Free MKV To AVI Converter

Free MKV To AVI Converter 2.1

It allows users to quickly convert MKV to AVI and AVI to MKV

Free MKV to AVI Converter is intended to transcode between video formats. It is specifically intended to make the contents of MKV files playable on various devices by converting them to more readily supported formats, such as AVI or MPG. However, it actually supports a very long list of source formats, like WebM, DIVX, WMV, ASF, QT, FLV, SWF and many others.

The program has a nice interface; yet, it seems to me unnecessarily overcomplicated compared with other similar tools. Since it supports batch conversion, you can start by creating a list of files to convert, which you can do by browsing or dragging the desired files or folders. If you do not have much experience, there is nothing to worry about for the tool automatically uses appropriate conversion settings that do not affect the original quality.

Should you want to use a customized output profile, it is possible to configure such parameters as target format, codecs, bitrate, number of frames per second, resolution and aspect. Luckily, you can save your personalization in case you need it in the future. Moreover, if the original MKV comes with multiple audio tracks, it would necessary to pick the one you want to keep. In addition, some very simple editing operations, like flipping, cropping and rotating. Unfortunately, other editing operations (cutting, splitting and merging) that are possible with other converters are not allowed.

All in all, Free MKV to AVI Converter can solve the problem of your MKV files being incompatible with the intended device. The good news is that the product is absolutely free to use. Finally, you should know that it is available in both 32- and 64-bit versions. Of these, the 64-bit version is preferable as it converts up to 25% faster. It is also an advantage that there is a portable version as well.
