WebM is one of the many formats that YouTube supports for upload. Although many users prefer to convert YouTube to MP4, the video format used most frequently, some of you may be willing to convert YouTube to WebM given its smaller size (compared with MP4).

Since WebM is a newer video format and is less compatible compared with MP4, you may think it is difficult to convert YouTube videos to WebM. Actually, WebM is a popular format that YouTube will recommend when the publisher wants to convert their source videos. Thus, many of the videos on YouTube are actually saved as WebM for you to watch online.

To satisfy your needs to convert YouTube to WebM, there are three tried and worked tools introduced for you.

Part 1. How to Convert YouTube to WebM with EaseUS Video Downloader

Both MP4 and WebM are two formats that are supported by EaseUS Video Downloader, a reliable video downloader for PC. With this powerful tool, you will be able to convert YouTube videos to WebM or MP4 in 8K/4K/HD and more. The highest quality you can download depends on the quality of the video source from YouTube. For example, if the publisher uploads a video in 8K to YouTube, you can download the YouTube to WebM in 8K or any quality below.

What's more, EaseUS Video Downloader allows you to convert YouTube to MP3 in high quality. Without downloading the video file, you can rip audio from an online video easily. Apart from YouTube, this tool supports other 1000+ sites from which you can download online videos and audio files freely.

To convert YouTube to WebM:

Step 1. Copy the URL of the YouTube in the address box and click "Search."

Download YouTube video - 1

Step 2. Check the video and click "Download."

Download YouTube video - 2

Step 3. Choose WebM as the target format, select a quality you prefer to download, and then click "Download."

Download YouTube video - 3

Step 4. When the downloading process has done, click "Open" to check the YouTube video.

Download YouTube video - 4

Note: The latest version does not support this function.

As you can see from the images above, there is a "Video to MP3" feature in EaseUS Video Downloader. It is quite helpful if you want to extract audio from a local video saved on your computer.

Part 2. How to Convert YouTube to WebM Online

Whether you want to convert a YouTube video to MP3 or convert YouTube to WebM, there are always online converters for you to choose from. It's really easy to download online videos or audio files using an online service. But it's also really hard to find a workable YouTube to WebM converter that is trustworthy. There are the issues you may encounter when you try to use an online tool:

  • It doesn't support WebM at all.
  • It doesn't work after you click the "Download" button.
  • It will redirect you to other unrelated pages and make the video downloading complex.

Given these reasons, it's advisable to use a clean and safe YouTube to WebM converter like EaseUS Video Downloader.

If you still want to use an online equivalent, here is an example:

Step 1. Copy the URL of the YouTube video you want to convert.

Step 2. Go to the online YouTube to WebM converter and put the URL into the address box.

Step 3. Select WebM as the target format and click "Download."

Step 4. Wait for the file conversion to complete.

Step 5. Click "Download" again to save the WebM file to your computer. (Attention: You will be redirected after you click the button.)

Part 3. How to Download YouTube to WebM via an Extension

Being equally popular as the two solutions above, using a YouTube video downloader extension is also one of the workable ways to convert YouTube videos to WebM. Since most browser extensions work similarly, I'd like to show you how to use the one called YouTube Video Downloader.

Step 1. Add the YouTube Video Downloader extension to your browser and restart it.

Step 2. On YouTube, play the video you'd like to convert.

Step 3. Click the icon of the extension from the toolbox bar.

Step 4. Click "Start Processing" next to the WebM video you want to download.

Step 5. After the conversion, follow the onscreen instructions to save the YouTube video to your computer.

The Bottom Line

Since WebM is generally used to save videos in high quality, the video size you will download is 2K/4K/8K in most cases. Thus, it may take a long time to convert and download the WebM video when you use one of the tools. Just be patient and wait for the downloading process to finish without interruptions.
