NEF converter
Convert your NEF files to any format.
What is a NEF file?
NEF is Nikon's RAW format — every photographic detail the sensor captured, before any in-camera processing, editable but unreadable by most everyday software.
First released in 1999 by Nikon, it uses lossless compression and no transparency, which makes it best suited to unprocessed camera sensor data from Nikon DSLRs and mirrorless cameras.

Advantages of the NEF format
Maximum editing latitude
NEF stores the sensor's raw measurements rather than a baked-in interpretation, so exposure, white balance and color can be adjusted after the fact with far less quality loss than editing a JPG.
Higher bit depth
Typically 12 or 14 bits per channel versus JPG's 8, capturing far smoother gradients and more recoverable detail in shadows and highlights.
Nothing discarded
Unlike JPG, no in-camera sharpening, noise reduction or compression is baked in — the file is the closest thing to what the sensor actually saw.

NEF: frequently asked questions
Why can't I just open my NEF file like a normal photo?
NEF stores raw, undebayered sensor data — it needs a RAW processing pipeline (demosaicing, color matrix, white balance) to become a viewable image, which most everyday apps and browsers don't include.
Will I lose quality converting NEF to JPG?
Some — JPG is lossy and limited to 8 bits per channel, while NEF typically holds 12–14 bits of latitude. For sharing and viewing the difference is invisible; for serious editing, keep the original NEF.
Is the conversion private?
Yes — your NEF is decoded and converted entirely inside your browser via a WebAssembly build of LibRaw; nothing is uploaded to a server.
Why is my NEF file so large?
It stores the sensor's full raw measurements at high bit depth with little to no compression, which is exactly what gives it so much editing latitude.
