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 audio in the WAV match the original 3GP quality?
+
If the source audio is already in a codec compatible with WAV, we stream-copy without re-encoding — bit-identical to the original. Otherwise we re-encode at 192 kbps by default for near-transparent quality.
What bitrate is the WAV output?
+
192 kbps by default. The options panel exposes 96, 128, 192, 256, and 320 kbps — pick higher for music, lower for voice.
Can I extract only part of the 3GP as WAV?
+
Yes. Use the trim controls on the upload preview to set start and end times before extracting, and only that range becomes WAV.
Does the converter handle 3GP files with multiple audio tracks?
+
Yes. If your 3GP has several language or commentary tracks, you can pick which one(s) to extract as WAV in the options panel.
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 for files under 100 MB. PRO supports larger 3GP files (5 GB) and parallel batch extraction.
Does PDF.to read or store my 3GP content?
+
No. The 3GP video and the WAV audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple 3GP files?
+
Yes — drop a folder of 3GP videos and you will get a ZIP of WAV files back, one per source video.
Will the WAV preserve tags and metadata?
+
Title, artist, and album tags are populated from the 3GP container metadata when available. You can edit them after extraction with our audio-tag tool.
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.
