Convert MKA to MP3.
MKA is the audio-only side of Matroska: flexible, but barely supported by everyday players. Convert it to MP3 that plays on every phone, car stereo and app.

Matroska, minus the video
Most people meet Matroska as .mkv video files. .mka is the same container carrying audio only, often used for multi-track soundtracks, audiobooks or extracted audio. It's a capable format, but that flexibility comes at the cost of compatibility: hand an MKA to a phone or a car stereo and it usually shrugs. MP3 just works.

MKA to MP3: re-encoded
MP3 is a compressed, lossy audio format, so this re-encodes the sound and the file gets smaller. Every lossy re-encode sheds a little quality, so convert from the best source you have rather than chaining conversions.

Common questions
What is an MKA file?+
MKA is the Matroska audio container. The audio-only cousin of the MKV video format. It's powerful and open, capable of holding multiple tracks, but most consumer players and phones don't recognise it. MP3 is the opposite: less flexible, universally supported.
Is it free?+
Yes. Convert MKA to MP3 free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour. Files never touch a third-party converter.
What about quality?+
We re-encode at a high MP3 bitrate, so for music and speech the result is faithful to the source.
