The Free AVI to MKV Converter is a very handy program which allows users to convert their AVI files to MKV. MKV files are uncompressed files and as such take up more space, however, the compatibility is higher than AVI files, and the resolution is also a lot higher than that of AVI files. The Free AVI to MKV Converter is really easy to use. Once the user installs, runs and completes download of the converter, the steps from here on are really easy.. Users need to initiate the program and first identify the AVi files that need to be converted to MKV. Once identified, once can click on the add files button, browse through and select the files that need to be converted and click on confirm, and all the selected files will be uploaded on the Free AVI to MKV Converter. After this, users need to select the order of conversion. If there is a file needed urgently, it can be placed first in queue. The Free AVI to MKV Converter supports batch conversion, which means users can select and upload all files to be converted at one, instead of adding them one at a time. The conversion speed is also very good; the maximum time taken is a few minutes, though it depends on the number of files and the file size. After this, one can also change the resultant quality and resolution. Some items can also be deferred for later. Though the converter remembers the last output folder by default, users can also change the folder destination depending on the need and disk space available. Once all these options have been selected, all the users need to do is click on convert now, and the conversion from AVI to MKV is done immediately.
