What changes when you convert NEF to JP2

NEF files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to JP2 bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after.

"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 JP2 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. As opposed to JPEG or other compressed formats, which include predefined values for aspects such as white balance or brightness and color depth, RAW images allow the photographer more freedom in shaping how the final image will actually look.

What are JP2 files?

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
