Convert WebM to MP3 Using Command Line by FFmpeg

Another free and easy solution to convert WebM format to MP3 is FFmpeg. This one is a free, open-source command-line tool used to encode, decode, transcode, and play almost any audio or video format, which, of course, includes the ability to convert files. Now, compared to the first solution, this one is for tech-savvy users. Why? Since it is a command-line-based tool, it is extremely difficult to use if you are not familiar with command lines. Here's how to use it:

Step 1.Visit the FFmpeg download site on your browser, select the "Windows" option, and click "gyan.dev" or "BtbN". After that, head to a new tab and select the target "FFmpeg build" to start the installation process.

Step 2.Next, use the "7-Zip compressor" to decompress the FFmpeg downloaded file. After that, go to your "OS/C:" folder and create a new folder with the name FFmpeg.

Step 3.Then, copy the decompressed files and paste them into the FFmpeg folder that you created earlier. Next, go to "My computer", access "Properties", and head to "Advanced system settings".

Prepare FFmpeg

Step 4.After that, choose "Environment Variables", select "New", and replace the variable name with "Path". Next, enter the "C:\FFmpeg\bin" for the "Variable" value and click the "OK" button to apply the alterations.

Step 5.Next, press "Windows and R", input "CMD", and click "OK" to access the Command Prompt panel. After that, press the "Space enter", "enter cd", hit the "space bar", and then enter the file location of the WebM file you wish to convert.

Step 6.Lastly, enter this command "ffmpeg -i source_movie.webm -vn output_movie.mp3" and press "Enter" to enable FFmpeg to start the conversion process. And that's how you use FFmpeg to convert from WebM to MP3.

How to Convert WebM to MP3 with VLC

If you find FFmpeg to be quite complicated and overwhelming WebM to MP3 converter, you can try VLC instead. Similar to FFmpeg, VLC is also a free, open-source solution. The difference is that, unlike FFmpeg, VLC is a powerful media player that can play nearly any video and audio file, and it also has the ability to do file conversion, like WebM format to MP3. However, this is not for beginners as well, and conversion is not a straightforward process, but it is easy to follow. Here's how:

Step 1.Download and install VLC, and launch it afterward. Next, click the "Media" tab, select "Convert / Save", click the "+Add" button, import the WebM file, and click "Convert / Save".

VLC Import WebM

Step 2.Next, click the "Profile" dropdown button, scroll down, and select the "Audio - MP3 (.mp3)" option to convert your WebM file to MP3.

Step 3.Once done, click the "Browse" button and choose your preferred output file location. After that, click "Start" to initiate the conversion process.

Use Audacity to Convert WebM to MP3

The last desktop-based WebM to MP3 audio converter that you can try is Audacity. It is also a free and open-source program that provides a timeline-based audio editing to edit WebM files, including recording tools. Now, the thing with using this one is that it doesn't natively support video imports. Therefore, to make it possible to use as a solution, you need to download and install the FFmpeg library, which makes everything a bit hassle. But it is still worth it. Here's how to use it:

Step 1.First, visit the Audacity Support page and look for a process to install the FFmpeg library in Audacity. Make sure to navigate to the section that is suitable for the operating system that you are running.

Audacity Install FFmpeg

Step 2.Next, launch Audacity on your desktop, click the "Edit" tab, and select "Edit". Then, head to "Preference", then on the pop-up panel, select "Libraries", and choose "FFmpeg Library Locate". After that, select the downloaded "FFmpeg library" and click the "OK" button.

Step 3.After that, click the "File" tab, choose the "Open" option, and select the "WebM" file you wish to convert. Then, click the "File" tab again, click the "Export" button, and select "Export as MP3". Finally, give the output a name and click "Save" to start the WebM to MP3 free conversion process.
