Upload your MOV 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 MOV 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.
Yes, within the free size limit. PRO supports much larger MOV files and parallel batch extraction.
Does PDF.to read or store my MOV content?
+
No. The MOV video and the WAV audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple MOV files?
+
Yes — drop a folder of MOV 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 MOV container metadata when available. You can edit them after extraction with our audio-tag tool.
转换器是否对流视频 URL 工作?
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the MOV legally first, then upload it for WAV extraction.
Why is the WAV file much smaller than the MOV 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.
