How to convert MKV to AC3?
You can convert MKV to AC3 with MConverter in three easy steps:
Choose MKV files from your device
At the top of this page, drag and drop your MKVs. You can also click to select MKV files using your operating system's file picker. Another method is to press the keyboard shortcut Ctrl+V (⌘+V on Mac) to paste an MKV file you have copied to clipboard. Converting a folder with MKV files to AC3 is also supported: simply paste or drag and drop it.
Click or tap on AC3 from the list of target formats
Alternatively, you can use the search field to quickly find the format you need, whether it's AC3 or something else.
Download your AC3 files, after MConverter has finished processing them
There's an option to automatically download the converted AC3 files, so you don't have to press the download icon for each AC3. You may see a share icon as well. Use it to directly share the AC3's with other apps.
About the formats
Video file formats
MKV files are MatrosKa Video files. Like the Russian Matryoshka doll, which contains multiple smaller dolls nested inside each other, the MKV format can contain multiple video, audio, and subtitle tracks inside a single file. This makes it convenient to have one video with a number of audio and subtitle tracks in different languages, all inside a single playable file.
Audio file formats
AC3 files represent the Dolby Digital audio codec, which can include up to 6 audio channels (DD 5.1 surround sound with subwoofer output). Such files are often used for cinemas, DVDs, and game consoles.
