What is an NRW file?

An NRW file is a camera raw image produced by high-end Nikon COOLPIX digital cameras. It stores image data in an uncompressed format that can be processed on the camera or on a computer after the image is captured. NRW files are similar to .NEF files, but are designed to support Windows Imaging Component (WIC) functions.

NRW files are often large (typically around 22MB) since they store 12-bit RGB CCD-RAW camera information at a high resolution and are saved in an uncompressed format. The large amount of image data saved in an NRW file enables you to edit the image's color, shadows, brightness, warmth, and contrast more accurately. Also, NRW files store image adjustments separately from the image data, which means you can undo changes you apply to the image.

NOTE: To capture images in the NRW format on a COOLPIX camera, select the NRW or RAW option in the camera menu.

How to open an NRW file

You can open an NRW file with various image editing programs, including Nikon's ViewNX2 software. You can also open NRW files with Microsoft Photos (bundled with Windows) and Apple Preview (bundled with macOS).

Some other image editors that support NRW files include Adobe Photoshop (Windows and macOS) and Corel PaintShop Pro (Windows).
