About AVI to MP4 conversion

Each AVI is re-encoded to H.264 MP4, bringing decades-old footage onto phones, TVs and editing timelines. Local processing means your family videos stay yours.

Good to know: Browser-based re-encoding takes a few minutes per video minute. Leave the tab open until the download appears.

  1. Drop your AVI file onto the box above, or click Choose files.
  2. The output format is already set to MP4 — adjust it per file if you need something else.

Free, no account, no watermarks — and because the conversion runs in your browser, your files are never uploaded to a server.
