How to Convert ISO to MKV: 3 Ways Introduced Here

"I've ripped my DVD collection to ISO files at 1:1 ratio. But now I want to convert ISO to MKV, for the sake of playing on Plex, and also to release space for my computer. The file size of an ISO image is as big as the source disc. An ISO file will eat up a few gigabytes. So, my question is how I can convert ISO files to MKV format. Which software should I use?"

Ripping disc to ISO image can maintain full content and original quality, but we might need to do conversion because of compatibility, space or other kind of issues, as mentioned in the quotes above. In this article, we'll introduce 3 ways to convert ISO to MKV.

Step 1. Click "ISO" button and browse to add your ISO movie from your computer hard drive or from an external storage device. WinX DVD Ripper for Mac will automatically check the main title. To convert more titles, check them manually.

Tips: copy-protected files are supported as well.

Step 2. On Output Profile window, go to "DVD Backup" and choose "Backup full title to MKV".

Step 3 (optional). Check Intel/AMD/Nvidia (which can boost speed by utilizing GPU hardware acceleration), Use High Quality Engine, Deinterlacing (which is designed to change interlaced video to progressive scanning video), Safe Mode (which is very helpful when the source file is strictly encrypted), and specify how many CPU cores you want to use.

Step 4. Click "Browse" to specify destination folder and tap "RUN" to start conversion from ISO to MKV. Thanks to GPU hardware acceleration, multi-core CPU and Hyper-threading technology, you just need to wait about 5 minutes for the conversion process to complete.

Part 2. How to Convert ISO to MKV with HandBrake

Step 1. Download and install HandBrake. Launch it when you finish installation.

Step 2. Load target ISO file to HandBrake. You can drag it to HandBrake or click "File" option under "Source Selection" to browse and open the ISO file you want to convert to MKV file. Note: HandBrake doesn't support copy-protected files.

Step 3. Choose title and chapters.

Step 4. Choose a MKV preset. HandBrake lists many MKV presets under Matroska category. Simply choose one based on your own needs. Since DVD resolution is 720x480 or 720x576, you're not suggested to choose a MKV preset that is designed with a resolution higher than your original DVD's resolution.

Step 5. Click the "Browse" button at the bottom right to specify which save path and output file name.

Step 6. Click "Start Encode" on the top menu bar and then HandBrake will begin transcoding ISO image to MKV format.

Step 3. When ISO is loaded, you will see titles, video, audio, and subtitle tracks in a tree structure. What you need to do here is to select desired titles and tracks.

Step 4. Set output folder and then click "Make MKV". Then, simply wait for the process to finish.
