How it works

How to convert MP4 to WMV

Upload your MP4 file
Drag and drop a MP4 file, or click to browse. Up to 500 MB, and nothing is installed.
Confirm WMV as the output
WMV is already selected, so there is nothing to configure. Switch to another format in the panel if MP4 needs to go somewhere else.
Convert and download
We convert the MP4 on our servers, usually in under a minute. Create a free account to download the WMV, or keep editing it in REQO.

Why convert MP4 to WMV?

MP4 is the closest thing video has to a universal format: an MPEG-4 container that almost always holds H.264 video and AAC audio, which every browser, phone, TV and social platform can play without a plugin.

The practical problem: MP4 is already the safest format, so the usual reason to convert away from it is a specific destination that wants something else.

WMV solves that. Native to older Windows tooling.

FAQ

MP4 to WMV questions

Is the MP4 to WMV converter free?

Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the WMV itself beyond the free-plan badge.

Do I need to install any software?

No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android. Nothing to install at either end. Where MP4 plays: Every phone, browser, TV and editor. Where the WMV you get back plays: Windows; almost nothing else.

Does converting MP4 to WMV reduce the quality?

Converting re-encodes the video, so it is not bit-for-bit identical. We encode at a high quality target, which keeps the result visually indistinguishable from the MP4 on normal viewing. What changes is the container and the codec. WMV holds: Windows Media Video. Converting the same file back and forth repeatedly will eventually show, so keep your original.

How large a file can I convert?

Up to 500 MB per file, which is more footage in some formats than others. MP4: Small for the quality. WMV coming back: Moderate, but dated compression. For anything bigger, trim or compress it first, both are free tools here.

Is my file kept private?

Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
