Voice Recorder
Record your voice in the browser and save MP3 or WAV. Runs in your browser.
About this voice recorder
This online voice recorder records your microphone in the browser and lets you save each take as MP3, WAV or the original WebM, Ogg or M4A file. It is for quick voice notes, podcast drafts, language practice, voiceovers and anyone who needs a clean recording without installing an app.
Nothing is uploaded. Your browser records straight into this tab's memory, and the audio is never sent to a server. That also means takes vanish when you close or reload the tab, so download the ones you want.
You get a real level meter, pause and resume, and as many takes as you like in one list.
Features
Choose your microphone
A device list shows every mic your computer sees, such as a USB mic, a headset or the laptop's built-in one. Names appear once you allow microphone access.
Noise suppression, echo cancellation and auto gain
Three switches control the browser's own clean-up filters. Leave them on for speech in a noisy room. Turn them off for music, where they can make notes wobble or fade.
Level meter and live waveform
A meter shows the peak in decibels and turns red when you clip. A hint tells you when you are too quiet or too loud, and a scrolling waveform shows what was just captured.
Pause, resume and a running timer
Pause mid-sentence and pick up again in the same file. The timer counts only the time you were actually recording.
Several takes, one list
Every recording lands at the top of a list with a player, its length and size. Rename it, play it back, download it or delete it.
MP3 and WAV export
Download the original recording, or convert a take to a 128 kbps MP3 or a 16-bit WAV with one click. The conversion also runs in your browser.
How to use the voice recorder
- 1Pick your microphone and press Test mic to check the level.
- 2Press Record, pause when you need to, then Stop & save.
- 3Play your takes back and download the best one as MP3, WAV or the original file.
When to use it
Voice notes and memos
Record an idea, a reminder or feedback for a colleague and send the MP3. A one-minute note is about 1 MB.
Podcast and video voiceovers
Do several takes of an intro, keep the best one, then trim the silence and breaths at each end before you add it to your edit.
Language and presentation practice
Read a passage, play it back and hear your pace and pronunciation. If you work from a script, check how long your script will take to read first.
Interviews to transcribe
Record a short interview on a laptop, then turn the recording into text without sending it anywhere.
How do I record my voice online?
Pick your microphone, press Test mic and speak at your normal volume. The bar should move into the green and peak somewhere around -12 to -6 dB. If it hits red, move back or lower the input level in your system's sound settings.
Press Record and allow the microphone when the browser asks. Pause whenever you need, then press Stop & save. The take appears in the list, and the mic is released.
What format does the recording use?
Browsers record with their own built-in encoder through the MediaRecorder API, and each browser picks a different file type:
- Chrome and Edge: Opus audio in a WebM file.
- Firefox: Opus audio in WebM or Ogg.
- Safari: AAC audio in an MP4 file, saved as .m4a.
MP3, WAV or the original file?
The original file is the smallest and loses nothing extra. At the 128 kbps this tool asks for, a minute of Opus is close to 1 MB. Some older software and upload forms don't accept WebM, though.
MP3 plays everywhere, from car stereos to old phones. Converting re-encodes the audio once more at 128 kbps, which is plenty for speech. WAV is uncompressed 16-bit PCM, the safest choice for audio editors and transcription services. It is much larger: a minute of mono WAV at 48 kHz is about 5.8 MB.
Need another format or bitrate later? Convert the take to M4A, Opus or another MP3 bitrate in a separate step.
Should I turn noise suppression off?
For talking, usually not. The filters remove fan hum and keyboard clicks, and echo cancellation stops your speakers bleeding into the mic. Auto gain evens out your level if you lean in and out.
For singing or instruments, switch all three off. Noise suppression can chop sustained notes, and auto gain pumps up quiet parts. Wear headphones so the mic doesn't hear your speakers.

Tips
- Record a five-second test take first and play it back with headphones. It catches a wrong mic or a muted input before you record the real thing.
- Keep the mic about a hand's width from your mouth and slightly to the side. That cuts the pops from P and B sounds.
- Download each good take right away. A closed tab, a browser crash or a reload clears the list.
- Want to record your screen and voice together? Use the screen recorder with microphone mixing instead.
Questions
Is my voice recording uploaded anywhere?
No. The recording is made by your browser and kept in this tab's memory, and nothing is sent to a server. That is also why takes disappear when you close or reload the page.
How do I save my recording as MP3?
Press the MP3 button under the take. The tool decodes the recording and encodes it as a 128 kbps MP3 in your browser, then downloads it. It takes a second or two for a few minutes of speech.
Is there a time limit?
No limit is set by the tool. The practical limit is memory: the recording is held in RAM, at roughly 1 MB per minute. An hour-long recording is about 60 MB, which any recent computer handles.
Why can't the page find my microphone?
Usually permission was blocked, or another app holds the mic. Click the icon in the address bar and allow the microphone, close video-call apps, then press Test mic again. The error message names the exact problem.
Why does my recording sound muffled or wobbly?
Noise suppression is usually the cause. It works well for speech but smears music and soft sounds. Turn it off, along with auto gain, and record again. A closer mic position also helps.
Can I record on my phone?
Yes. Recording works in current mobile Chrome and Safari after you allow the microphone. Safari saves AAC in an .m4a file, and Chrome on Android saves WebM. Keep the screen on while recording.
Does the WebM file have a duration?
Yes. Chrome normally writes WebM recordings without a duration, so players can't seek in them. After you stop, this tool rewrites the header with the length and a seek index. The audio itself is not re-encoded.
