Supports: NEF (Nikon RAW)
RAW support varies by camera and file. The decoder may fall back to the embedded preview, so output resolution can be lower than the sensor data.
How to Convert NEF to JPG
Vizua is a free NEF to JPG converter that uses an advanced RAW decoder directly in your browser. NEF (Nikon Electronic Format) stores unprocessed sensor data from Nikon cameras — perfect for editing but impractical for sharing online.
Converting NEF to JPG reduces file size by 80-95% and makes your Nikon photos compatible with any device, social media platform, or messaging app.
Why NEF Files Need Converting
A single NEF file from a Nikon D850 can be 45-50 MB at full resolution. Web browsers, email clients, and social media platforms don't support NEF natively. JPG is the universally accepted format for photo sharing and everyday use.
Nikon Cameras That Use NEF
- Professional — D850, D6, Z8, Z9
- Enthusiast — D750, D780, Z5, Z6, Z7 (and Mark II variants)
- Entry-level — D3500, D5600, D7500, Z30, Z50, Zf, Zfc
- Legacy — D700, D300, D90, and older Nikon DSLRs back to the D1
Quality Control
The quality slider controls JPEG encoding after decoding. NEF conversion may use the embedded preview, so higher JPEG quality cannot restore sensor detail or resolution absent from that preview.
Local File Processing
The selected NEF file is decoded and exported on your device rather than uploaded to an image-processing server. Compatibility and output resolution vary by camera file and embedded preview.

Can I convert multiple NEF files at once?
Yes — drop several NEF files and download each JPG individually or as a ZIP archive.
