Convert WTV to WebM — Free Online Converter

WTV (Windows TV) is the Windows Media Center DVR format, storing broadcast TV recordings with MPEG-2 or H.264 video, AC3 or AAC audio, and EPG metadata (program title, description, channel, ratings) in an NTFS-like container. Windows Media Center served as Microsoft's living room media hub from 2007 until its removal from Windows 10. WebM is Google's open, royalty-free multimedia container based on Matroska, combining VP8/VP9/AV1 video with Vorbis or Opus audio for web-optimized delivery.

WebM is the native video format of the modern web — YouTube uses VP9/AV1, and every major browser (Chrome, Firefox, Edge, Safari 16+) plays WebM natively in the HTML5 video element without plugins.

Converting WTV to WebM transforms TV recordings into web-native video that plays directly in browsers and integrates with modern web platforms. WebM with VP9 video and Opus audio delivers excellent quality at low bitrates, making it ideal for web hosting, self-hosted video platforms, and bandwidth-efficient streaming. This is the modern open-source alternative to MP4 for web delivery.

For users who want to share or host their Windows Media Center TV recordings on the web — personal blogs, educational sites, internal wikis — WebM is the most efficient web-native format. VP9 typically achieves 20-30% better compression than H.264 at equivalent visual quality.
