A MP4 converter is primarily used to change video format from MP4 to others or others to MP4. MP4 converter is in need for multiple reasons. Sometimes, incompatible videos (M2TS, MKV, AVI etc.) should be converted as MP4 for flawlessly playing on devices or sharing online. In turn, special requirements lead us to convert MP4 to other formats (for example FLV, 3GP) for size reducing. Here, I list top 3 ranked free MP4 converters of 2017 with free download links and detailed reviews.

Speed Comparison of Top 3 Free MP4 Converters
Conversion speed of a MP4 converter is the most concerned and output quality is another thing to consider. So, I do a speed comparison test of the top 3 free MP4 converters.
• What to do: Convert a MKV file to MP4 (H.264) with original resolution.
