WMV to WEBM Converter (.wmv to .webm)

Convert Windows Media Video (.wmv) files to WebM Open Media Container (VP9 / Opus) (.webm) 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 WEBM is ideal for html5 background videos, browser screen recordings, discord clips, and lightweight web embeds. Every conversion runs locally in your browser with zero server uploads.
