About Ogg Video

Ogg Video (OGV) is the open Ogg container from the Xiph.Org Foundation holding Theora video, usually with Vorbis audio.

Open-source projects and Wikimedia Commons, which accepts video only in free formats.

Theora compresses less efficiently than modern codecs, and Apple devices do not play OGV natively.

Convert Ogg Video to WebM online free, no account required — WebM is an open, royalty-free web video format with VP8, VP9 or AV1 video and Opus or Vorbis audio.

Why won't my video editor or iPhone open my OGV file? The Theora-based format never left the browser world, so most hardware and software can't decode it — converting to MP4 or WebM makes it playable.

About WebM

WebM is an open, royalty-free video format developed by Google and based on the Matroska container. It holds VP8, VP9 or AV1 video with Vorbis or Opus audio.

It is made for the web: all major browsers play it in the HTML video element, and it is common for screen recordings and short clips.

WebM allows only its own small set of codecs, so H.264 video or AAC audio has to be re-encoded to fit.

Why convert video to WebM for a website? Browsers play it without plugins, and VP9 or AV1 compresses smaller than H.264 at the same quality, so pages load faster.
