Nikon RAW (NEF)
.nef · image/x-nikon-nef · 1999 · Nikon
Nikon RAW files. Develop to JPEG or PNG right in your browser. Below is what NEF is best at, where it falls short, and how it compares — plus free, in-browser tools to convert NEF to and from other formats, with nothing uploaded.
NEF is Nikon's RAW format — unprocessed sensor data straight from the camera, 12/14-bit, with maximum editing latitude and zero compatibility with everyday software. EditItAll decodes NEF with a native RAW engine and exports standard JPEG, PNG or WebP locally, without uploading your photos anywhere.

Frequently asked questions
Is NEF lossy or lossless?+
NEF is lossless: it preserves every pixel exactly, with no quality loss.
Does NEF support transparency?+
No — NEF has no alpha channel, so transparent areas are flattened onto a solid background. It is a still-image format (no animation).
Can browsers open NEF files directly?+
No — browsers can't display NEF in a page. Convert it to JPG or PNG first, which you can do here with nothing uploaded.
How do I open or convert a NEF file for free?+
Drop your NEF file into the EditItAll converter and choose an output format — it decodes and re-encodes entirely in your browser, with nothing uploaded, no account and no watermark. (There is no in-browser NEF encoder, so you can convert NEF to other formats but not save back to NEF.)
