precision, widely used in VFX and 3D rendering. Converting lets you embed icon imagery into HDR scenes, retain higher color depth, and utilize lossless or PIZ compression for production workflows.

Does converting ICO to EXR preserve transparency and other attributes?

Yes, the alpha channel from ICO is carried over to EXR. Since EXR supports high bit depth, 8-bit ICO data is upsampled to 16/32-bit float, which technically changes precision but adds headroom. Multi-size ICO icons are flattened to a single EXR image, and DPI metadata is dropped, as EXR relies on scene-linear units.
