Online voice recorder - record your microphone in the browser

• Keep the microphone 10-20 cm (4-8 in) from your mouth.
• Record in a quiet room - curtains, carpets and soft furniture cut down echo.
• Watch the meter: the bar should fill most of the way but not hit the end, which means clipping.
• Use headphones when listening back to avoid feedback.

The Noise and echo reduction switch turns on the browser built-in filters: background noise suppression, echo cancellation and automatic gain control. Leave it on for voice notes, interviews and laptop microphones. Turn it off before recording singing or an instrument, because the filters can cut quiet sounds and make the volume pump.

The browser records in its own compressed format, shown under the buttons. Chrome, Edge and Firefox usually produce WebM with the Opus codec, while Safari usually produces M4A (AAC). Recordings are named “Recording 1”, “Recording 2” and so on.

Need MP3? One click on "Convert to MP3" encodes the recording at 192 kb/s on your device and downloads it. MP3 is larger than the native file but plays everywhere, including old players and car stereos. If size matters and the recipient uses a modern phone or browser, the native file is fine.

Estimate the size with bitrate × seconds ÷ 8. Native Opus or AAC speech typically runs at 64-128 kb/s:

The recording is kept in browser memory and is never uploaded. That also means closing or reloading the tab deletes every recording in the list, so download important files right away, especially after a long lecture or interview. You can revoke microphone access at any time in the site settings (the padlock next to the address). The recorder needs an HTTPS connection; on a phone, keep the screen on and the tab in the foreground while recording.

Always tell other people when you record a conversation and get their consent.

• Cut the intro or silences with the audio cutter.
• Join several takes into one file with merge audio, with optional pauses between them.
• Change the format to WAV, FLAC or M4A in the audio converter.
• Record your screen with sound using the screen recorder.
