About VOB to MP3 conversion
VOB is a DVD-Video disc container format introduced in 1996, which encapsulates MPEG-2 video and AC-3/LPCM/DTS audio tracks, with a single file often exceeding 1GB. MP3 is a lossy audio encoding format standardized in 1993, all its patents expired in 2017, and it is compatible with all devices. Extracting DVD audio tracks requires conversion to MP3.
This conversion extracts the embedded audio track from VOB and re-encodes it to MP3. The output bitrate can be manually adjusted between 64kbps and 320kbps. It preserves the original number of audio channels and base sample rate, retains original audio track metadata and writes it to ID3 tags. High bitrate output delivers audio quality closer to the original source.
The output MP3 can be played directly on Windows, macOS, Linux desktop systems, and iOS, Android mobile devices. It is suitable for extracting dubbing and song tracks from DVD discs for portable local listening. Single files must comply with this site's 50MB size limit.

FAQ about VOB → MP3
Will there be audio quality loss after conversion?
MP3 is a lossy encoding, so audio quality loss occurs after conversion. Selecting a higher output bitrate reduces the degree of quality loss. At 320kbps, the audible loss is not easily noticeable for general users.
Will original audio metadata be preserved?
This tool preserves the basic metadata of the embedded audio track in VOB, and writes it to the ID3 tag of the output MP3, allowing playback software to recognize and display track information correctly.
What is the maximum single file size supported?
This site sets a 50MB upper limit for single file conversion. Files exceeding this size cannot be submitted for conversion, and only one file can be processed per conversion.
Are uploaded files stored?
Files are uploaded to the server via HTTPS for conversion. After conversion completes, the server immediately deletes both the source file and output file, and does not store any files.
