Make AVI videos from MP4
Get AVI files that open smoothly in older Windows apps, TVs, and engineering tools. For best results, keep the original frame rate and resolution; AVI will often be larger than MP4.
Free to use
Converter App is free. There are no paywalls or locked features, and we do not cap everyday usage. Large files are welcome, and there is no account required. Fair use applies only in extreme cases.
Why choose AVI with Converter App
Converter App produces AVIs aimed at maximum playback compatibility for editors and legacy devices. Files can be bigger than MP4 because we prioritize compatibility over heavy compression.

Privacy protection
We respect your privacy. Your videos are processed securely and are automatically deleted from our servers shortly after the conversion is complete.
