What’s MConverter.exe (Microsoft Edge PWA Launcher)? Is it safe or a virus?

MConverter.exe is a software program developed by Microsoft Corporation that's used to run Progressive Web Apps on Windows PCs.

A Progressive Web App (PWA) for Microsoft Windows is a type of application software delivered through the web, built using common web technologies including HTML, CSS, and JavaScript. It is intended to work on any platform that uses a standards-compliant browser, including Windows.

The key feature of a PWA is its ability to provide a user experience that is comparable to that of native applications on desktop and mobile devices. This includes the ability to work offline, receive push notifications, and access hardware features, while still being lightweight and efficient.

For Windows users, PWAs can be installed directly onto their devices through the Microsoft Edge browser or the Microsoft Store, allowing these web apps to benefit from deeper integration with the Windows operating system.

This includes functionalities like automatic updates, background tasks, and the ability to pin apps to the Start Menu or taskbar, providing a seamless and engaging user experience. Through the use of service workers and web app manifests, PWAs on Windows can load quickly, even on flaky networks, offer a full-screen experience, and re-engage users with web push notifications, making them an increasingly popular choice for developers and organizations aiming to reach their audience across platforms with minimal effort.
