Legacy Video Meets Modern Web

You have old MPG video files from DVDs, camcorders, or archived projects, but they won't play properly in web browsers or on modern streaming platforms. MPG (MPEG-1/MPEG-2) was the standard format of the 90s and 2000s, but the web has moved on.

WebM is Google's open, royalty-free format built specifically for the web. Converting your MPG files to WebM makes them playable in Chrome, Firefox, Edge, and Safari without plugins. In our testing, WebM files load faster and stream more smoothly than their MPG counterparts on most websites.

How to Convert MPG to WebM

  1. Upload your MPG file - Drag and drop or click to select your video
  2. Conversion starts automatically - WebM is selected as the output format
  3. Download your WebM - Your web-optimized video is ready

The entire process runs in your browser. No software installation, no account creation, no waiting in queues.

MPG vs WebM: Key Differences

Understanding these formats helps you decide when conversion makes sense:

  • Compression - WebM uses VP8/VP9 codecs with more efficient compression. Files are typically 30-50% smaller than equivalent MPG files while maintaining visual quality.
  • Browser Support - WebM plays natively in all major browsers. MPG requires plugins or external players in most cases.
  • Streaming - WebM was designed for streaming with adaptive bitrate support. MPG was designed for physical media like DVDs.
  • Audio - WebM uses Vorbis or Opus audio codecs, which are more efficient than MPEG audio layers.

For archival purposes, you might keep your original MPG files. For web use, WebM is the clear winner.

When to Convert MPG to WebM

Website Video Embedding

Building a website with video content? WebM is one of the most widely supported formats for HTML5 video. Unlike MPG, it plays without Flash or other deprecated plugins.

YouTube and Social Uploads

While YouTube accepts MPG, WebM uploads process faster and maintain better quality. The platform was built by Google, who created WebM.

Modernizing Archives

Old home videos, corporate archives, or educational content stored as MPG can be converted to WebM for easier sharing and viewing on current devices.

Reducing File Size

Have MPG files eating up storage? WebM compression delivers smaller files without visible quality loss. In our testing, a typical 100MB MPG converted to roughly 50-70MB as WebM.

Quality Considerations

WebM conversion from MPG maintains excellent quality for most use cases. Both formats use lossy compression, so there's minimal degradation during the process. The VP8/VP9 codecs in WebM are particularly good at preserving detail in motion-heavy scenes.

For professional video work where every detail matters, you might consider MPG to MP4 conversion, as MP4 with H.264 offers broader software compatibility for editing. For web playback, WebM is ideal.

Batch Conversion

Have multiple MPG files to convert? Upload them together and convert your entire collection to WebM at once. This is especially useful when migrating old video libraries to a web-friendly format.

Browser-Based Processing

This converter works entirely in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • Works on tablets and capable mobile devices

Your video files are processed locally. They don't upload to external servers, keeping your content private and secure.

Pro Tip

When converting old DVD or camcorder MPG files to WebM, the quality improvement in web playback often outweighs any theoretical conversion loss. WebM's modern compression handles noise and compression artifacts from old footage better than the original format.

Common Mistake

Assuming WebM works everywhere. While browsers support it well, older iOS devices and some media players struggle with WebM. Keep your original MPG files and convert to WebM specifically for web use.

Best For

Embedding video on websites, uploading to platforms that prefer WebM, reducing storage for video archives, and making old MPG recordings playable in web browsers.

Not Recommended

If you need to edit the video in professional software, convert to MP4 instead - it has better editing software support. Also avoid WebM if your audience primarily uses older Apple devices.

Frequently Asked Questions

MPG (also called MPEG) is a video format using MPEG-1 or MPEG-2 compression. It was the dominant video standard from the mid-90s through early 2000s, commonly used for DVDs, VCDs, and early digital video. Many camcorders and TV recorders saved in this format.

WebM is an open, royalty-free video format developed by Google specifically for web use. It uses VP8 or VP9 video codecs with Vorbis or Opus audio. All major browsers support WebM natively without plugins.

Quality loss is minimal and typically not noticeable. Both formats use lossy compression. WebM's modern codecs (VP8/VP9) are efficient at preserving visual quality while reducing file size. For most web and viewing purposes, you won't see a difference.

WebM files are typically 30-50% smaller than equivalent MPG files. A 100MB MPG video often converts to 50-70MB as WebM while maintaining similar visual quality, thanks to more efficient modern compression.

WebM plays in all modern web browsers (Chrome, Firefox, Edge, Safari) without plugins. Most Android devices support WebM natively. iPhones and iPads have limited WebM support, though Safari 14+ handles it. For universal device compatibility, MP4 is better.

Choose WebM for web embedding and browser playback - it's optimized for streaming. Choose MP4 if you need maximum device compatibility or plan to edit the video in software like Premiere or Final Cut. For YouTube uploads, both work well.

Yes, completely free with no hidden costs. There's no account required, no watermarks added, and no limits on the number of conversions.

No. Conversion happens entirely in your browser using local processing. Your video files never leave your device, ensuring privacy and security for sensitive content.

Yes. You can upload multiple MPG files and convert them all to WebM in a single batch. This saves time when converting video archives or collections.

Browsers dropped native MPG/MPEG support because the format requires licensing fees and the codecs are outdated. Converting to WebM solves this - it's specifically designed for browser playback and is royalty-free.
