How to convert MKV to AAC?
You can convert MKV to AAC 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 AAC is also supported: simply paste or drag and drop it.
Click or tap on AAC from the list of target formats
Alternatively, you can use the search field to quickly find the format you need, whether it's AAC or something else.
Download your AAC files, after MConverter has finished processing them
There's an option to automatically download the converted AAC files, so you don't have to press the download icon for each AAC. You may see a share icon as well. Use it to directly share the AACs 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
Fraunhofer Institute, Nokia, Dolby, AT&T, Sony and others
AAC files are audio files using Advanced Audio Coding compression. AAC is a lossy format, meaning the audio quality remains almost the same as the original source. The slight loss leads to the audio files taking up less space, which makes them ideal for music streaming or when bandwidth is limited. AAC is superior to MP3 for handling frequencies above 16 kHz. The encoding efficiency for transient and stationary signals is also better when compared to MP3.
Common questions about converting MKV to AAC
Can I convert MKV to AAC in bulk?
Yes, MConverter supports batch converting of multiple MKVs to AACs simultaneously. You can even drag and drop folders containing MKVs to convert to AAC. Pasting MKV files and folders copied in the clipboard also works: use Ctrl+V.
