Extract text from Windows installers (WIN64)
To convert WIN64 installers to another format, you need NW.js or other Developer software.
To convert other file formats to the "Build Artifact" file type, you need software like NW.js or a similar tool.
The .win64 extension is a non-standard suffix used by developers to label build artifacts for Windows 64-bit systems. It is not a registered file format but a naming convention that causes significant confusion because Windows cannot natively open it.
Most commonly (65%), these files are ZIP archives generated by NW.js (Node-Webkit) build tools. These contain the application's source code, assets, and the package.json file required to run the app. Users often encounter these when downloading open-source software or developer tools.
Less frequently (20%), the extension appears on application installers, such as those for Postman, where the file is actually a standard Windows Executable (EXE). In these cases, the file works perfectly but lacks the correct .exe extension to trigger the installation wizard.

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 WIN64 converter.
