The best avi to mp4 converter that works well in Windows 11?

Clipchamp is a video editor pre-installed on Windows 11. You can use it as a free avi to mp4 converter, but it re-encodes all imported footage, so the quality of the output video will be slightly reduced.

It allows you to convert AVI files to the standard MP4 format without downloading any additional software, but this free avi to mp4 converter cannot perform a lossless stream copy to preserve all the details of the original video quality.

Instructions: Search for the app in the Windows Start menu and open it. Click Create a new video, then click “Import” and select your AVI file. Drag and drop the video clip onto the timeline, click the Export button in the upper-right corner, select 1080p or your preferred resolution, and then click Export again to start the conversion.

Its advantages include: being built directly into Windows 11; simple drag-and-drop operation suitable for beginners; and the integration of basic video editing tools in addition to format conversion.

Its disadvantages include: inevitable re-encoding that results in slight loss of video quality; slow export speeds for long AVI videos; and the lack of a lossless conversion mode.

This allows you to quickly convert local AVI videos into MP4 files that can be played on Windows 11 devices. The tool is suitable for everyday, general-purpose format conversion tasks and is not intended for situations requiring ultra-high-definition reproduction of the original video.
