There are many good, free video converters so you do not have to rely on commercial tools. The first step in choosing a free video conversion tool for you is to start by looking at the most popular products in the niche. They may not be perfect, but their popularity shows they are a solid application that benefits from constant development.
Also, a popular online video conversion tool is likely to contain many features and is quite easy to use, which is very important if you want to convert videos between different formats quickly.
No matter if you are a power user or a beginner, the user-friendly UI will make the conversion process quicker. A well-organized layout will not only let you navigate quickly to the functions and settings that you need, but it will also require very few clicks to convert video.
Supported video formats
This is not a problem if you need to convert between popular video formats such as AVI or DivX, but if you need a conversion to/from a less common video format you must choose a video converter accordingly. Before anything else, check to see if the video format you are interested in is supporting.
A good video converter will have no or very little quality loss when converting between different video formats. Although it's nice to benefit from the conversion speed that is very fast, quality is more important in the end.
