Audio tools that listen to no one else.

Transcribe, extract, convert and trim your audio files for free. Everything happens in your browser: your files are never uploaded to a server.

No uploads. Ever.

Your audio stays on your device

Other sites upload your files to their servers to process them. PizzaVox doesn't: your browser does the work, using technologies like WebAssembly. Recordings, meetings and voice notes stay where they are.

  • Private

    Files never leave your device. No uploads, no copies, nothing to delete.

  • Fast

    No waiting for uploads and downloads: processing starts right away, on your own computer.

  • Free

    No account, no watermark, no subscription. Open the page and use the tool.

— files processed so far, all inside their owners' browsers
0 files stored — 100% privacy, everything happens in your browser

How it works

Three steps, zero servers in between.

  1. Pick the file

    Drop it on the page or select it from your device. It is read locally, not uploaded.

  2. Your browser processes it

    Whisper and FFmpeg, compiled to WebAssembly, run right inside the browser tab.

  3. Download the result

    The finished file is saved to your device. Close the tab and nothing is left behind.

Frequently asked questions

Are my files uploaded anywhere?

No. All processing happens in your browser. From our servers you only download the program (and, for transcription, the Whisper model): your audio is never sent. You can check it yourself in the Network tab of your browser's developer tools.

Is it really free?

Yes, with no account and no watermarks. In the future the site may show a few unobtrusive ads to cover its costs.

Why is the first run slower?

The first time, your browser has to download the processing engine (FFmpeg weighs about 30 MB, the transcription model 31 to 57 MB). After that it stays cached and later runs start immediately.

Are there size limits?

We don't impose any, but your device's memory matters: recent computers handle files of hundreds of MB without trouble, older phones are happier with smaller files.

Does it work on phones?

Yes, on all modern browsers. Transcription is the most demanding tool: on phones the Fast model is recommended.
