Questions
How do I convert WebM to MP3?
Open the converter, pick the WebM, trim it if you like, then tap Extract audio. MP3 is already chosen on the download button, so the next tap saves it.
Does my WebM get uploaded?
No. The conversion runs in your browser, so the video never leaves your device, and a big file doesn't wait on an upload.
Is there a size limit?
Videos can be up to 500MB and 20 minutes long. Trim first if you only need part of it.
What quality is the MP3?
Good for listening on any phone, car or speaker. If you're going to edit the audio in a music or video app, download it as WAV instead: it's larger, but nothing more is lost when you edit it.
Does it work on iPhone and Android?
Yes, in a recent version of Safari or Chrome, with nothing to install. Pick the video from your Photos or Files.
Is it free?
Yes. No sign-up, no watermark, and no limit on how many videos you convert to MP3.
