Voice Recorder & Microphone Test
Record your voice in the browser, watch a live level meter that doubles as a mic test, then play it back and download the audio. No upload, no install — your recording stays on your device.
Runs entirely in your browser — your recording is never uploaded.
- No upload Your video never leaves your device — it is processed locally.
- Works offline After the first load it runs with no internet connection.
- No size or daily limits No file caps, no paywalls — only your device memory.
- Private & safe Skip sketchy upload sites; nothing is sent to a server.
How it works
When you start a test or a recording, the browser's getUserMedia hands the page a
live stream from your microphone. The level meter is driven by the Web Audio API: an
AnalyserNode reads the raw waveform many times a second and the tool computes its
loudness (RMS) to size the bar, which is why it reacts instantly to your voice. Recording is
handled by MediaRecorder, which encodes the same stream into an audio file on your
device. Both run locally — no audio is uploaded — and the finished file lives in memory until
you download it.
How to record your voice
- Press Test microphone and speak — the meter should move with your voice.
- Press Start recording and allow microphone access if the browser asks.
- Press Stop & save when you are done; a player appears for playback.
- Listen back, then click Download to save the audio file.
The page must be served over HTTPS and you must grant permission — both are browser privacy safeguards. The recorder does not echo your voice to the speakers while recording, to avoid feedback.
Why record in the browser instead of installing an app
A voice memo is often personal — a reminder, a song idea, an interview, a pronunciation check — and uploading it to an online recorder hands that audio to a third-party server. Recording in your browser keeps it on your own device with nothing to install and no account to create. It also avoids the safety concerns around free file-handling sites: in March 2025 the FBI warned that some free online tools were being used to spread malware, so keeping your audio local is simply the safer choice.

| Files stay private | Yes — never sent | Sent to a server |
Common uses
Testing a headset or built-in mic before a meeting or interview, capturing a quick voice memo or to-do, recording a song idea or vocal take, practising a speech or language pronunciation, saving an interview, or narrating notes. The level meter on its own is a handy standalone microphone test even if you never press record.

Frequently asked questions
How does the microphone test work?
The live level meter is the mic test. When you press "Test microphone" (or start recording), the tool reads your mic through the Web Audio API and shows the input level as a moving bar in real time. If the bar moves when you speak, your microphone is working and the browser has permission; if it stays flat, the mic is muted, the wrong input is selected, or permission was denied. Use it to check a headset or built-in mic before an important call or recording.
Is my voice recording uploaded anywhere?
No. Audio is captured by your browser directly into memory on your device using MediaRecorder, played back from there, and saved as a local file when you download it. Nothing is sent to a server, there is no account, and closing the tab clears the recording from memory. A voice note can be personal, so keeping it entirely on your own machine is the safest default.
What audio format do I get — can I get MP3?
The tool records in the best format your browser supports and labels the download accordingly. Chrome, Edge and Firefox record WebM with the Opus codec, which is small and high quality; Safari records MP4/AAC (an .m4a file). A few browsers expose MP3 directly, and when yours does the tool will use it. If you specifically need an MP3, record here and then convert the file with the Audio Converter on this site, which also runs fully in your browser.
Why can I not hear my own voice while recording?
The recorder intentionally does not play your microphone back through your speakers while you record, because that would cause an echo or a feedback howl, especially without headphones. The level meter gives you visual confirmation that your voice is being picked up. Once you stop, an audio player appears so you can listen to the full recording before downloading it.
Does it work on a phone?
Yes. Voice recording works in mobile Chrome, Safari and other modern browsers, since microphone access and MediaRecorder are widely supported on phones. You will be asked for microphone permission the first time. On all devices the page must be served over HTTPS and you must grant permission, both of which are privacy safeguards built into the browser.
Does it work offline?
Yes. The site is a Progressive Web App, so after your first visit it loads and records with no internet connection. Recording uses only your browser's built-in features, so nothing needs to download for it to work.
All recording happens on Video Tools entirely within your browser. Your audio is never uploaded to a server.
