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.
PEF files are generated by Pentax digital cameras. What do PEF files store? A typical PEF file contains a RAW uncompressed image. How Pentax cameras save photos? PEF files store uncompressed RAW images without any additional adjustments made by the Pentax camera software.
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 PEF may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from NEF to PEF 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 PEF 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 PEF 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 PEF. 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 PEF 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 PEF file). Such a solution will be difficult to implement, but it certainly will give the best result.
