What is OGV to FLV conversion?

Ogg Video (OGV) and Flash Video (FLV) are two popular video containers, but not every player or editor handles them all. This free converter reads your .ogv file, decodes its streams and re-encodes them into a valid .flv file with widely supported codecs. The whole conversion runs in your browser, so your video stays private.

How it works

1Upload a .ogv video file.
2Choose FLV from the output format menu.
3Click Download — the video is re-encoded locally in your browser.
4Save the converted .flv file. No signup needed.
