Convert M4B to WMV — Free Online Converter

WMV (Windows Media Video) is Microsoft's video container. Converting M4B audiobooks to WMV wraps narration inside a video container with WMA audio encoding and optionally a static cover image as a video track. This legacy conversion targets enterprise Windows environments — corporate training systems, digital signage, and LMS platforms from the Windows Media era that only accept WMV multimedia files.

Corporate training platforms built on Windows Media technology may only accept WMV uploads. Enterprise LMS (Learning Management Systems) from the early 2000s often use WMV as their sole multimedia format. Digital signage systems in corporate lobbies and training rooms may require WMV for audio content display. Converting M4B audiobooks to WMV with a book cover as the video creates a 'video' suitable for these systems.
