Hoe het werkt
Most "convert M4A to MP3" sites upload your audio to a server. This one runs the real FFmpeg encoder inside your browser β your files stay on your device.
- 1FFmpeg.wasm loads onceThe WebAssembly build of FFmpeg (~30 MB) downloads the first time you use a media tool, then is cached for instant reuse.
- 2You choose a format and bitrateYour audio is loaded into FFmpeg's in-memory filesystem. Nothing is sent anywhere.
- 3FFmpeg re-encodes the audioMP3 (libmp3lame), AAC, Vorbis (OGG), or lossless FLAC/WAV β the same encoders desktop FFmpeg uses, running locally on your CPU.
- 4The converted file is offered for downloadThe 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 β they never touch a server.
