Convert WebM to OGV — Free Online Converter

WebM and OGV represent two generations of open-source web video. WebM uses VP8/VP9/AV1 video with Vorbis/Opus audio, while OGV uses the older Theora video codec with Vorbis audio. Both are royalty-free and open-source, but WebM is the modern successor with dramatically better compression.

Converting from WebM to OGV is unusual since OGV is the older, less efficient format. The primary reason is platform requirements — some systems (notably older Wikimedia Commons workflows) specifically require OGV format. Academic and archival platforms built around the original HTML5 open-source video standard may also mandate OGV.

For any other purpose, WebM should be preferred over OGV.
