How to Play WebM Files Natively on Windows

WebM is a highly efficient, open-source media file format designed primarily for the web, but playing it natively on a Windows PC can sometimes result in compatibility errors. This guide provides a straightforward overview of how to open and play WebM videos on Windows 10 and Windows 11 without installing heavy third-party software. You will learn how to utilize built-in Microsoft tools, update essential system codecs via the Microsoft Store, and ensure your default browsers handle these files seamlessly.

Understanding Windows Native WebM Support

Historically, Windows Media Player did not support the WebM format out of the box because WebM relies on specific video codecs (VP8 or VP9) and audio codecs (Vorbis or Opus) that were not part of the legacy Windows ecosystem. However, modern versions of Windows have made significant strides toward native integration, meaning you no longer need to download bloated third-party media players just to view a simple video clip.

Method 1: Use Microsoft Edge (The Quickest Native Fix)

Because WebM was built for the internet, web browsers possess the most robust native support for the format. Microsoft Edge, the default browser built directly into Windows 10 and Windows 11, can play WebM files perfectly without any additional configuration.

• Step 1: Locate the WebM file on your computer.
• Step 2: Right-click the file and hover over Open with.
• Step 3: Select Microsoft Edge from the list of applications.

The video will open in a browser tab with fully functional playback controls, offering a crisp, hardware-accelerated viewing experience.

Method 2: Install the Web Media Extensions Package

If you prefer using the native Movies & TV app or the updated Media Player app in Windows, you can enable system-wide native playback by installing an official Microsoft add-on. Microsoft developed a free codec pack specifically to bridge this compatibility gap.

• Step 1: Open the Microsoft Store on your Windows PC.
• Step 2: Search for Web Media Extensions.
• Step 3: Click Get or Install to download the package.

Once installed, this extension integrates directly into Windows. The operating system will instantly recognize the VP8/VP9 and Vorbis/Opus containers, allowing you to double-click any WebM file and play it natively in your preferred Windows media application.

Method 3: Change the Default App Settings

To ensure WebM files always open natively with your chosen player without prompting you every time, you should configure your file associations.

• Step 1: Right-click your WebM file and select Properties.
• Step 2: Next to the “Opens with:” section, click the Change button.
• Step 3: Choose Microsoft Edge (or the newly updated Media Player if you installed the extensions).
• Step 4: Click Set default or OK.

All files ending in the .webm extension will now feature the correct icon and launch natively on your Windows PC with a simple double-click.
