M4V to M4R Conversion FAQ
How do I extract audio from a M4V video as M4R?
+
Upload your M4V video. PDF.to pulls the audio track out, encodes it to M4R, and gives you a M4R-only download. The video stream is discarded.
Will the M4R 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 M4V to M4R extraction free?
+
Yes, within the free size limit. PRO supports much larger M4V files and parallel batch extraction.
Does PDF.to read or store my M4V content?
+
No. Nobody reads the contents of your M4V, and nothing is shared. The uploaded M4V and the resulting M4R 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 M4V 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 M4V legally first, then upload it for M4R extraction.
Why is the M4R file much smaller than the M4V video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the M4R, which is why it can drop from gigabytes to a few megabytes.
