3GP to WAV Conversion FAQ
How do I extract audio from a 3GP video as WAV?
+
Upload your 3GP 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 3GP to WAV extraction free?
+
Yes, within the free size limit. PRO supports much larger 3GP files and parallel batch extraction.
Does PDF.to read or store my 3GP content?
+
No. Nobody reads the contents of your 3GP, and nothing is shared. The uploaded 3GP 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 3GP 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 3GP legally first, then upload it for WAV extraction.
Why is the WAV file much smaller than the 3GP 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.
