Convert raw image files (NRW) online for free
The converter easily converts your NRW raw files to various formats - free and online. No NX Studio or or other Camera Raw software needed.
To convert other file formats to the "Proprietary Sensor Data" file type, you need software like NX Studio or a similar tool.
The .NRW extension primarily indicates a Nikon Raw Image generated by high-end COOLPIX cameras (such as the P1000, P950, or B700). Unlike Nikon's ubiquitous NEF format used in DSLRs, .NRW files are specific to their bridge/compact line but still contain massive, uncompressed 12-bit sensor data. While this preserves maximum detail for editing, it can lead to major headaches: files often exceed 20MB, they appear "flat" or dark without processing, and they trigger the "Windows cannot open this file" error unless you install the specific Raw Image Extension or NX Studio.
A secondary, legacy use case involves Nokia mobile phones (Series 40/Symbian era). These .NRW files are often "glitched" temporary files that failed to process into JPEGs inside the phone. For these, standard viewers will fail completely.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NRW converter.
