How to Convert Files

Convert OGV Ogg video to and from common formats in your browser, with all processing done locally on your device.

What an OGV file holds

OGV is video in the Ogg container, the open, royalty-free multimedia format from the Xiph.Org Foundation. The .ogv extension specifically denotes an Ogg file carrying video, typically encoded with the Theora video codec and Vorbis or Opus audio.

Ogg was created as a fully open alternative to patent-encumbered formats, and OGV brought that philosophy to web video. Theora, its usual video codec, provides reasonable compression without licensing costs, which made OGV one of the free formats supported when HTML5 video first arrived.

Strengths and limits

OGV's strength is openness: it is fully royalty-free and supported by open-source software and standards-based browsers, making it a safe choice where licensing freedom matters.

Its usual Theora codec is less efficient than H.264, and far less than modern codecs like AV1, so files are larger for the same quality. Adoption has been modest, and WebM with VP9 or AV1 has become the preferred open web video format.

OGV Development History

OGV was developed by the Xiph.Org Foundation in the early 2000s as part of a broader initiative to create open multimedia formats. The Theora video codec, which is commonly used with OGV, was derived from the VP3 codec acquired by Xiph in 2001. OGV addressed the need for a royalty-free video format that could be used for web streaming without licensing concerns. This was particularly important as proprietary formats dominated the market.

As web standards evolved, OGV gained traction among open-source communities and developers focused on web technologies. The format was integrated into various media players and web browsers, promoting its use in HTML5 video elements. The establishment of the Ogg container format allowed for a flexible structure, accommodating different audio codecs alongside video. Over time, OGV became a staple for projects emphasizing open standards, contributing to its adoption in educational and non-profit sectors.

Using OGV Effectively

Choose OGV when licensing freedom is paramount, particularly for projects that prioritize open-source software. It is ideal for web applications where compatibility with various browsers is required. OGV is often used in educational content, independent films, and user-generated content platforms. However, consider the target audience's playback capabilities, as some older devices may not support OGV natively.

When converting to or from OGV, ensure that the video codec used is Theora, as it is the most compatible. Use tools like FFmpeg for conversions, as it supports a wide range of formats and codecs. Be aware of audio codec compatibility; Vorbis is commonly used but Opus can also be employed for better quality. Always test playback in multiple browsers to avoid compatibility issues, particularly with older versions that may not fully support OGV.

Working with OGV files

You will meet OGV in open-source projects, older HTML5 video, and content from communities that prioritise royalty-free formats.

For broad compatibility or smaller files, convert OGV to H.264 in an MP4, or to WebM if you want to stay with an open format while improving efficiency over Theora.
