How to convert AVI to MP4

  1. Upload your AVI file above.
  2. Keep MP4 selected as the output.
  3. Choose Balanced quality unless your workflow needs another setting.
  4. Open Advanced settings only if you need trimming, resolution, bitrate, sample rate or a custom filename.
  5. Start the conversion and download the finished file when it is ready.
Before you convert

AVI is usually less efficient and less web-friendly than modern MP4 or WebM workflows. Re-encoding can change quality and file size even when the extension stays familiar.

Changing a container or codec cannot recreate quality already missing from the source, so keep an important original when possible.
