Convert SWF to OGV — Free Online Converter

SWF (Shockwave Flash) is Adobe's discontinued multimedia format. OGV (Ogg Video) is an open-source video container using the Theora video codec and Vorbis audio codec, developed by the Xiph.Org Foundation as a royalty-free alternative to patent-encumbered formats like H.264/MP4. Converting SWF to OGV preserves Flash content in an entirely open, patent-free video format.

OGV was a significant format in the early HTML5 video era, championed by Firefox and Wikipedia as a DRM-free, patent-free video standard. While VP9/AV1 have largely succeeded Theora for new encoding, OGV remains important for organizations committed to using only patent-free technology and for legacy web applications built around the Ogg ecosystem.

OGV is the only widely-deployed video format that is completely free of patent claims and licensing fees. For organizations, governments, and projects that require patent-free media — including Wikipedia, Wikimedia Commons, and many open-source projects — OGV is the standard video format. Converting Flash content to OGV aligns with open media principles.

OGV is also supported natively by Firefox without any proprietary codec dependencies. For web applications that serve video to Firefox users and want to avoid relying on platform-specific H.264 decoders, OGV provides a guaranteed open-source playback path.
