Oncea file clinic

MP3

Same tool as Convert audio. A voice note or other audio file, in this tab. No account. The download is just a file.

Before you start. About 80 MB is the ceiling. Desktop Chrome or Firefox is the setup that works. iPhone and large files may fail — the work stays in this tab, and the browser can run out of memory.

Drop a voice note, wav, m4a, ogg, or opus. Default out is MP3. Nothing is uploaded.

How to make an MP3 here

  1. Read the 80 MB / desktop note above the zone. iPhone and large files may fail.
  2. Drop one audio file or a WhatsApp voice note.
  3. MP3 is the default. 192 kbps is the default bitrate. WAV, AAC, and OGG are on the same control if you need them.
  4. Click Convert audio. First run in a session loads ffmpeg.wasm (~25 MB) from this origin.
  5. The result plays in the tab. Download it. No watermark, no signup.

Longer how-to, limits, and FAQ live on /convert-audio. Have a video instead of audio? That is Extract audio.

FAQ

Is the file uploaded?

No. Local verb. Close the tab and the bytes are gone.

Do you watermark it?

No copy, no watermark, no paywall on the result.
