An .nrw file is a camera raw image saved in the Nikon Raw (NRW) format. High-end Nikon COOLPIX digital cameras capture photographs in the NRW format, which stores the image data in an uncompressed format, allowing photographers to edit them more accurately than compressed images and publish them in a higher-quality format.

Since .nrw files are uncompressed, they are typically large, which makes it difficult to share or store a large number of them. Additionally, they are not widely supported by image viewers or editors. You can convert NRW images to the compressed JPEG (.jpg) format, which reduces the size and is more widely supported. However, slight image degradation will occur since the JPEG format is lossy. If you would like to convert an NRW image to a more common image format but not lose the quality of the image, you can choose formats like PNG (.png) or TIFF (.tif), which utilizes (lossless) compression.
