Today the detailed comparison between desktop and online mkv converter will be given. Just choose the one you like to convert MKV video file.

Part 1: Free Online MKV Converters

Yes! I have introduced 5 best online free video converters recently. Actually you can employ one of them like Zamzar, Convert.Files, Clipconverter, etc. to convert your MKV video files online easily and conveniently. All of these online converters could recognize MKV files. You only need to import your MKV video from local disk or directly drag and drop if the function is allowed. Besides, you can even copy and paste your video URL.

When it comes to the supported output formats, you can choose to convert MKV to MP4, AVI, FLV, WMV, MOV, and many more popular video formats. However, what I should point out is the conversion speed of online free MKV converter heavily depends on your internet connection. Besides, the feature of video settings adjusting is limited. You even get limitation on the file size of conversion files.

Part 2: Desktop MKV Converter Software - Leawo Video Converter

The biggest difference between desktop and online MKV converter is, you have no need to download and install the software if choosing the online MKV converter while you have to do that if choosing the desktop one. However, the desktop video converter will give you total control on your MKV video conversion thanks to its rich features. Besides, the conversion speed will never be affected by the internet connection.
