Convert Nikon NEF to TIFF — in your browser, no upload

Turn Nikon NEF RAW files into TIFF — lossless archival master — all at once. Files never leave your device; everything is decoded right here in your browser. No sign-up, no watermark, no limits.

What is an NEF file?

NEF (Nikon Electronic Format) is Nikon's RAW format, written by Z-series mirrorless and D-series DSLRs and stored in a TIFF-based container. Each NEF holds the sensor's unprocessed data — at 12 or 14 bits, compressed or uncompressed depending on your camera settings — along with an embedded JPEG preview. That raw data carries far more tonal range than a finished image, which is exactly why everyday viewers, browsers and chat apps can't display a NEF until it's converted.

What is TIFF, and why convert NEF to it?

TIFF is a lossless, high-fidelity image container long used in photography, printing and archiving. It stores the full developed image without compression artifacts and is the format many editing and print workflows expect as a master file. TIFFs are large, but they preserve every detail of the conversion.

Convert Nikon NEF to TIFF when you need an archival-quality master — for print, for handing into a professional editing pipeline (Photoshop, Affinity, print RIPs), or for long-term storage of the developed image outside the proprietary RAW. Pixadel decodes the NEF fully and writes an uncompressed TIFF, so nothing is thrown away. Expect the largest file of any output here; for sharing or the web, choose JPG instead.

Why convert NEF with Pixadel

Nikon's NX Studio is capable but bulky to install and slow to launch for a quick job. Pixadel is built for the "just give me the JPGs" moment: drop a folder of NEFs, get a ZIP back, all processed locally with nothing uploaded. There's no account to create and no per-file limit — handy when you've shot hundreds of frames and only need shareable copies.

How NEF → TIFF conversion works

Every NEF is demosaiced with the camera's recorded white balance and rendered into sRGB before encoding, so the JPG looks like the camera's own output rather than a flat raw dump. You set the quality (default 92) and can export at half size for speed. Pixadel handles the common NEF compression variants automatically; if a scan or unusual file can't be fully developed, it falls back to the embedded preview so you still get a usable image instead of an error.

Frequently asked questions

Why convert NEF to TIFF instead of keeping the RAW?
The NEF is a proprietary RAW that many editors and print shops can't open directly. A TIFF is a developed, standardized, lossless master that any professional tool accepts — useful when you need to hand the image off while keeping full quality.
Is the TIFF compressed?
Pixadel writes an uncompressed TIFF for maximum compatibility and fidelity, so files are large. If you need a smaller lossless file, PNG is usually more compact; for sharing, use JPG.
Can I convert hundreds of NEF files at once?
Yes — Pixadel queues the whole folder and runs a worker pool, then bundles the JPGs into one ZIP. There’s no cap.
Does converting reduce quality?
You choose the JPEG quality (default 92). The NEF is fully demosaiced with the camera-recorded white balance before encoding, matching the camera’s output.
Are NEF files uploaded to a server?
No. Everything runs in your browser via libraw compiled to WebAssembly — refresh and the files are gone.
Does it handle both Z and D series, and NRW?
Yes — Z-series mirrorless and D-series DSLR NEFs both work, plus NRW from compact Nikons in most cases. Drop them in and Pixadel detects the variant.
