Lynn Hu Posted by Lynn Hu Aug 11, 2022

WebM VS. MP4 formats: These two video file types are frequently confused because most downloaded videos from website are saved in MP4 or WebM formats. Although MP4 and WebM are video container formats, they use distinct codecs to determine video quality and performance. Don't worry! After reading this post, you should figure out which one to utilize. The sections that follow will explain what MP4 and WebM are and compare WebM VS. MP4. Also, this post will provide you with the steps on how to convert WebM to MP4 for better playback and vice versa.

Part 1: WebM VS. MP4: What Are WebM and MP4 Formats

1. What is WebM?

WebM is a container format created by Google designed specifically for online streaming. This video file type usually comprises VP8, VP9, or AV1 video and Vorbis or Opus audio. The WebM format is now supported by practically all HTML5 web browsers, including Mozilla Firefox, Google Chrome, and Opera. Unfortunately, this video format is not supported by Apple Safari or Internet Explorer without extra plugins, and many video players don't support it.

2. What is MP4?

MPEG-4 Part 14 (MP4) is a popular container format that can hold many videos, audio, subtitles, graphics, and chapters in a single file. Advanced content, such as 3D images, menus, and user interaction, is also possible. Moreover, it can be streamed over the internet in the same way that container formats like WebM or MKV can. Furthermore, MP4 is a universal file format because it can be utilized on a wide range of devices, including platforms, browsers, mobile phones, etc.

Part 2: WebM VS. MP4: What are the Differences? Which is Better?

WebM vs. MP4 File Size

WebM and MP4 are both compressed to minimal file size. Despite this, there is still a file size discrepancy. WebM is substantially smaller than MP4 because it was created specifically for Internet streaming. If you need to quickly download a video from the internet, you can use the WebM format to receive the files rapidly. And so, if you want to save some space on your storage, you must choose WebM file format.

WebM vs. MP4 Quality

The difference in video quality between WebM and MP4 is hard to compare, considering they are both lossy video formats. However, because WebM was explicitly created for the internet, its compression ratio is often larger than MP4, resulting in a higher loss of original quality than MP4. In short, MP4 has a higher quality than WebM.
