Should you convert VOB to MP3?
Yes, when you only need the sound: a song from a music video, the audio of a lecture, or a voice recording to transcribe. The picture is left out and the soundtrack is saved as MP3.
VOB is the MPEG-2 video files inside a DVD’s VIDEO_TS folder; MP3 is the most compatible lossy audio format ever made. Use MP3 when you don’t know what will play the file: cars, old players, podcasts hosts and upload forms all take it.

How to convert VOB to MP3

Save the MP3
Press convert and save the MP3. Several files come back together as a ZIP.
What changes when VOB becomes MP3
From AC-3 or MP2 to MP3
VOB soundtracks are usually AC-3 or MP2, so saving MP3 is one more lossy step. 192 kbps suits music, 128 kbps is plenty for speech, and going above the original bitrate only makes the file bigger.
Video files without sound
Screen recordings and some exported clips have no audio track at all. The file is checked as soon as you add it, and you’ll be told before converting if there’s nothing to extract.
This page is put together from our notes on each format, choosing only what is true of VOB and MP3, so every pairing states the same facts the same way. How these pages are made.
Why it doesn’t upload
Uploading a whole video to keep only its sound wastes time and data, and hands over the footage too. The audio track is read and saved right here, and the file never leaves your device.
How to check for yourselfWorth knowing
- About the VOB. A film is spread across VTS_01_1.VOB, VTS_01_2.VOB and so on; converting one gives you one chunk of it. Commercial discs are usually copy-protected too.
- About the MP3. Converting a low-bitrate MP3 to 320 kbps makes it bigger without making it sound any better; what was thrown away is gone.
- AVI, WMV, FLV and other older formats use the FFmpeg engine, a one-time 31 MB download.
Questions
Does extracting MP3 from a VOB lose quality?
The soundtrack is compressed again as MP3. At 192 kbps the difference from the original is inaudible for nearly everyone.
Can I get the audio from only part of the video?
Yes. Set a start and end time before converting, and only that section is saved as MP3.
