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