VOB to WAV Conversion FAQ
How do I extract audio from a VOB video as WAV?
+
Upload your VOB video. PDF.to pulls the audio track out, encodes it to WAV, and gives you a WAV-only download. The video stream is discarded.
Will the WAV output have the same sample rate as the source?
+
Yes by default. We do not resample unless you explicitly request it. 48 kHz is preserved from movie sources, 44.1 kHz from music sources.
Is the VOB to WAV extraction free?
+
Yes, within the free size limit. PRO supports much larger VOB files and parallel batch extraction.
Does PDF.to read or store my VOB content?
+
No. Nobody reads the contents of your VOB, and nothing is shared. The uploaded VOB and the resulting WAV are deleted from our servers automatically about 24 hours after the conversion, which leaves time to download the result.
Can I batch-extract audio from multiple VOB files?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Does the converter work on streaming video URLs?
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the VOB legally first, then upload it for WAV extraction.
Why is the WAV file much smaller than the VOB video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the WAV, which is why it can drop from gigabytes to a few megabytes.
