NEF to J2K

Upload a NEF camera RAW file and save it as J2K. The converter uses server-side image processing for quick RAW export to common raster formats.

NEF is a format for original, raw graphic files created by Nikon technology. Accordingly, the developer of the format is also the specified company. The name of the format is an abbreviation for Nikon Electronic Format. At the same time, NEF format files received by Nikon cameras of different models can have a different structure, so compatibility is not guaranteed. Nikon's graphic editors are geared towards supporting specific camera models. When creating a file, the data comes directly from the matrix. NEF files are of good quality and contain metadata, and therefore take up a lot of space.

J2K is a raster image category file format. It is a compressed bitmap using wave compression instead of DCT compression, which is used by standard .JPEG images. The format supports 16-bit color, alpha transparency and lossless compression. The file type is JPEG 2000 Image. The J2K file format was developed by the Joint Photographic Experts Group (JPEG). J2K is an update to the JPEG format that includes original features. Say alpha channel support and lossless compression. J2K is a segment of a large package of updated JPEG extensions. They gained fame as JPEG2000. Such as J2C, JPX, JPM or JP2. The lion's share of such formats are combined with the main programs so that you can view images. However, JPEG is particularly popular. For those who specialize in photography, it is important that they have the opportunity to reduce the file size, while saving it on disk with the same frame size and at the same high visual quality. How to get out of this situation? You can, for example, store images in JPEG2000 format with the file extension jp2 or j2k. The compression algorithm and the format itself have been known for over 10 years. Nevertheless, there is no need to talk about its widespread use. That's because his "big brother" JPEG is firmly holding on to its position.
