WebM is quickly becoming one of the most popular video formats for web videos. Developed by Google, this video format is preferred for its high quality-to-size ratio. It offers superb compression and is rivalled by few compression codecs. The format is optimized for web streaming, but you often end up downloading WebM videos on your devices. Unfortunately, not many tools support the WebM format. In fact, except for the mainstream browsers, few tools are capable of running WebM videos. So, you'd want to convert them to a mainstream video format like MP4, which is compatible with most devices. And what better way to do it than with VLC! To convert WebM to MP4, VLC Media Player's built-in video conversion tools are a perfect fit. This guide teaches you how to do it with step-by-step instructions.

While there are many video converters out there, VLC Media Player's familiar interface makes it a popular choice for users who already use it as their default media player.

Still, converting videos from WebM to MP4 isn't a straightforward process, so follow this quick tutorial carefully.
- Step 1: Enter Video Conversion Mode
- Step 2: Import WebM Videos

Limitations of Using VLC for WebM to MP4 Conversion
VLC is free, open-source, and easy to use for those who are already familiar with its UI. However, it's not ideal for all users, especially the more serious users who need advanced video conversion features. Here are some areas where VLC is lacking:

- Limited advanced customizations of output for video conversions

FFmpeg is a free and open-source multimedia tool with the most powerful mix of tools under its belt. It can perform virtually anything that has to do with video and audio, including editing, compressing, and converting. FFmpeg natively supports WebM and MP4 video formats and can easily convert videos between the two formats.

Step 1:Install FFmpeg on your Windows desktop> Press 'Windows key + R' > Type 'cmd' in the search box > Hit 'OK'.
Step 2:Copy the path to the folder where your WebM video is located >> Switch to Command Prompt window and type 'cd' followed by 'space' and the file location path you copied earlier >> Press 'Enter'
Step 3:Type 'ffmpeg -i input.webm -c:v libx264 -c:a aac -crf 25 output.mp4', then press 'Enter'.
In the above command, 'input' refers to the input video file name, '-c:v libx264' refers to H.264 video encoding, and '-c:a aac' refers to audio encoding. Also, 'crf 25' refers to quality level, with '0' being lossless and '51' being the highest loss conversion. Lastly, 'output' refers to the output file name after encoder conversion. You can change these options at your convenience.
