Want to learn how to convert WebM to MP4 in VLC? Whether you’re on the hunt for the best way to play WebMs on an iPad or iPhone; you need to save space on your computer by compressing your WebM files to smaller MP4s; or you’re looking for how to share WebM files, learning to convert file formats is a lot easier than finding a WebM player for every device you own. So, in this article, we’ll walk you through the step-by-step process to use VLC for WebM conversions. We’ll also explore an alternative if VLC fails to convert for you, and we’ll dive into the pros and cons of each program.

How to Use VLC to Convert WebM to MP4

To get started, let’s discuss how to use VLC to convert WebM to MP4. VLC is a free media player that you can download and use on your computer. You can also use it as a WebM player, and VLC can convert to other file formats as well. You can also convert back and forth, changing MP4 in VLC to WebM, if you need to. Because VLC runs on open-source software, it can be a little tricky to start using as you learn how to convert WebM to MP4. VLC can, however, work well for this purpose in most cases. That’s why we’ve taken the time to provide detailed instructions on how to convert files. Follow these six steps to complete the VLC WebM converting process.

Tap the down arrow next to the orange Download VLC button to choose the appropriate version for your operating system (e.g., Windows, macOS, Linux, etc.). Follow the download and installation instructions, and you’ll be all set. Open VLC Media Player and proceed to step 2.
