Voice Recorder

Record audio with your microphone.

This recorder needs access to your microphone. Your browser will ask for permission when you start — the audio is recorded only in this tab and never uploaded.

Fully private: the recording is captured and held in this browser tab only. Nothing is uploaded or sent to a server, and the microphone is released the moment you press Stop.

Processed on your device. We never see your files.

How to use Voice Recorder

What this tool does

The Voice Recorder captures audio from your microphone and turns it into a downloadable file — without any app, account or upload. You press a button, your browser asks for microphone permission, and the tool records until you stop. While you record you see a live timer and an input-level meter so you know sound is actually reaching the mic. When you stop, you get a player to review the take and a button to save it.

Everything happens inside your browser. The audio is recorded with the built-in MediaRecorder API, assembled into a file on your device, and only written to disk when you click Download. Your voice is never uploaded.

When you’d use it

Recording a quick piece of audio is one of those tasks that shouldn’t need software:

  • Voice notes — capturing a thought, a reminder or a message to send to someone, without opening a phone app.
  • Narration and voiceovers — recording a scratch track for a video, a slide deck or a tutorial before you edit it properly.
  • Practice and feedback — recording yourself rehearsing a speech, a presentation or a language lesson and listening back critically.
  • Interviews and meetings — grabbing a short segment of a conversation (with everyone’s consent) for notes or transcription.
  • Testing a microphone — confirming a new headset or USB mic records cleanly before you rely on it for a call.

Because the recording stays on your device, it is safe to use for material that is personal, sensitive or not ready to share.

How to use it

  1. Press Start recording. Your browser shows a permission prompt the first time — choose Allow so the tool can reach your microphone.
  2. Watch the input-level meter. As you talk, the bar should move. If it stays flat, the browser is not getting sound — check your mic selection and volume before recording anything important.
  3. Pause if you need to. Use Pause to hold the recording and Resume to continue; the paused time is dropped from the final file.
  4. Press Stop recording. The microphone is released immediately — the recording light on your device turns off — and a player appears.
  5. Review and save. Play the take back. If it’s good, press Download to save a recording.webm (or .ogg) file. Press Record again to discard it and start over.

How to read the input-level meter

The meter reflects the loudest sound reaching the microphone right now. A healthy speaking voice should push the bar well across its range without constantly slamming the far end. If the bar barely moves, the mic is too quiet, muted, or the wrong device is selected. If it is pinned at the maximum the whole time, the input is too hot and the recording may distort — move back from the mic or lower the input gain in your system sound settings. Aim for a meter that lives in the middle and peaks near, but not at, the top.

Browser compatibility

In-page audio recording relies on the MediaRecorder API, which is supported in current Chrome, Edge, Firefox and Safari on both desktop and mobile. Chrome, Edge and Firefox record WebM with the Opus codec; Safari records Ogg or MP4. The tool checks for the API when it loads and shows a clear message if your browser does not provide it. Recording also requires a secure context, so the page must be served over HTTPS — which it is.

What the output format means

The file you download is whatever container your browser produced — typically .webm, sometimes .ogg. These are modern, efficient, widely playable formats. The Voice Recorder does not transcode to MP3, because that needs a heavyweight encoder. If a destination requires MP3, convert the downloaded file afterwards. To shorten a recording or cut out a stumble, send it through the Audio Trimmer. To check a microphone before you record, use the Microphone Test.

Your audio is recorded and processed entirely on your device and is never uploaded — recording a private voice note here is completely confidential.

Frequently asked questions

Is my recording uploaded anywhere?
No. When you press Start, the tool asks your browser for microphone access and records the audio with the built-in MediaRecorder API. Every chunk of sound is collected and assembled into a file inside this browser tab — there is no server in the loop. The recording exists only in memory until you press Download, which writes the file to your own device. Nothing is uploaded, logged or stored online. You can confirm this by opening your browser's developer tools, switching to the Network tab, and recording a clip: you will see no upload. That makes the Voice Recorder safe for private voice notes, confidential interviews and draft narration.
Why do I get a WebM or Ogg file instead of an MP3?
Browsers record audio in their own native container — WebM with the Opus codec in Chrome, Edge and Firefox, and usually Ogg or MP4 in Safari. They do not record straight to MP3, and converting to MP3 would need a separate encoding library that adds a lot of weight to the page. WebM and Ogg play in every modern browser and in most media players and editors. If you specifically need an MP3, record here first, then convert the file in a desktop audio editor or a converter you trust.
Will this tool fix a microphone that isn't working?
No — the Voice Recorder records and plays back audio, but it cannot repair hardware or drivers. It is still a useful diagnostic: if the input-level meter stays flat while you talk, the browser is receiving little or no sound. In that case, check that the correct microphone is selected in your operating system's sound settings, that the mic is not muted or its volume turned down, that no other app is holding the device, and that you granted this site microphone permission. For a focused signal check, try the Microphone Test, and to trim the result use the Audio Trimmer.
Can I pause a recording and continue it later?
You can pause and resume within a single session — press Pause to hold the recording and Resume to carry on, and the paused time is left out of the final file. However, the recording lives only in this browser tab. If you close or reload the tab, or navigate away, the in-progress recording is lost. Finish and download a recording before leaving the page.
Is there a time limit on how long I can record?
There is no fixed limit, but the recording is held in your device's memory until you download it, so very long sessions use more RAM. For voice notes, meeting snippets and narration of a few minutes to an hour this is comfortable on any modern phone or computer. For multi-hour recordings, record in shorter segments so a single file never grows large enough to strain the device.
