MP4 to MP3 Converter
File conversion tool. Coming soon.
Local processing⚠️ Browser-based MP3 encoding is not reliably available (no native MP3 encoder, WASM encoders are large and carry patent risk). This tool decodes the audio track and exports WAV (PCM) instead — lossless but larger. For true MP3 output, use a native app like FFmpeg or Audacity.
