Quick answer: To extract OGG audio from MP4 video, add the MP4 file to the iHateFiles MP4 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 MP4 to OGG?
Worth doing when you want the soundtrack of an MP4 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 MP4
An MP4 file holds H.264 or H.265 video with AAC sound. This keeps the sound, discards the picture, and writes the result as OGG (Vorbis). The MP4 original is not altered.
One more generation of compression
The sound inside an MP4 is almost always compressed already. Re-encoding it as OGG compresses it again, so set the bitrate at or above the original. For music, 192 kbps or more is a safe floor; for speech, far less is fine.
MP4 and OGG side by side
| MP4 | OGG | |

| Inside the file | H.264 or H.265 video with AAC sound | Vorbis |
| Compression | Lossy | Lossy |
| Carries sound | Yes | Yes |
| Plays on | every phone, laptop, TV, browser and messaging app | Android, Firefox, Chrome and games, but not Apple Music or older players |

What usually goes wrong
About the MP4. Two MP4 files can behave completely differently depending on the codecs inside. A file that will not play is usually an unusual codec in an ordinary container, not a broken file.
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 MP4 to OGG
- Add your MP4 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 MP4 to OGG?
Open this page, add your MP4 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 MP4 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 MP4 files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
