About RNG files

The .RNG extension represents a collision between legacy mobile history and modern XML development, creating significant confusion for users. Most commonly, these are Nokia Composer Ringtones, a proprietary monophonic audio format used on early 2000s Nokia cell phones. These files are essentially text-based instructions for a phone's buzzer and are largely incompatible with modern media players like VLC or smartphones, requiring conversion to MP3 or MIDI for preservation or playback.

Alternatively, an .RNG file is often a RELAX NG Schema, a grammar used to validate XML documents. While RELAX NG is praised by developers for its simplicity compared to W3C XML Schema, it suffers from limited support in enterprise tooling. Developers frequently need to convert these schemas to XSD or DTD formats to ensure compatibility with stricter validation pipelines or specific IDEs like Microsoft Visual Studio. Less frequently, this extension may hold PokerTracker hand ranges or Allplan engineering data. Because these formats are binary-incompatible, simply attempting to open an .RNG file often results in errors. You can use convert.guru to instantly identify the file structure - whether it contains audio data or XML tags - and convert it to a usable format like MP3, XSD, or PDF.

Use Convert.Guru to open and convert your RNG file.

Users also converted JPG, NRG, MP3, PNG, XPT, CXL, CLIENT, XSD and SGD files.

The RNG Converter Story

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 RNG converter.
