NEF to HEIC can't be done in your browser
Creating a HEIC file needs an HEVC encoder, which no web browser includes and which can't run privately on your device the way our other conversions do. Reading HEIC works in the browser — writing it doesn't — so an honest, no-upload HEIC converter isn't possible today.
AVIF delivers the same roughly 50% size saving as HEIC, with far wider support — and it converts instantly, right in your browser.
Why convert NEF to HEIC?
HEIC is Apple's photo format, built on the modern HEVC codec — but creating a HEIC file needs an HEVC encoder, and no web browser includes one. Reading HEIC works in-browser; writing it doesn't, so a private, no-upload HEIC converter simply isn't possible today. AVIF gives you the same kind of modern, efficient compression for your decoded NEF, fully supported on the web, and converts instantly right here.
NEF vs HEIC at a glance
NEF is Nikon's RAW format — every photographic detail the sensor captured, before any in-camera processing, editable but unreadable by most everyday software. HEIC is Apple's default photo format — roughly half the size of JPG at the same quality, but barely supported outside Apple devices.

NEF to HEIC — frequently asked questions
Why can't I convert NEF to HEIC here?
Making a HEIC file requires an HEVC encoder, which no web browser provides and which can't run privately on your device the way our other conversions do. We only build converters that work entirely in your browser with no upload — an honest in-browser HEIC encoder isn't one of them.
What should I use instead of HEIC?
AVIF. It uses the modern AV1 codec to reach a similarly small file size for your RAW photo, while being fully supported across browsers and the web. Convert NEF to AVIF instantly here.
