How do I convert ICO to PEF using LetsConvert?

Start by uploading your ICO file to the converter. Select PEF as the target format and choose any optional settings, such as resolution or background color. Then click 'Convert' to process the file, and download your new PEF immediately. The whole process takes seconds, and you can batch-convert multiple ICO files by selecting them all at once.

Why should I convert an ICO to PEF?

ICO is a raster image format designed for Windows icons, with support for multiple sizes and alpha transparency. PEF (Pentax Electronic File) is a raw format from Pentax cameras, storing uncompressed sensor data for maximum editing flexibility in photography. Converting an ICO to PEF allows you to open and edit the icon in raw-capable photo editors like Pentax Digital Camera Utility or Adobe Lightroom, or to use it as a custom texture in 3D applications that expect raw sensor metadata.

What happens to transparency and color data during ICO to PEF conversion?

During the conversion, the ICO's alpha channel is preserved as a separate transparency channel in the PEF output, so icons with transparent backgrounds remain transparent. Color profiles and DPI metadata are carried over if present in the source. Since PEF is a lossless raw format, the pixel data is not compressed or altered, ensuring the converted file retains the exact same color values as the original ICO.
