The NEF file format stores data in the NEF format. Converting to DOCX produces a document file that stores text and formatting as zipped XML, relying on the reader's installed fonts to render the final layout. This embeds the raster image inside a document container, fixing its dimensions on the page. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. This makes DOCX the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
