NEF To JPG Converter is a free offline image converter for Windows which converts NEF images (Nikon Digital SLR Camera Raw Image format) to commonly used ones like JPG, PNG, GIF, and more. Besides NEF conversion, it can also convert HEIC/HEIF, HDR, ORF, NRW, and other formats to the common ones.
Download and install it from here. Also, a zip version is available from the homepage for portable USB drives.
Using NEF To JPG Converter is easy. After launching it, drag and drop the source NEF or any supported raw format image. Alternatively, click on the window and point to the source image file.
As there is no button to click on to start processing, you would need to change the output file settings before selecting the source image. The default output folder is labeled Output, and the default output format is JPG. To change these, click on them.
You can then select PNG, GIF, BMP, and other destination formats along with a different output folder if needed.
Also, the output quality by default is set to 85 which can be changed. Source photos can also be resized by clicking next to the Photo Resize link to toggle it. The width can be manually set to (in px).
Conversion depends on the file size, and it can take a while. After the processing is complete, the output folder will open and contain the processed images in the formats as chosen before.
It is a simple tool that makes it easy to convert images of high resolution and quality to commonly used formats.
All done.
