MP4 to WMV Converter (.mp4 to .wmv)

Convert MPEG-4 Part 14 Video Container (.mp4) files to Windows Media Video (.wmv) directly on your device. MP4 is commonly used for web video streaming, social media uploads, screen recordings, and extracting audio tracks to mp3/wav, while WMV is ideal for converting legacy `.wmv` videos to `.mp4` so they play on macos, ios, android, and modern browsers. Every conversion runs locally in your browser with zero server uploads.
