"I had a hard drive full of NEFs from a decade of shooting. reaConverter batch‑converted them all to JPEG with a single click. The older files were processed perfectly – even the ones from my first D40. This tool is a time machine for my photos."

"Nikon's NEF files are legendary for quality, but they're huge and proprietary. reaConverter converts them to JPEG with stunning results – the dynamic range is retained, and the colours are spot on. I've processed over 10,000 NEFs with this tool and never had a glitch."

NEF to PGM Conversion: FAQ

What are NEF files?

NEF represents the extension typically associated with RAW images taken with Nikon cameras. Most professional photographers shoot in RAW mode because this allows them to make a series of adjustments during post-processing, including noise removal, white balance or the correction of under/overexposure without reducing the image quality. As opposed to JPEG or other compressed formats, which include predefined values for aspects such as white balance or brightness and color depth, RAW images allow the photographer more freedom in shaping how the final image will actually look.

What are PGM files?

The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
