Extract text from NapsternetV config files (NPV4)
To convert NPV4 configs to another format, you need NapsternetV or other Settings software.
To convert other file formats to the "VPN Client Configuration" file type, you need software like NapsternetV or a similar tool.
The .NPV4 file extension is exclusively used as a VPN configuration file by the NapsternetV mobile client. These files store proxy connection credentials, routing rules, and payloads required to route traffic through V2Ray, Xray, Psiphon, or SSH protocols. The primary disadvantage of the .NPV4 format is its strictly proprietary nature. It functions as a closed container, deliberately obfuscated or encrypted to prevent users from sharing the raw server details or tampering with the injected payloads.
Users typically want to convert .NPV4 files to standard JSON or plain TXT to extract the underlying vmess://, vless://, or trojan:// links. This extraction is highly desired so the VPN profile can be reused on desktop environments using clients like v2rayN. However, standard online file converters fail to process .NPV4 files because they lack the specific decryption algorithms required to parse the proprietary data structure.
Because this file format is difficult to open or convert, often only the original NapsternetV software can properly read or execute the profile data. Our engine will analyze the binary structure, strip away the unreadable layers, and reveal any plaintext strings or embedded links. If our analysis detects a supported underlying format, viewing or partial conversion may still be possible.
Convert.Guru analyzes your NPV4 file, detects the exact format, and lets you read the text inside.
Users also converted NPV, NPV2, INPV and NPV3 files.
If you want to convert NPV4 file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use NapsternetV or similar software from the "VPN Configuration Storage" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to NPV4, try NapsternetV or another comparable tool in the "VPN Configuration Storage" category.
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 NPV4 converter.
