4 liveAudio tools that stay on your device
Convert, trim, join, and clean up audio entirely in your browser. Voice memos, interviews, meeting recordings, music — the file is processed on your own device and never uploaded to a server.
Recordings are often the most sensitive files people convert: a client call, a doctor’s appointment note, an interview that was promised confidentiality. A server-side converter requires handing that recording over first. Here the audio never leaves your machine, and you can confirm it in your browser’s Network tab while a tool runs.
Ads and aggregate analytics stay outside the audio-processing path and never receive recordings, file names or output buffers. The tools are also free, with no watermark, signup or daily limit.
Questions
Is my recording uploaded anywhere?
No. The audio is decoded and re-encoded in your browser, so the recording’s contents never reach a server. You can verify it in the Network tab while a tool runs.
Is there a file size or duration limit?
No server quota. The practical limit is your device’s memory — hours-long recordings are typically fine on a normal laptop.
Do I need an account or pay for longer files?
No. There is no signup and no paid tier gating length or quality — the tools are free and ad-supported.
