Melissa Lee updated on Mar 18, 2022 to Video Converter Tips

If a video is stored in different container formats, its file size varies accordingly. This fact causes a problem that sometimes you may get a video in a huge file size. As a result, you may fail to send the video to your friends because of the file size limitation of some instant communication software. The best solution is to compress the video and make it more convenient to transfer. But it's annoying that some video compressors don't support video formats that are not commonly used, such as WebM. The output videos of some online recording tools are usually contained in this format.
