A video converter is a specialized file converter that allows you to convert one kind of video format (like an AVI, MPG, MOV, etc.) into another. If you've found yourself unable to use a certain video in the way you wanted because the format wasn't supported, a free video converter can help.
Important: Every video converter program listed below is freeware - no shareware or trialware here. I also haven't listed any video converters that trim or watermark videos.
Here's a list of the best free video converter software and free online video converters available today:

The only thing I didn't like about Any Video Converter was the window that appeared after each video conversion suggesting that you upgrade to the "ultimate" version to enable more output formats.

Important: Be careful on TFC's website. There are often a number of advertisements that appear to be the download link for their free video converter software, but of course they are not. The real download button is orange and is next to the license, version, and compatibility information.

One thing I dislike about iWisoft Free Video Converter is that it opens their website every time the program opens so it can check for an update, and there doesn’t seem to be an option to disable it.

MPEG2 formats such as MPG, SVCD, TS, and VOB will also work with DivX Converter, but only for the first 15 days of the install.
To use DivX Converter to create videos up to 4K, you must select the option called Enable DivX HEVC Plug-in during setup, which isn't chosen by default.
Before the installer is finished, DivX Converter tries to install a toolbar. To avoid this, you must deselect the toolbar option and then choose Skip.
