Cum funcționează

Most "convert M4A to MP3" sites upload your audio to a server. This one runs the real FFmpeg encoder inside your browser — your files stay on your device.

  1. 1
    FFmpeg.wasm loads once
    The WebAssembly build of FFmpeg (~30 MB) downloads the first time you use a media tool, then is cached for instant reuse.
  2. 2
    You choose a format and bitrate
    Your audio is loaded into FFmpeg's in-memory filesystem. Nothing is sent anywhere.
  3. 3
    FFmpeg re-encodes the audio
    MP3 (libmp3lame), AAC, Vorbis (OGG), or lossless FLAC/WAV — the same encoders desktop FFmpeg uses, running locally on your CPU.
  4. 4
    The converted file is offered for download
    The result is handed back as a downloadable blob and can be previewed with the built-in player.

No upload, no queue, no file-size cap. Convert voice memos, music, and recordings privately — they never touch a server.
