Convert AIFC to OGV — Free Online Converter

AIFC (AIFF-C) is Apple's compressed audio interchange format from the late 1980s, a legacy container found almost exclusively in classic Mac OS and NeXTSTEP archives. OGV (Ogg Video) is an open-source multimedia container from the Xiph.org Foundation, designed for web video delivery using the Theora video codec and Vorbis audio codec — both completely patent-free.

Converting AIFC to OGV produces an audio-only OGV file — the audio is encoded as Vorbis and wrapped in the Ogg container with the .ogv extension. This is relevant for open-content platforms like Wikimedia Commons, which historically preferred OGV for all media content, and for legacy web deployments that used OGV before HTML5 video settled on MP4 and WebM.

Wikimedia Commons and other open-content platforms historically required OGV (or WebM) for all uploaded media, including audio-only content. AIFC is not accepted by any open-content platform. Converting AIFC to OGV makes legacy Mac audio compatible with these platforms' patent-free media requirements.

OGV also serves legacy web applications that were built around the Ogg container before WebM became the dominant open format. Some institutional and educational web systems deployed Ogg-based media infrastructure that remains operational. AIFC cannot be used in any of these systems.
