When you download a video, you're often given a choice of formats. Understanding the difference between MP4, WebM, and others can help you save space and ensure compatibility.
The Versatility of MP4
MP4 (MPEG-4 Part 14) remains the most widely compatible format. Whether you're playing a video on an old smart TV or a brand-new VR headset, MP4 just works.
The Efficiency of WebM
Developed by Google, WebM is designed specifically for the web. It often offers smaller file sizes than MP4 at similar quality levels, making it great for web developers, but slightly less compatible with legacy hardware.
Which Should You Choose?
If you're unsure, always go with MP4. It offers the best balance of quality, file size, and "play-anywhere" reliability.
