toolkit Drop a Nikon NEF file below to convert it to JPG right here, in this browser tab. Decoding runs entirely on your device — the file is never uploaded.
What NEF is
NEF is Nikon's raw image format. Nikon also uses the related NRW extension on some compact cameras; both are accepted here and decoded the same way.
Why convert it
A NEF keeps far more of the sensor's original data than a JPEG, which is why photo editors want it — but most viewers, messaging apps, and websites can't open it directly. Converting to JPG gives you something you can view, share, or upload anywhere.
Orientation is preserved
The camera's orientation tag stored in the NEF is read and applied before the pixels are returned, so the output JPG comes out the right way up rather than needing a manual rotate.
Quality control
You can set the output JPEG quality before converting. Since a NEF starts with substantially more detail than a JPEG, a higher quality setting is worth considering if file size isn't a concern.
Frequently asked questions
Is my photo uploaded anywhere?
No. Decoding and JPG encoding both happen locally in your browser via WebAssembly; the NEF file never leaves your device.
Does this also accept NRW files?
Yes — NRW is Nikon's other raw extension, used on some compact cameras, and it's accepted on this page alongside NEF.
Will orientation be correct?
Yes — the NEF's own orientation tag is read and applied automatically before conversion.
Can I convert a JPG back into NEF?
No. NEF decoding is one-way here — there's no encoder that writes NEF files.
Does this apply Nikon Picture Control settings or in-camera edits?
No. This performs a straightforward decode of the raw sensor data in the file; in-camera picture settings and any post-capture edits made in a separate editor aren't applied here.
