Voice recorder. The audio never leaves your device.

At a glance

Why in-browser recording is different

Every other free online voice recorder works the same way: your microphone audio is streamed to their server, stored there, processed there, and handed back to you as a download. That is a reasonable engineering choice and a terrible privacy one. Whatever you just recorded — an interview, a medical note, a client call, a song idea — now exists on someone else's disk, subject to their retention policy and their breach history.

This recorder uses the browser's own MediaRecorder API. The audio goes from your microphone into memory in this tab, gets encoded to MP3 or WAV by JavaScript running in this tab, and is saved by your browser's normal download mechanism. There is no upload step, because there is no server involved in the recording at all. You can verify this: open your browser's network tab while recording, and you will see nothing being sent.

What to use it for

• Voice memos and quick notes when you are already at a computer and reaching for your phone is slower.
• Interviews and meetings — particularly anything confidential, where uploading the audio to a third party is the thing you are trying to avoid.
• Practice takes and song ideas, then trim them or level them without ever leaving the browser.
• Pronunciation and language practice, where you want to hear yourself back immediately.
• Recording narration for a video, then running it through the podcast prep tool to normalize and encode in one step.

Getting a usable recording

Leave microphone processing on "clean" unless you know you want otherwise. Echo cancellation and noise suppression are implemented in the browser's audio stack and are genuinely good — they remove keyboard clatter, room echo and steady background hum before the audio ever reaches the recorder.

Switch to raw if you are recording music or singing. The processing is tuned for speech and will fight you: noise suppression treats sustained notes as noise, and auto gain pumps the level between phrases.

Watch the level meter while you talk. You want it moving through the middle of its range, occasionally reaching the upper part, and turning red only rarely. Red means clipping, and clipped audio cannot be repaired afterwards — no amount of processing recovers a squared-off waveform. If it is consistently red, move further from the microphone or turn its input level down in your operating system's sound settings.

If the recording came out too quiet, that is fixable: run it through the amplifier or the normalizer afterwards.

Limits worth knowing

The recording lives in memory until you save it. There is no time limit as such, but a very long session on a machine with little free memory can fail, and closing or reloading the tab loses the recording. For anything longer than about an hour, save in sections.

The permission prompt is the browser's, not ours. If you block it by accident, the site cannot re-ask — you need to re-allow it from the icon in your address bar.

Safari records to MP4/AAC rather than WebM/Opus, which the tool handles transparently. Either way the file is decoded and re-encoded to your chosen format before download, so what you get is the same.

Recording quality is bounded by your microphone. A laptop's built-in mic in a hard-surfaced room will sound like a laptop's built-in mic in a hard-surfaced room, and no processing changes that. Getting closer to the microphone is the single biggest improvement available to most people.
