Record your voice online

Record your voice with the microphone, watch the level meter, and save as WebM, Ogg or MP3.

Loading tool…

Record a voice memo, a podcast intro, a pronunciation sample or a quick message straight from your browser. The recorder uses your microphone through getUserMedia and the browser's MediaRecorder, with a live level meter so you can see that the sound is coming through and not clipping.

Recordings are saved in the browser's native format: Opus audio in WebM (Chrome, Edge), Ogg (Firefox) or AAC in MP4 (Safari). Opus sounds excellent at small sizes, but if an app, an email recipient or a transcription service wants MP3, convert it with one click; the conversion uses FFmpeg compiled to WebAssembly and runs on your device. Nothing is uploaded, and the recording exists only in this tab until you download it.

How to use it

  1. Click Start recording and allow microphone access when the browser asks.
  2. Speak and watch the level meter: aim for the bar to reach the upper half without hitting the red clip warning.
  3. Use Pause and Resume to skip breaks, then click Stop.
  4. Play the recording back, then download it as is or convert it to MP3 and download that.

Frequently asked questions

Is my recording sent anywhere?

No. Audio goes from your microphone to the browser's recorder and stays in this tab. MP3 conversion also happens locally with FFmpeg.

The browser did not ask for the microphone, or the meter stays flat. What now?

Check the microphone icon in the address bar and allow access for this site, make sure the right input is selected in your system sound settings, and close other apps (video calls) that may hold the microphone.

Should I turn off echo cancellation and noise suppression?

Keep them on for speech in a normal room. Turn them off to record music or an instrument, because those filters treat sustained tones as noise and can make music sound thin or pumping.

How long can I record?

There is no fixed limit; Opus uses about 1 MB per minute at the browser's default quality. Very long recordings are held in memory, so download them when you are done.

Does it work on iPhone and Android?

Yes, in current Safari and Chrome. On iPhone the recording is AAC in an MP4 (.m4a) file; converting to MP3 works the same way.
