About CNG files
A .cng file is a CryptoNG Encrypted Archive created by the CryptoNG software, developed by Vassil Arabadjiev. It is used to bundle multiple files into a single compressed and encrypted package for secure local storage or transmission. Because this format is proprietary and specifically designed to lock away data, it carries severe usability disadvantages. You cannot open it natively on standard operating systems like Windows or macOS. It strictly requires the original CryptoNG software and the exact user password to extract the contents. Without these, popular standard archive managers like 7-Zip or WinRAR cannot open, mount, or read the file. Standard online converters fail to process .cng files because they lack the decryption key and do not support this obscure, closed-source format. If you have the password, your best option is to extract the contents locally and then repackage them into a standard, universally accessible format like ZIP or 7Z. Despite these strict encryption limitations, our platform can still help you analyze the file. Our engine will inspect the file headers to verify if the archive is structurally intact or corrupted, giving you valuable metadata even if the encrypted payload remains securely locked.
Convert.Guru analyzes your CNG file, detects the exact format, and lets you read the text inside.
If you want to convert CNG file to JPG, LPG, LNG, PDF, BASE64, HEX, BIN, ENC, CRYPT, AES, DES or RSA, you can use CryptoNG or similar software from the "Encrypted Data Archiving" category. In the File menu, look for Save As… or Export….

The CNG 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 CNG converter.
