How about WebM to MKV Converter Online?

When you search how to convert WebM videos to MKV on Google, the first few rows of results are often ads of online video converters. These services seem to be a shortcut to your desired conversions. But what might disappoint you is that many of these converters hold various types of restrictions. One of the most obvious limits is the size restriction. Even their paid plans won’t let you go over a 4GB size, meaning that you are out of luck to use the service if you have a big video file. What’s more, online conversions can get easily influenced by your network conditions. If you don’t have a strong and stable internet, you could waste your time waiting for the online conversion to complete. There is also concern over the security of online converters as many of these converters have suspicious ads and pop-ups on their sites.

In a word, we would suggest that you find a reliable online converter before you do any online conversions. But we would most recommend you use the desktop converter for a more stable and safe conversion experience.
