MP4 (MPEG-4 Part 14)
The most widely supported video format. Plays on virtually every device, browser, and app. Balances quality and file size well thanks to H.264/H.265 compression.
WebM
An open video format developed by Google, optimized for the web. Uses VP8/VP9 codecs for efficient streaming and plays natively in all modern browsers.
WebM is the web's native video format โ it's optimized for streaming and plays directly in every modern browser without plugins. Converting your MP4 to WebM is ideal for embedding videos on websites, uploading to web platforms, or reducing file size for online sharing.
WebM is specifically optimized for web streaming with smaller file sizes. It's open-source and royalty-free, making it the preferred format for HTML5 video on websites.
The quality stays very close to the original. WebM's VP9 codec is highly efficient, so you'll get similar quality at a smaller file size.

Most modern Android phones play WebM natively. On iPhones, some apps support it, but MP4 is still the safer choice for mobile playback.
