The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPG is a commonly used method of lossy compression for digital images, particularly those produced by digital photography. RAW image formats are intended to capture as closely as possible the scene's characteristics to include light intensity and colors. RAW files are named so because they are not yet processed and ready to be printed or edited with a bitmap graphics editor. RAW file formats contain minimally processed data from the digital camera's image sensor - the metadata includes information about the lens, the settings, the camera's identification, and other data.

This compression can affect quality, but this loss of quality isn’t noticeable to most users.NEF, otherwise known as the Nikon Electronic Format, is Nikon's RAW file format. JPG is a ‘lossy’ format, meaning that it is compressed to save storage space and make it easier to share. JPEG stands for Joint Photographic Experts Group, which is the name of the committee that standardised the format. However, you can usually adjust settings to save into other formats if needed. Many cameras, smartphones, and basic photo or drawing programs will automatically save into JPG format.

JPGs are 2D pixel-based ‘raster’ images, which makes them better for photographs or scans, rather than digital illustrations which are often better as ‘vector’ images.

JPG is a universal format which can be opened by almost all image-viewing or -editing programs, by web browsers, and by certain other apps, and they’re supported by most devices. JPG, or JPEG, is one of the most widely used digital image formats. Nikon also has its own photo-processing application for different operating systems. Nikon is an extremely popular camera brand, so you can open NEF files in most photo viewers and editors, including Microsoft Photos, Google Photos, Apple Photos, Apple Preview, Adobe Photoshop, Corel PaintShop Pro and Canvas. Nikon recommends converting photos afterwards to share them, rather than before. However, although they’re big files, raw images are generally preferred for editing or printing, because more details in the image are preserved. You can change your camera settings to save the files into a different format on the camera’s memory card. Raw NEF images contain the image captured on the camera’s sensor and also metadata, including details of the camera model, and the date and time the camera was set to.

It’s the file extension for photographs taken on a Nikon digital camera. An NEF file is a raw digital image in Nikon Electronic Format.
