Convert NEF to JPG Without Uploading Anything
NEF is the RAW format used by Nikon cameras. It holds the sensor data before processing, which is great for editing but means most phones, browsers, email clients and websites can't open it. This converter turns your NEF files into standard JPGs right in your browser. Drop in one file or a whole shoot, preview each image with its camera settings, then download them one at a time or all together in a ZIP. Nothing is uploaded, so it's fast and your photos stay private.
How to convert NEF to JPG
- Drag your
.NEFfiles onto the box on the left, or click Add files to choose them. You can add as many as you like. - Pick an Output. Original JPEG is the default and keeps the camera's image exactly as it was saved. Choose a re-encoded size if you need a smaller file.
- Click any file in the list to preview it and see its camera, lens and exposure details.
- Download a single JPG with its download button, or click Download all (ZIP) once more than one file is done.
How This NEF Converter Works
Every NEF file contains a full JPEG version of the photo that your Nikon made when you took the shot. It's the same image you see on the camera's LCD, with your Picture Control, white balance and in-camera corrections already applied. This tool finds that JPEG inside the RAW file and saves it as its own file. On most Nikon DSLRs and Z-series mirrorless cameras the embedded image is full resolution. A few models and settings store a smaller one, and the preview always shows you the exact pixel size you're getting.
Because the JPEG is copied out rather than rebuilt, the Original JPEG option involves no recompression and no quality loss. The tool also adds the camera model, lens, shutter speed, aperture, ISO, focal length, capture date and orientation to the JPG, so the photo still sorts correctly by date and shows the right way up.
Output options
- Original JPEG (no recompression) gives you the camera's own JPEG with its camera details added. It's the fastest option and the best quality.
- Full size, re-encoded keeps the full resolution but lets you set the JPEG quality, which is useful for making files smaller.
- Long edge 4000 / 3000 / 2048 / 1600 px resizes the photo for web pages, email or social media. Images are never enlarged.
- Auto-rotate makes portrait shots display upright. Turn it off to keep the image in the sensor's orientation.
Frequently Asked Questions
Will the JPG be full resolution?
On most Nikon cameras, yes. The JPEG stored inside the NEF matches the sensor resolution, so a 24-megapixel photo comes out at about 6000 × 4000 pixels. Some models and settings store a smaller image. The pixel size is shown under the preview and next to each file.
Does the JPG look the same as the RAW file?
It looks the same as the photo on your camera's screen, with the Picture Control, white balance and lens corrections that were set when you took it. This isn't a RAW editor, so it doesn't recover highlights or let you change exposure. For that, open the NEF in Nikon NX Studio, Lightroom or darktable and export a JPG from there.
Is there any quality loss?
Not with the default Original JPEG output. The image data is copied byte for byte. The re-encode and resize options create a new JPEG at the quality you choose, which makes it smaller but adds a little compression.
Can I convert several NEF files at once?
Yes. Add as many files as you want. They're converted one after another, and Download all (ZIP) saves every finished JPG in one go. If you change the output settings, all the files are converted again with the new settings.
Are my photos uploaded to a server?
No. Everything runs in your browser using JavaScript. Your NEF files never leave your device, and nothing is stored after you close the page.
Is there a file size or number limit?
There's no set limit. Large NEF files from high-resolution cameras like the D850 or Z8 work fine. Very large batches depend on your device's memory, so on a phone or older computer you may want to convert in smaller groups.
Does it work with NRW files?
Yes. NRW is the RAW format used by Nikon Coolpix cameras, and it stores its JPEG the same way. Files from other camera brands usually work too, because most RAW formats keep an embedded JPEG.
Why is my photo sideways in some apps?
With Original JPEG, the rotation is stored as an orientation tag rather than by turning the pixels, which avoids recompression. Nearly every modern app reads that tag. If an older program shows the photo sideways, choose Full size, re-encoded with Auto-rotate on, and the pixels themselves will be rotated.
