WebM is a video format developed by Google, primarily used on the web. It's the default format for screen recordings in Chrome and many web-based video tools. While it plays well in browsers, many native apps and devices don't support it.

Why convert WebM to MP4?

WebM files don't play on many devices (iPhones, smart TVs, media players) and can't be uploaded to some social media platforms. MP4 is universally supported and plays on essentially all devices and platforms.

Can I convert screen recordings (WebM) to MP4?

Yes! Screen recordings from Chrome, OBS, and other web tools often save as WebM. Upload them here to convert to MP4 for editing in video editors, sharing on social media, or playing on any device.

Does WebM to MP4 conversion affect quality?

With high quality settings, the visual difference is minimal. WebM typically uses VP8/VP9 codecs while MP4 uses H.264. Both provide excellent quality — H.264 in MP4 is simply more universally supported.

How long does WebM to MP4 conversion take?

Conversion speed depends on file size and your device. A typical 10-minute screen recording converts in 1-3 minutes on a modern computer. All processing runs locally in your browser.
