Why convert AVI to MP4?

Make AVI video play in more apps, phones and upload forms.

  • Why leave AVI. Phones, browsers and social uploads often reject AVI, and the files can be large.
  • Why use MP4. MP4 suits sharing, uploads, phone recordings, and web playback.
  • What you get. The converter first tries to copy the video and audio without compressing them again. If that fails, it encodes H.264 video and AAC audio. Keep the original. The converted file can differ in size and metadata, and some apps may still not play it.
  • Kvalitet. Converting AVI to MP4 often keeps the quality. The converter first tries to copy the video and audio without compressing them again. If it has to compress them, it uses H.264 and AAC, which can lower the quality a little. It never adds resolution or detail.
  • Your rights. Convert only files you own or have permission to use.
