How do I convert NEF to JXL with LetsConvert?

Click 'Upload' to select your Nikon .NEF file. Choose JPEG XL as the output format, then toggle 'Lossless' if you want to keep 16-bit color depth. Hit 'Convert' and after a few seconds download your JXL file. No software installation is needed; everything happens in your browser.

What's the advantage of converting NEF to JXL?

NEF files from Nikon cameras are large and often require special software to view. JXL (JPEG XL) is a modern format that can losslessly compress NEF data by 30-50% while preserving 16-bit color, HDR, and dynamic range. It's also natively supported in Chrome, Firefox, and Safari, making it easier to share and archive than a proprietary NEF.

Are color profiles and resolution preserved when converting NEF to JXL?

Our converter demosaics the NEF Bayer sensor data, applies white balance, and maps the embedded ICC color profile (like sRGB, Adobe RGB, or ProPhoto RGB) into the JXL output. Resolution stays identical. In lossless mode there's no quantization loss; in lossy mode, chroma subsampling may slightly reduce fine detail, but file size drops significantly.
