What is it?

File Converter adds conversion and compression commands to the Windows Explorer context menu, so you can process one or several files without opening a separate application. It is aimed at users who want a quick way to change a file's format or reduce its size.

The project bundles several open-source engines behind the scenes: FFmpeg for audio and video, ImageMagick for image editing and conversion, and Ghostscript for PDF handling. It also uses SharpShell to register the Explorer menu extensions and includes CD audio extraction. The interface is a WPF application with localization in many languages.

The project is written in C# for Windows, and the installer is built with WiX. Documentation and downloads are provided on the project website and wiki.
