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