Smart MKV audio extraction
Converter App pulls the default audio track from your MKV and saves it as a clean MP3, dropping video and subtitles. For multi-track files, set your desired language as the default in the MKV or choose it in Expert Settings before converting.
Pick the right MP3 quality
Choose Auto for a smart balance of size and clarity; for speech use 64 to 96 kbps mono, for music 160 to 192 kbps stereo, and 320 kbps for the least compression. Open Expert Settings if you want to fine-tune bitrate and channels.
Free to use
Converter App is 100% free to use. No sign-up, no watermarks, and no daily limits beyond fair use.
Handles large videos
Upload MKV files over 1 GB with confidence; we process one video at a time and you can start the next as soon as your download begins. If your connection is unstable, keep this tab open until the MP3 is ready.

Enjoy a clean interface with clear progress and MP3s that play everywhere. There are no usage caps, so convert as many MKVs as you like.
Privacy first
Your files are processed securely and removed shortly after the conversion completes. Everything is automated; no one looks at your content.
