Speaking of WEBM, it is a free and open format for audio-visual media files on the internet. Converting videos from their native MP4 format to WEBM is popular because it offers superior compression and the highest quality real-time video delivery.

In order for you to know what settings to make while converting MP4 to WEBM, we will now quickly introduce the WEBM format. Then, using a video converter, we will show you step-by-step how to convert MP4 to WEBM.

Part 1: Why Do You Need to Convert MP4 to WEBM?

Frequently used to store both video and audio, MP4 is a highly adaptable and compressed video and digital multimedia container format. It was developed using the ISO / IEC 14496-12: 2001 standard by the ISO / IEC and the Moving Picture Experts Group (MPEG). One of the major video file formats used for downloading and streaming videos from the internet is MP4, which is an international standard for audio-visual coding.

WEBM is a media file format that is open and free of royalties. The file container structure, video, and audio formats are all defined by WEBM. The major objective of WEBM is to provide a royalty-free substitute for use in HTML audio and HTML video 5.

Here is a summary of some justifications for converting MP4 to WEBM:

  • The primary distinction between MP4 and WEBM is the type of video codes that are employed. While MP4 utilizes H.264, WEBM uses VP8 or VP9. VP8 would provide higher quality than H.264.
  • Additionally, they are also compressed file formats. But WEBM files typically have a smaller file size than MP4 files. WEBM files hence require less storage space.
  • WEBM files can be played back on portable devices like power tablets since they have a smaller computing footprint.
