How to convert AAC to MKV?
You can convert AAC to MKV with MConverter in three easy steps:
Choose AAC files from your device
At the top of this page, drag and drop your AACs. You can also click to select AAC files using your operating system's file picker. Another method is to press the keyboard shortcut Ctrl+V (⌘+V on Mac) to paste an AAC file you have copied to clipboard. Converting a folder with AAC files to MKV is also supported: simply paste or drag and drop it.
Click or tap on MKV from the list of target formats
Alternatively, you can use the search field to quickly find the format you need, whether it's MKV or something else.
Download your MKV files, after MConverter has finished processing them
There's an option to automatically download the converted MKV files, so you don't have to press the download icon for each MKV. You may see a share icon as well. Use it to directly share the MKVs with other apps.
About the formats
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.
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.
