NEF is a raw image file that stores data exactly as it was captured by camera’s sensor. NEF is a proprietary format owned by Nikon, and only Nikon software, codecs, and plugins support it.
Files in the JP2 format are generated by the JPEG 2000 Core Coding software and are used in order to store compressed bitmap images . JP2 files are also known as JPX because they differ only regarding the name of the extension.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the NEF file after converting to JP2 may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from NEF to JP2 to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting NEF to JP2 does not meet your expectations, you can simply try to find on the Internet a different version of your file in NEF format, properly converted to a JP2 file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file NEF the desired result was not achieved, you can try to change the format of NEF file to other than JP2. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your NEF file converted by someone else, and the attempt to convert it to JP2 on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the NEF file in its original format (without conversion to JP2 file). Such a solution will be difficult to implement, but it certainly will give the best result.
