Questions
- Which MKV soundtracks work?
- AAC, Opus, Vorbis, MP3 and FLAC — what screen recorders and most downloads use. Film soundtracks in Dolby Digital (AC-3) or DTS many browsers can’t decode; then the tool says the conversion didn’t work.
- My MKV has several audio tracks — which one is converted?
- Only one track becomes the MP3 — the file’s main soundtrack. Additional tracks, such as other languages or commentary, are skipped.
- Is a long recording a problem?
- Not on a computer: the file is read piece by piece, so long recordings such as a full lecture work too. The progress bar shows how far along it is.
- Are my files uploaded anywhere?
- Your file never leaves your device. It is converted right here, in your browser — nothing is uploaded.
