How to convert MP3 to MKV?
You can convert MP3 to MKV with MConverter in three easy steps:
Choose MP3 files from your device
At the top of this page, drag and drop your MP3's. You can also click to select MP3 files using your operating system's file picker. Another method is to press the keyboard shortcut Ctrl+V (⌘+V on Mac) to paste an MP3 file you have copied to clipboard. Converting a folder with MP3 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. On desktop platforms, you can download the MKV files to a different folder by clicking on SAVE TO... You may see a share icon as well. Use it to directly share the MKVs with other apps.
About the formats
Audio file formats
MPEG (Moving Picture Experts Group)
MP3 is a commonly used audio format. The audio data is compressed inside the file, which is why MP3 files take up less space than WAV, for example. Even though the audio is compressed, the quality is still good enough for most personal use cases.
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.
