Why convert WMV to MP3?
WMV files come from Windows Movie Maker, older Windows cameras and corporate video archives. Macs, phones and browsers rarely play WMV. Choose MP3 when the audio must play on any device, car stereo or upload form.
Audio extraction options
Only the audio track of the WMV is processed, so this is much faster than a video conversion. Choose the bitrate or quality, optionally trim to a start and end time, and download the MP3.
Frequently asked questions
Will the MP3 lose quality?
Both formats are lossy, so converting re-encodes the data once more. Using a high quality setting keeps the generational loss very small. Avoid converting the same file back and forth repeatedly.
How big will the MP3 file be?
About 1.4 MB per minute of audio at the default 192 kbps, so a 10-minute WMV gives roughly 14.4 MB. The size of the video track does not matter, because only the sound is kept. Choose 128 kbps for speech to make it about a third smaller.
