WMV to MKV Converter (.wmv to .mkv)

Convert Windows Media Video (.wmv) files to Matroska Multimedia Container (.mkv) directly on your device. WMV is commonly used for converting legacy `.wmv` videos to `.mp4` so they play on macos, ios, android, and modern browsers, while MKV is ideal for remuxing obs studio recordings to mp4 for premiere/davinci resolve or extracting audio tracks. Every conversion runs locally in your browser with zero server uploads.
