Quick answer: To extract OGG audio from FLV video, add the FLV file to the iHateFiles FLV to OGG converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. Lifts the soundtrack out of the video and saves it as OGG. The picture is discarded; nothing is re-recorded.
Should you convert FLV to OGG?
Worth doing when you want the soundtrack of a FLV on its own: a podcast, an interview, a piece of music from a video. Choose a higher bitrate than you think you need, because the OGG is encoded from the video's audio rather than from a master.
Taking the sound out of FLV
A FLV file holds a picture track and a sound track side by side. This keeps the sound and discards the picture, so what you get is the OGG on its own at whatever bitrate you choose. Nothing about the FLV original is altered.

What usually goes wrong
About the FLV. If you have FLV files they are probably old downloads worth rescuing, and converting them to MP4 is the way to keep them watchable.
About the OGG. Ogg is the container, Vorbis is the codec, and an .ogg file can also contain Opus or FLAC. That is why one .ogg plays somewhere another will not.
How to convert FLV to OGG
- Add your FLV file. It is read from your disk and stays there.
- Check the settings. The output format is already set to OGG.
- Press convert and the OGG file is saved back to your device.
Questions
How do I convert FLV to OGG?
Open this page, add your FLV file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this FLV to OGG converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Does extracting audio reduce the quality?
The soundtrack is re-encoded to OGG, so there is one generation of loss at the bitrate you choose. Pick a higher bitrate, or a lossless target like WAV or FLAC, to avoid it.
Can I convert several FLV files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
