How do I convert NRW files to ICO using LetsConvert?

Upload your NRW file, select ICO as the output format, and optionally choose desired icon sizes (e.g., 16x16, 32x32, 48x48). Click Convert, and the tool will demosaic the raw Nikon image, downscale it to the selected sizes, and generate a .ico file with transparency support. The download starts automatically after processing.

Why should I convert NRW to ICO instead of using PNG or JPEG for icons?

NRW is a raw camera format meant for editing, not for direct use in software. ICO is the standard format for Windows icons, favicons, and shortcuts. Converting to ICO ensures compatibility with Windows and web browsers, supports multiple resolutions in one file, and allows transparency—which PNG lacks for proper icon metadata and JPEG doesn't support at all.

What happens to the raw sensor data and color profile when converting NRW to ICO?

The raw sensor data is demosaiced into a standard 8-bit-per-channel RGB or RGBA image. The color profile is flattened to sRGB for web use, while high bit-depth and EXIF metadata are discarded. Resolution is downscaled to icon sizes (16–256 pixels), and alpha transparency is preserved if the original has it; otherwise, the background becomes opaque. The conversion prioritizes compatibility and small file size over retaining original sensor detail.
