Free Video Converter
Specifically designed to convert WMV and AVI files, Free WMV AVI Converter can take your Windows video files and convert them into formats more friendly with your devices.
Fully Featured
For a free app, Free WMV AVI Converter has a surprising amount of features on offer. In addition to the core conversion functionality, you can also edit the videos to some degree (cropping the output and trimming the video length). You can add watermarks and effects to the video, alter the output settings (such as resolution and bitrate), and preview the video in-app before converting. Batch conversion is supported, making converting multiple files as painless as possible.
A Great Free App
There are a few limitations that sour this great free offering. Given that the app can convert from WMV to AVI and vice versa, it would be nice to be able to convert from any of the other formats supported. Also the output resolution is limited to 1280×720, which is compounded by a small preview window that doesn’t really let you see any effects added properly. But these are minor concerns for a free application.
