WebM to MP3 converter.
Save the audio from any .webm clip as a clean MP3 that plays on any phone or player.

WebM · processed privately, never uploaded
Have a lecture, download, or music video stuck in .webm? This pulls its audio into a standard MP3, the full recording at its original volume, ready for the apps and devices that quietly refuse to open WebM. No account, no watermark, and nothing is uploaded.
Why turn a WebM into an MP3 at all
WebM is a container built for the web, and the audio inside it is usually Opus or Vorbis, codecs your browser handles fine but that most car stereos, older iPhones, and desktop music players choke on. That's the usual reason someone lands here: a lecture, a downloaded clip, or a music video arrived as .webm and simply won't play where you want it. MP3 is the format almost everything understands. Converting swaps the finicky web container for a file you can drop onto a phone, a USB stick, or an old MP3 player and trust it to work.
Picking a bitrate for the job
Bitrate is the only setting, and it balances size against detail. Music holds up best at 320 kbps, which runs about 2.4 MB a minute and keeps highs and reverb intact. The middle option, 192 kbps, is the safe pick when you're not sure, roughly 1.4 MB a minute and clean for everyday listening. For talk-heavy audio like a lecture or podcast, 128 kbps (around 1 MB a minute) keeps hour-long files small without hurting speech clarity. There's no penalty for choosing higher than you need beyond a bigger file, so lean on 192 when in doubt.
What the MP3 will and won't include
The conversion is deliberately literal: you get the entire audio track, start to finish, at the same volume as the source. Nothing is trimmed, faded, normalized, or merged with another file, so a 40-minute recording comes out as a 40-minute MP3. That predictability is the point, you always know exactly what you're getting back. If you later need to cut a section, boost quiet passages, or stitch clips together, that's a job for a dedicated audio editor. Here, the focus is a faithful, no-surprises extraction that mirrors the original recording.
Tips
- Reach for 128 kbps on lectures and podcasts, speech doesn't benefit from a higher bitrate and you'll save real space.
- Save music at 320 kbps if you plan to listen on good headphones; the extra detail is worth the ~2.4 MB per minute.
- A converted file plays where the .webm wouldn't, on an old phone, a car stereo, or a basic MP3 player.
- Rename the output before saving so a batch of similarly named web clips doesn't get confusing later.

Questions
- Is my file uploaded anywhere?
- No, nothing is uploaded. Your WebM is processed privately on your own device, no account is required, and the MP3 has no watermark.
- Which bitrate should I pick?
- For music, 320 kbps sounds best at about 2.4 MB per minute; 192 kbps (~1.4 MB/min) is a solid all-rounder. For talking, lectures or podcasts, 128 kbps, roughly 1 MB per minute, is more than enough.
- Can I trim the clip or adjust the volume?
- No. The tool extracts the full-length audio at its original volume with no editing. To cut sections or change loudness, open the resulting MP3 in an audio editor.
- Why won't my .webm just play on my phone?
- WebM often stores audio as Opus or Vorbis, which many phones and players don't support. Converting to MP3 gives you a universally compatible file that plays almost everywhere.
