How It Works

From permitted download to converted media

  1. Add an MP4 file or a batch
  2. Choose available MP3 output and quality settings
  3. Convert and check audio playback

Select one file or a batch, choose available output settings, then convert and check playback.

Before you process

Available input formats, codecs and export options depend on the installed version. Check the application options for your file; GPU acceleration depends on the codec, device and drivers.

Choose the output for your task

Choose the required audio track and available MP3 quality settings. Check duration, volume and playback in the exported audio.

Questions about this conversion

Does MP4 to MP3 preserve the video?

No. MP3 is an audio output. Keep the MP4 if you also need its video; audio re-encoding may change quality.
