About RND files
A .RND file typically functions as a proprietary Sound Level Meter Data file created by acoustic devices from Rion Co., Ltd or Cirrus Research. Alternatively, the extension is used for Rendered CAD Drawings exported by Bentley MicroStation, cryptographic Random Seed files used by PGP or OpenSSL, or gameplay demos from the 2D shooter Soldat.
The fragmented nature of the .RND extension causes major compatibility issues. If you receive an acoustic .RND file, it is locked in a proprietary format that requires specific, often expensive, analysis software like NoiseTools to read. Sharing this raw data with clients is impossible without exporting it first. If the file is a MicroStation CAD render, it is actually a TIFF image disguised by a custom extension, which causes standard image viewers to reject it outright. Cryptographic seed files are system-level binary files that look like gibberish if opened in a text editor.
To make this data usable, conversion is necessary. Convert acoustic .RND data to CSV or XLSX for spreadsheet analysis, or to PDF for archival reporting. For MicroStation renders, convert to TIFF, PNG, or WebP for broad web and print compatibility. Drag and drop your file here to analyze and convert it - free, online, and without installing software.
Convert.Guru analyzes your RND file, detects the exact format, and lets you read the text inside.
Users also converted RND-DATA, RMD, SHF, AEXPK and BEXPK files.

The RND 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 RND converter.
