Convert MP4 to AVI when you need compatibility with older tools, legacy editors, or systems that still expect AVI.
AVI is an older container that many enterprise and legacy environments still recognize. If you want a modern, smaller web format, use MP4 to WebM. If you already have AVI and want universal playback, use AVI to MP4.
Best for
- Legacy apps and older video workflows
- Enterprise systems with AVI-only acceptance
- Quick conversions without installing desktop software
Conversion is fully local in your browser using FFmpeg WebAssembly.
Why use Client Tools?

How it works
Unlike other converters that require you to upload your files to a cloud server (which creates a privacy risk), Client Tools uses advanced WebAssembly technology to run professional image processing software directly inside your web browser.
