Extract text from NRB files
To convert your NRB file to another format, you need NetEase Interactive Whiteboard or other Data software.
To convert other file formats to the "Session Recording Log" file type, you need software like NetEase Interactive Whiteboard or a similar tool.
The .NRB extension is shared by two distinct formats, leading to frequent compatibility errors. The most common modern variant (approx. 48%) is an Interactive Whiteboard Recording created by NetEase Interactive Whiteboard. Internally, this file is a structured JSON document that logs vector strokes, timestamps, and event data to 'replay' a drawing session. Because it is a data log rather than a video file, it cannot be opened by standard media players like VLC or QuickTime. Users generally convert these .NRB files to MP4 or WebM for universal playback, or to PDF to capture the final static image of the board.
Alternatively, older .NRB files may be Nero CD-ROM Boot Compilations created by Nero Burning ROM. These are proprietary binary configuration files used to structure bootable optical discs. They are useless outside the Nero ecosystem and are often flagged as 'unknown' by modern operating systems. To access the data or archive these legacy projects, users typically convert them to the industry-standard ISO format, which can be mounted on Windows/macOS or used in virtualization tools like VirtualBox.
Convert.Guru analyzes your NRB file, detects the exact format, and lets you read the text inside.
Users also converted UDF, NRG and IMA files.

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 NRB converter.
