Nikon cameras save RAW photos as NEF (Nikon Electronic Format). NEF files are excellent for editing because they keep all the sensor data, but they are big and few things can open them: phones, social networks, web forms, email previews and many photo viewers all need a JPG instead.
This converter turns NEF files into JPGs directly in your browser. It uses the image the camera rendered and stored inside the NEF, so the result has your Picture Control, white balance and exposure exactly as you saw them on the camera. Nothing is installed, and nothing is uploaded.
Before
NEF, Nikon D5300 (24 MP)
≈ 20–30 MB
Needs Nikon or raw-editing software; most apps and websites reject it.
After
JPG, 6000 × 4000
≈ 3–7 MB
Full resolution in our test, with your Picture Control and white balance.
Measured on a sample D5300 NEF. Sizes vary with the scene and the quality setting. The JPG is made from the preview the camera stores inside the NEF; a few older models store a smaller one, and the tool shows the size when that happens.
Drop .NEF files into the workspace above, or click to choose them. Several files can be added at once, up to 100 MB each.
Use 90–100% for prints and archives, or around 80% for smaller files to share.
Click Convert to JPG. Every file is converted on your own device.
Save each JPG individually or download the whole batch as one ZIP.
| Use | Quality | Typical JPG size | Then |
|---|---|---|---|
| Printing and archiving | 100% | 5–9 MB | Keep the NEF as well |
| Sharing with family or clients | 90% | 3–5 MB | Nothing else needed |
| 80% | 2–3 MB | Resize to 2048 px wide | |
| Social media | 85% | 2–4 MB | Resize for the platform |
| Forms with KB limits | 80% | 2–3 MB | Compress to the exact limit |
NEF is the RAW format used by Nikon digital cameras, from the D-series DSLRs (D3500, D5600, D7500, D750, D850 and many more) to the Z-series mirrorless bodies and some COOLPIX models. It is built on the TIFF structure and contains the sensor data (uncompressed, lossless compressed or lossy compressed, depending on your settings), the camera settings, and one or more JPEG previews.
Those previews exist so the camera, and software like Nikon NX Studio, can show the photo instantly without processing the raw data. In most Nikon cameras the largest preview is at the full sensor resolution.
Converting a raw file properly means "developing" it: demosaicing the sensor pattern, applying white balance, a tone curve, colour profile and sharpening. Your camera does all of that each time you take a photo and stores the result inside the NEF. This converter reads that stored image instead of repeating the development, which is why it is fast and why the colours match the camera.
The tool scans the NEF for every embedded JPEG, keeps only complete images, picks the largest, applies the orientation recorded by the camera so portrait shots stand upright, and encodes a JPG at the quality you choose.
In our tests a NEF from a 24-megapixel Nikon D5300 contained three previews (640 × 424, 1620 × 1080 and a full 6000 × 4000), so the JPG came out at full resolution. Most Nikon DSLRs and Z cameras behave the same way. Some older bodies and compact cameras store only a reduced preview; for those, the tool shows the actual output size so you are never surprised.
If you need a full-resolution JPG from a file with a small preview, open it in Nikon NX Studio (free) or another raw developer and export from there.
The reason to shoot NEF is the latitude it gives you later: rescuing a sky that was too bright, opening up shadows, correcting a wrong white balance or cleaning up high-ISO noise. Those edits need a raw developer working on the sensor data. Nikon NX Studio is free; darktable and RawTherapee are free and open source; Lightroom and Capture One are paid.
When the camera already got it right, a full edit is unnecessary. This converter is for those moments: sharing an event with friends, sending proofs, putting a photo on a website, or viewing NEF files on a computer without any Nikon software.
A full-resolution 24 MP JPG at high quality is several megabytes, which is perfect for printing and archiving but larger than needed on screens. For email and social media, resize the photo afterwards with the Image Resizer; around 2048 pixels on the long side is plenty. If a form has a strict size limit, the Image Compressor can hit an exact KB target.
Your NEF files are read from your disk and converted on your device. There is no upload, so there is no waiting for 25 MB files to transfer, and no copy of your photos on anyone else's server. The JPGs are saved straight to your downloads folder, individually or as a ZIP.
EXIF data from the NEF, including the capture time, camera serial number and GPS position, is not copied into the JPG. That makes the JPGs safer to post publicly; keep the NEF originals for your own records.
Turn a day of NEF files into JPGs that open on every phone and computer.
Check photos on a computer where NX Studio or Lightroom isn't installed.
Send camera-look JPGs while you edit the final selection in your raw developer.
Convert, then resize or compress to the size the site expects.
Nikon cameras store a finished JPEG preview inside every NEF file, next to the raw sensor data. The converter extracts the largest preview, turns it upright using the orientation in the file, and saves it as a JPG at your chosen quality. It does not re-develop the raw data.
Usually. A NEF from a 24 MP Nikon D5300 gave a full 6000 × 4000 JPG in our tests, and most Nikon DSLRs and Z cameras embed a full-size preview. Some older or compact models store a smaller one; the tool tells you the output size when a file only contains a small preview.
No. NX Studio is Nikon's free raw editor and is worth installing if you want to adjust exposure or white balance. To simply turn NEF files into JPGs, nothing needs to be installed.
Yes. The preview is rendered by the camera with your Picture Control, white balance and settings such as Active D-Lighting, so the JPG looks like the photo on the camera screen.
Not here. Recovering highlights, lifting shadows or changing white balance works on the raw sensor data and needs a raw developer such as NX Studio, Lightroom, darktable or RawTherapee.
No. They are read and converted in your browser, and the JPGs are saved directly to your device. Nothing is sent to a server.
Z-series NEF files store a camera-rendered preview just like DSLR files and are converted the same way. If any file has no readable preview, the tool says so instead of producing a broken image, and NX Studio can export it instead.
No. The JPG is written from the image pixels without the NEF's EXIF data, so the camera model, lens settings, capture time and location are not included. Keep the NEF originals if you need them; the EXIF viewer shows what they contain.
