Convert a WMV File to MP4
WMV to MP4 converter takes a Windows Media video, from an old camera, a screen recording, or an archive, and gives it back as an MP4 that plays on Mac, iPhone, and browsers that do not open WMV. Upload the file and download the converted copy, no software or account setup beyond signing in.
What you get:
- A WMV file converted to MP4, original resolution and framerate kept
- Files up to 2 GB in the free online tool on this page, with no set file size limit in the app
- bulk upload of multiple files, so several WMV files convert in one batch
- A transcript of the audio, with speaker labels, in 100+ languages
- AI chat with any recording, so you can ask the converted video a question instead of watching it back
- Export the transcript as PDF, DOCX, TXT, SRT and VTT
- Free plan: 3 uploads, lifetime, each with the transcript and AI chat included
How to Convert WMV to MP4
- Upload your WMV file: from a computer, phone, or tablet. The free online tool on this page takes files up to 2 GB; the ScreenApp app has no set file size limit.
- Let it process: the file converts to MP4 and the audio transcribes at the same time. Both are ready in your library once processing finishes.
- Download the MP4: open the file and download it. The transcript, speaker labels, and AI chat are attached to the same recording.
The MP4 keeps the source file’s resolution and framerate, so an old low-resolution recording stays low-resolution: converting the container does not add detail that was never recorded. Transcript quality follows the audio: clear narration transcribes cleanly, and an old recording with background noise or a distant microphone will have more gaps. See how we measure accuracy.

Who Converts WMV to MP4
Mac and iOS users convert old Windows Media videos so they play on a Mac, iPhone, or iPad. WMV has limited support on Apple devices, and converting to MP4 removes that problem for good.
Video archivists and collectors work through old WMV archives, screen recordings, and camera footage. Converting a batch of files to MP4 turns an unplayable archive into something a browser or media player opens without a plugin.
Content creators and editors pull WMV footage into a modern editing project. Many editors prefer MP4, so converting first means the clip drops into Premiere Pro, Final Cut Pro, or DaVinci Resolve without a format error.
Business professionals modernize old training videos and presentations recorded in WMV so they play on any employee’s device, regardless of operating system.
Social media content creators convert WMV recordings before uploading to YouTube, Instagram, or TikTok, all of which expect MP4.
