NEF to JPG converter
A free NEF to JPG converter that also writes PNG and WebP, entirely in your browser. A Nikon NEF holds everything the sensor recorded, which is why nothing but photo software will open one. This pulls out the full-resolution JPEG your camera already wrote inside the file and converts that — in your browser, with the NEF never leaving your machine.

JPG has no transparency, so transparent areas become white. Converted files don’t keep EXIF or color profile data.
Runs in your browser. Your files never leave your device.
How to convert a NEF
- Add your NEF filesDrag them in or pick them from disk. These are large files, so a batch of them takes a moment to read — nothing is uploaded while that happens.
- Choose an output formatJPG is preselected because getting a shareable photo out of a NEF is the usual reason to be here. PNG gives a lossless copy of the extracted image, WebP the smallest file.
- Convert and downloadThe embedded full-size JPEG is lifted out of each NEF and re-encoded to your chosen format. One file downloads on its own; a batch comes back as a ZIP.
Questions about converting NEF
No. Every NEF contains a full-resolution JPEG that your camera rendered the moment you pressed the shutter, and this tool extracts that JPEG and converts it — fast, with no download, and exactly the image you saw on the camera's screen. Actual raw development — redoing white balance, recovering highlights, applying your own tone curve — needs desktop software like Lightroom, Capture One or the free darktable.
Yes, for essentially every Nikon body. Nikon embeds a preview at the same pixel dimensions as the raw image, so the JPG you get out matches the photo's full size. If a particular file only carries a small thumbnail, the converter fails that row and says so rather than handing you an upscaled postage stamp.
A NEF stores 12 or 14 bits per photosite straight off the sensor, plus the embedded preview and a lot of metadata — commonly 25-50 MB. The extracted JPEG is already compressed for viewing, so it typically lands somewhere between 3 and 10 MB. You are not losing anything the JPEG ever had; the rest of the NEF is raw latitude that only a raw developer can use.
One file is free. Four hundred, on brand, in every size, is what we do.
