NEF file (NEF) stores data in the NEF format. Portable Document Format (PDF) stores fixed-layout pages with embedded fonts, vector graphics, and page geometry defined by ISO 32000. 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. The result is a standard PDF file readable by any compatible application. 1converter handles NEF-to-PDF conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
