Convert MOV to OGG — Free Online Converter

MOV files from Apple devices contain audio in AAC or ALAC alongside video. OGG is Xiph.org's open-source multimedia container, most commonly holding Vorbis audio — a free alternative to MP3 and AAC. Developed by Christopher Montgomery starting in 1993, Vorbis delivers quality comparable to AAC at similar bitrates while being completely royalty-free and open-source.

OGG Vorbis is the preferred audio format in open-source software, Linux distributions, and game engines (Unity, Unreal Engine, Godot use OGG for game audio). Extracting audio from MOV to OGG produces files compatible with these ecosystems without any proprietary codec dependencies.

Spotify uses OGG Vorbis as its streaming format, and Firefox historically preferred OGG for HTML5 audio. The format remains deeply embedded in the open-source world.

FFmpeg extracts the audio from the MOV container, decodes AAC/ALAC to PCM, and encodes to Vorbis using libvorbis, wrapped in the OGG container. Quality is controlled by the -q:a flag (0-10 scale, where 5 is roughly 160 kbps VBR). The OGG container uses a page-based structure with Ogg framing that supports seeking and streaming. Vorbis comment metadata is supported for tags.
