How to Convert MP4 to FLV with Best 5 Ways

Vanessa Chiang updated on Nov 22, 2021 to Video Converter Tips

MP4 (MPEG-4) is a standardized video container for both audio and video. There is no doubt that you can play videos in this format on all devices and players, but it's not the best choice for web streaming. On the contrary, the FLV (Flash Video File) container is suitable for video streaming on the internet for many reasons.

For example, the file size of an FLV video is smaller than that of the same video in MP4 format, and this is the main reason people need to convert MP4 to Flash file format (FLV). Indeed, a great MP4 to FLV Converter is indispensable for the conversion. This post will give you a list of the available converters on different platforms. Keep reading and select the best one for you.
