How to do it, step by step
- Select the WebM file.
- Choose the bitrate and channels, if needed.
- Click Extract audio.
- Listen in the player and download the MP3.
When this is useful
Keep the sound of a recording made in the browser
Screen and meeting recordings usually come out as WebM.
Use the audio in a program that does not open WebM
MP3 is accepted by most devices and programs.
Tips for a good result
- For a voice recording, mono at 128k keeps the file small.
- To record the screen first, use WebFaz Screen Recorder.
What this tool does not do
- MP3 is a lossy format: the quality never exceeds that of the audio that was in the video.
- One video at a time, and the extraction depends on the device’s memory: very large videos may fail.
- The video must have an audio track; if it does not, the app warns you.
- The new file carries the “WebFaz.com” credit in the metadata (comment and artist).
Frequently asked questions
- Is the WebM’s audio re-encoded?
- Yes. The sound is converted to MP3, which is why the chosen bitrate applies to the new file.
