How to convert WMV to MP4
Choose a .wmv file from your device, run the conversion, then download the .mp4 result. This WMV to MP4 converter works in your browser without a signup or a video upload. Keep the tab open while it processes the file.
Turn an old WMV file into a playable MP4
WMV is a Windows Media format that many phones, browsers and non-Windows editing tools don’t open, so converting a WMV recording or download to MP4 makes it playable and shareable again. Like AVI, a WMV is re-encoded at roughly real-time speed, and the first conversion downloads the converter engine, about 31 MB, which later conversions on the page reuse; a DRM-protected WMV file can’t be converted.
Need a transcript from your WMV?
Video transcription is a separate, gated service. Hushscript prepares audio from a local video file in your browser and uploads that prepared audio for speech recognition; the source video stays on your device. Eligible personal accounts can receive 30 free minutes once after successful card verification, or with their first purchase if not already granted. Transcribe a video after signing in.
