Wrap-up

Some of the online video converters, like Convertio, also can convert from WMV to MKV. They do have disadvantages, though. Converting takes longer time as you need to upload, convert, and download the file, especially if your internet connection is not strong. All of the online converters also limit the file size as well as video length. To top it all, the majority of sites are loaded with advertisements, which may be annoying. Of course, if you're only dealing with one or two tiny WMV files to convert, an online converter is still a good option.

That's it for this WMV-to-MKV guide. If you encounter issues or have questions while converting, you can reach out to me on Twitter. I'll be happy to help. Thanks for reading!
