NEF to JPG Converter
Nikon's NEF files hold everything the sensor saw, which is why they're big and why almost nothing but photo software will open them. Convert them to JPG here, without uploading a thing.
Works offline — everything it needs is already on your device.
NEF (Nikon Electronic Format) covers the whole Nikon line — the D750, D850, D780, D500 and D7500 DSLRs, and the Z5, Z6, Z7, Z8 and Z9 mirrorless bodies. Depending on the camera and how it's configured a NEF holds 12-bit or 14-bit data and may be uncompressed, lossless compressed, or lossy compressed, which is why two files from the same shoot can differ in size by a factor of two. Nikon's own NX Studio reads all of it but is a full desktop install, and the Z8 and Z9 added High Efficiency (HE and HE*) raw, a newer variant older converters often won't touch.
Conversion runs on your own device with a WebAssembly RAW engine and the embedded preview as a fallback, so nothing is uploaded and there's no daily limit. Compact Coolpix cameras write .NRW, a close relative, and those work here too — or drop a mixed set into RAW to JPG.
Best for
- Getting shareable JPGs off a Nikon card without installing NX Studio
- Opening NEF files on a borrowed or work computer
- Converting a batch before sending to a lab or client
Good to know
High Efficiency (HE/HE*) raw from the Z8 and Z9 is the most likely to fall back to the embedded preview rather than a full demosaic. The result is still full resolution, but it carries the Picture Control that was set on the camera.
