Extract text from Web app manifests (WEBMANIFEST)
To convert WEBMANIFEST Manifests to another format, you need Visual Studio Code or other Web software.
To convert other file formats to the "Web App Manifest" file type, you need software like Visual Studio Code or a similar tool.
The .WEBMANIFEST file is a configuration document used by developers to build Progressive Web Apps (PWAs). It contains essential metadata - such as the app name, icons, start URL, and display preferences - that tells a web browser how the app should look and behave when installed on a user's desktop or mobile device.
These files are plain text structured in the JSON format. You can easily open and edit them using standard code editors like Visual Studio Code or Notepad++.
While crucial for modern web development, the .WEBMANIFEST format has strict limitations. It does not allow comments, making code annotation impossible, and even a single missing comma or unquoted string will break the entire application installation. For non-developers, this file appears as confusing, unformatted code. Furthermore, strict browser caching behavior can make updates frustrating to push to end-users.
To make the data easier to process, parse, or share, users often need to convert .WEBMANIFEST files to standard JSON format. Other common targets include TXT for basic sharing or XML for integration into legacy data systems. Keep in mind that converting to XML changes the internal structure, meaning the file will no longer function as a PWA manifest unless converted back.
Because .WEBMANIFEST is a specialized extension, standard online converters frequently fail to process it. They see an unknown file type and block the upload. Just drag and drop your file to identify the format, view it, and convert it when possible on convert.guru. Our system recognizes the underlying JSON structure, allowing you to bypass annoying extension limits and safely read or export the embedded text data.
Convert.Guru analyzes your WEBMANIFEST file, detects the exact format, and lets you read the text inside.
Users also converted MANIFEST, HTML, PW_600, CFF2 and HT_ files.
If you want to convert WEBMANIFEST file to HTML, HTM, CSS, JS, PHP, ASP, ASPX, JSP, JSPX, PY, RB or PL, you can use Visual Studio Code or similar software from the "PWA Configuration Metadata" category. In the File menu, look for Save As… or Export….
To convert RSS, CSS, CGI, SITEMAP, PL, JSON, JS, XML, HTML, ICO, HTM or RB files to WEBMANIFEST, try Visual Studio Code or another comparable tool in the "PWA Configuration Metadata" 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 WEBMANIFEST converter.
