Convert OGV to MP3
Ethical Tube's free OGV to MP3 converter saves the soundtrack of OGV videos as MP3, the most compatible audio format. It runs entirely in your browser, so your videos are never uploaded, and it's free with no sign-up or watermark. The first conversion downloads the FFmpeg engine (10 MB) once, and it's cached after that.
Files are converted on your device and never uploaded.

The formats
OGV and MP3 at a glance
What is an OGV file?
OGV is video in the open Ogg container, usually Theora video with Vorbis audio. It was common on Wikipedia and in open-source projects, but Theora is old and inefficient. Chrome has dropped Theora playback, and Safari and iPhone never supported it. It opens in Firefox, VLC, mpv, and editors like Shotcut and Kdenlive. Chrome, Safari, QuickTime, and iPhone can't play it.
What is an MP3 file?
MP3 is the most widely supported audio format. Its lossy compression makes files about a tenth the size of CD audio, and at 192 kbps or more most people can't hear the difference. Every device that plays music plays MP3. It opens in everything: phones, computers, car stereos, smart speakers, browsers, and every music player and audio editor.
Good to know
What changes when you convert OGV to MP3
- Only the soundtrack is saved; the picture is dropped.
- The audio is saved as MP3 at 192 kbps (you can pick 128 to 320 kbps).
- If the video's audio is already MP3, it's copied without re-encoding, so there's no quality loss. Picking a bitrate re-encodes it at that bitrate instead.
- OGV files are read with FFmpeg running in your browser.
- The first conversion downloads FFmpeg compiled to WebAssembly (10 MB). It's cached, so later visits start quickly.
- Copy-protected (DRM) files can't be converted.
- Very long videos can run out of memory, especially on phones.
FAQ
Questions, answered
Is this OGV to MP3 converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with FFmpeg compiled to WebAssembly, so your files never leave your device. Once the page and the engine have loaded, it even works offline.
Does converting OGV to MP3 lose quality?
MP3 is a lossy format, so the audio is compressed. At the default bitrate most people can't hear a difference. Choose 256 or 320 kbps for music you care about.
How long does it take?
When the video can be copied without re-encoding, a few seconds. Otherwise it depends on the video's length and resolution and on your device. With a hardware encoder, a 10-minute 1080p video usually takes a few minutes on a laptop.
Can I convert several OGV files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each MP3 file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
Yes, in any current browser on a computer or phone. FFmpeg runs on your processor without hardware acceleration, so long videos are much faster on a computer.
What can open an MP3 file?
Everything: phones, computers, car stereos, smart speakers, browsers, and every music player and audio editor.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and a computer can usually handle videos up to about 2 GB.
