In-browser voice recorder — nothing uploaded
Browser-based voice recorders typically send your audio to a server for storage or processing. This one does not. The recording uses the browser's MediaRecorder API to capture audio directly in memory. The playback preview is a local object URL. The raw download is assembled from the captured chunks without any network request.
MP3 conversion, when requested, uses FFmpeg.wasm — the same engine used by the other audio tools on this site. The ~25 MB WASM binary loads on first use and is cached by your browser. The conversion happens locally and the resulting MP3 is downloaded directly to your device.
Supports pause and resume during recording, a live elapsed timer, and in-browser playback before downloading. Works in Chrome, Edge, Firefox, and Safari.
Frequently asked questions
Is anything uploaded when I record?
No. The recording uses your browser's MediaRecorder API, which captures audio locally. Playback preview and downloads are entirely in-browser. MP3 conversion uses FFmpeg.wasm, also in-browser. Nothing leaves your device at any point.
What format does the recording save as?
The browser chooses the format: Chrome and Edge record as WebM/Opus; Firefox may use OGG/Opus. Both are widely supported. You can download the raw recording in the browser's native format, or use the "Download MP3" button to convert it — MP3 conversion uses FFmpeg.wasm and requires the ~25 MB engine to load.
Can I pause and resume a recording?
Yes. The pause button suspends audio capture without splitting the recording. Resume continues from where you paused. The elapsed timer also pauses and resumes with the recording.
Does the MP3 conversion cost anything or require an account?
No. The MP3 conversion uses the same FFmpeg.wasm engine as the other audio tools on this site. It runs entirely in your browser, is free, and requires no account.
Why does the first MP3 conversion take longer?
FFmpeg.wasm (about 25 MB) downloads on first use and is cached by your browser. After that, subsequent conversions start immediately. The raw download is always instant since it does not require FFmpeg.
