Convert M4B to MOV — Free Online Converter

MOV (QuickTime Movie) is Apple's multimedia container, closely related to M4B since both are based on the ISO Base Media File Format. Converting M4B to MOV moves audiobook audio into QuickTime's container, which is the standard working format for Apple's professional tools (Final Cut Pro, Motion, Compressor). The conversion discards M4B's chapter track and bookmark functionality, producing a standard audio-in-video container.

Final Cut Pro and other Apple production tools work with MOV containers. If audiobook narration needs to be part of a video project — documentary, YouTube video, educational content — converting to MOV provides a seamless import. QuickTime Player on macOS also provides editing tools (trim, split) for MOV that are not available for M4B files.
