Simply drag multiple MKV movie files into the program window with CTRL key, this MKV to QuickTime converter for Mac will automatically convert them all with one click, so you don't have to repeat the process for each.

If you wish, you are free to carry on via "Clip" and "Edit" options at the top menu to edit and add effects to your video. By clicking the "Crop" tab in the editing window, for example, you can remove edge scan lines or black bars of a video to better fit different playback devices' screen.

You can also do others: trim, rotate the video, put watermark, add 3D effects, etc..

Stage 2

In this step, you're required to choose a QuickTime acceptable file as exporting format.

If you convert MKV to QuickTime just in order to play the video on QuickTime player on Mac, you can simply choose a QT friendly format such as HD H.264/MPEG AVC Video (*.mp4) or HD MOV Video (*.mov) from "Profile" drop-down menu at the lower left corner of the interface.

If you've got an Apple device like iPad Air or iPhone 6s plus (2015), a good choice is to go with the device-targeted preset profile under "Apple iPhone" or "Apple iPad" (see our article about how to play MKV on iPad), which has everything (codec, resolution, bitrate, size) optimized to be suitable for device your chosen.

Also, the "Profile" window supports everything from AVI, WMV, MOV, MP3, WMA, M4A, MKA, AAC, AC3 to smartphones, Xbox One and PS4 output, making it dead simple to pick the right file type.

If you do need more fine control to get the best conversion possible, though, the tool provides access to all the video & audio settings by clicking on the "Settings" button next to "Profile".

For example, you could compress your full HD 1080p MKV movies into 720p or 480p videos to cut down the final output size via "Resolution" box (this on the contrary could result in losing the original quality of the movie).

The more you know about the video and audio settings, the more tweaks you can do. This part is pretty open to experimentation, you can leave all of them alone.

Click OK if you have made changes on this screen.

It's worth noting that how big the original MKV files are, your computer hardware, and conversion settings, etc. can greatly influence the time it takes to perform the conversion.

The software shows you a windows with progress bars where you're able to track the converting progress.

You can tell this MKV converter application to open the directory where saves the resulting files after the conversion task finishes by checking "Open out folder" box in the window.
