Frequently asked questions

How do I convert WebM to WMV?

Click “Choose Files” and select your WebM file (or drag it onto the page). WMV is already selected as the output, so just click Convert and download your WMV file when it’s ready.

Will I lose quality converting WebM to WMV?

When the video inside your WebM file is compatible with WMV, it is copied without re-encoding, so there is no quality loss at all. Otherwise it is re-encoded at high quality. You can pick the quality yourself in Advanced settings.

Is it safe to convert WebM files here?

Yes. Conversion runs inside your own web browser, so your files are never uploaded to our servers or anyone else’s. Nobody can see them, and nothing is stored after you close the tab.

Is the WebM to WMV converter free?

Yes, it’s completely free. There’s no sign-up, no watermark and no limit on how many files you convert. Each file can be up to 1 GB.

Can I convert several WebM files at once?

Yes. Add as many WebM files as you like and convert them in one go, then download them one by one or together as a ZIP file.
