Why convert AAC to MP4?

Prepare an AAC recording for a destination that expects an MP4 video. The converter adds a static black picture.

  • Why leave AAC. Some older players, car stereos and upload forms skip AAC files.
  • Why use MP4. MP4 suits sharing, uploads, phone recordings, and web playback.
  • What you get. The MP4 output contains H.264 video and AAC audio. Its picture stays black for the whole recording. The video is a black 1280 by 720 frame at 30 frames per second, with the sound from your audio file. It has no artwork, captions or waveform.
  • Kvalitet. Converting AAC to MP4 compresses the sound again to fit the video, which can lower its quality a little. It never improves the sound.
  • Your rights. Convert only files you own or have permission to use.
