VB.NET supports dynamically loading dll files at runtime and using class and procedures from them. The trick is to create an "interface" and use that:

Public Interface IPlugin
    Sub Run()
End Interface

Public Sub RunPlugin(byval vPlugin as IPlugin)
    vPlugin.Run
End Sub

Public Class MyPlugin
    Implements IPlugin
    Public Sub Run() Implements IPlugin.Run
        ' Do something
    End Sub
End Class

Then you would just make dll files for all your format converters and store them in a folder with your app. Use System.Reflection.Assembly.LoadFrom() to grab a list of dll files in a certain path.

Do a search for "vb.net plugin" to see lots of examples. Good luck! ;-)
