Why convert WEBM to MP3?

WEBM carries Opus or Vorbis audio, which many editing tools and clients refuse. MP3 plays everywhere and is small enough to email a review copy.

Should I use MP3 or WAV?

MP3 for review, notes and transcription. WAV when the audio goes back into an edit or a mix.

What sample rate and bitrate come out?

The MP3 is encoded at 320 kbps. WEBM is decoded by the browser, which normally hands back 48 kHz; the rate is shown before export and you can pick another one.

No. Screen recordings and internal reviews stay on your machine; the decode and the MP3 encode both run in the browser tab.

WEBM audio in practice

Opus and Vorbis

WEBM carries Opus or Vorbis audio. Both are efficient modern codecs, and both are poorly supported by editing software, which is why converting is usually the first thing you do with a WEBM recording.

Choose MP3 only for listening

If the recording will be edited, export WAV instead and keep MP3 for the version you send round.

Professional use cases

Podcasting

Turn a browser-recorded remote interview into a file your editor accepts.

Video editing

Your audio stays on your device

Decoding, processing and export all run in your browser: compressed formats are decoded with the Web Audio API, and WAV, AIFF and MP3 files are written by JavaScript in the page. Your audio is never uploaded to our servers. Only anonymous page analytics and, if you sign in, your account and payment details go online.
