Convert WTV to MP4 — Free Online Converter

WTV (Windows TV) is the DVR recording format created by Windows Media Center, Microsoft's living room media platform that shipped with Windows Vista through Windows 8.1. WTV files store broadcast television recordings — MPEG-2 or H.264 video with AC3 or AAC audio — plus rich EPG metadata including program title, episode description, channel name, recording time, and parental ratings. The container uses an NTFS-like internal structure supporting multiple multiplexed streams. MP4 (MPEG-4 Part 14) is the universal multimedia container, playing on every smartphone, computer, smart TV, and web browser worldwide.

Microsoft discontinued Windows Media Center in Windows 10, permanently ending the platform that created WTV files. No active software produces WTV recordings today, but millions of personal TV recordings still exist in home archives — entire seasons of favorite shows, sporting events, holiday specials, and family recordings that span the 2007-2015 Windows Media Center era.

WTV is the definition of a stranded format. Modern Windows 10 and 11 cannot play WTV files without third-party software, and macOS, Linux, iOS, and Android have never supported the format at all. MP4 is the universal solution — it plays everywhere, streams everywhere, and uploads everywhere. Converting WTV to MP4 is the single most important step in rescuing a Windows Media Center recording library.

MP4 with H.264/AAC is accepted by every platform: YouTube, Vimeo, social media, messaging apps, Plex, Jellyfin, Kodi, web browsers, and all mobile devices. This makes WTV-to-MP4 the standard conversion for making TV recordings permanently accessible.
