When to use MP4 to AVI Converter

Use this tool when the output format is required by another app, website, device, client, or upload portal. Convert a small test file first if the source file has complex formatting or sensitive content.

Make video files easier to share and play

Video conversion is helpful when a device, browser, editor, or upload portal does not accept the original format. Larger videos can take longer, so start with the shortest useful clip when possible.

Use MP4 for broad compatibility.
Compress videos before uploading to strict file-size portals.
Watch the first and last few seconds after conversion.

Before you upload

Confirm the source file is one of these formats: MP4.

Keep the file under 25 MB for this plan.

Open the downloaded AVI result and check the important pages, text, images, or audio before sharing.

Avoid uploading confidential files unless you are comfortable using an online converter for that document.
