Common questions
Does this keep the video?
No — only the audio track is extracted and saved as MP3. To keep the video, convert MKV to MP4 instead.
My MKV has several audio tracks — which one?
The primary audio track is extracted. If you need a specific alternate track, let us know via support.
Will quality drop?
We re-encode at a high bitrate, so the MP3 matches the source audio to the ear. For lossless, extract to FLAC or WAV.
Is there a file size limit?
Free users get up to 25 MB without an account; Pro raises it to 500 MB per file with 3,000 credits a month.
