How do I extract audio from a MP4 video as AMR?

Upload your MP4 video. PDF.to pulls the audio track out, encodes it to AMR, and gives you a AMR-only download. The video stream is discarded.

Will the audio in the AMR match the original MP4 quality?

If the source audio is already in a codec compatible with AMR, 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 AMR output?

192 kbps ny sanda tsotra. Mampiseho ny 96, 128, 192, 256, ary 320 kbps ny tontonana safidy — misafidy ny ambony indrindra ho an'ny mozika, ny ambany indrindra ho an'ny feo.

Can I extract only part of the MP4 as AMR?

Yes. Use the trim controls on the upload preview to set start and end times before extracting, and only that range becomes AMR.

Does the converter handle MP4 files with multiple audio tracks?

Yes. If your MP4 has several language or commentary tracks, you can pick which one(s) to extract as AMR in the options panel.

Will the AMR output have the same sample rate as the source?

Eny araka ny tsotra. Tsy atao ny manova ny santionany raha tsy hoe mangataka izany ianao. Ny 48 kHz no voatahiry amin'ny loharanon-tsary, ny 44.1 kHz kosa amin'ny loharanon-kira.

Is the MP4 to AMR extraction free?

Yes, within the free size limit. PRO supports much larger MP4 files and parallel batch extraction.

Does PDF.to read or store my MP4 content?

No. The MP4 video and the AMR audio output are deleted within an hour. Conversion runs in an isolated worker.

Can I batch-extract audio from multiple MP4 files?

Yes — drop a folder of MP4 videos and you will get a ZIP of AMR files back, one per source video.

Will the AMR preserve tags and metadata?

Title, artist, and album tags are populated from the MP4 container metadata when available. You can edit them after extraction with our audio-tag tool.

Mampiasa URLs mivezivezy ve ilay mpanova?

No — PDF.to converts files you upload, not third-party stream URLs. Download the MP4 legally first, then upload it for AMR extraction.

Why is the AMR file much smaller than the MP4 video?

Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the AMR, which is why it can drop from gigabytes to a few megabytes.
