How to convert MKV to FLAC?
You can convert MKV to FLAC 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 FLAC is also supported: simply paste or drag and drop it.

Download your FLAC files, after MConverter has finished processing them
There's an option to automatically download the converted FLAC files, so you don't have to press the download icon for each FLAC. On desktop platforms, you can download the FLAC files to a different folder by clicking on SAVE TO... You may see a share icon as well. Use it to directly share the FLACs 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
FLAC, or Free Lossless Audio Codec, files contain digital audio. FLAC files utilize lossless quality, meaning that there is no loss of any original sound data. When compared to MP3 (lossy audio format), FLAC files are generally larger. Nonetheless, FLAC’s lossless compression algorithm can reduce audio by up to 70%, and still be able to reproduce the original audio afterwards. The format is royalty-free.
