"Nikon's NEF files are legendary for quality, but they're huge and proprietary. reaConverter converts them to JPEG with stunning results – the dynamic range is retained, and the colours are spot on. I've processed over 10,000 NEFs with this tool and never had a glitch."

NEF to JXL Conversion: FAQ

What are NEF files?

NEF represents the extension typically associated with RAW images taken with Nikon cameras. Most professional photographers shoot in RAW mode because this allows them to make a series of adjustments during post-processing, including noise removal, white balance or the correction of under/overexposure without reducing the image quality.
