No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
MKA does not play in Apple's players, in most browsers or on many phones. FLAC keeps full quality at about half the size of WAV. An MKA file usually holds Almost any audio codec, with chapters and tags. MKA is at home in audio with chapters, several tracks or codecs other formats do not hold; FLAC is the usual choice for archiving music at full quality.
The defaults suit most files. Under Options you can trim the start and end.
The conversion uses your browser's own video and audio codecs (WebCodecs), with hardware acceleration where the device has it; the file is read from disk as it goes and can be up to 2 GB. Where the browser lacks a codec, the page falls back to the compatibility engine.
MKA is the audio-only variant of the Matroska container, the same open container as MKV. It can hold nearly any audio codec together with chapters, tags and cover art, and is used for audiobooks, concerts and multichannel recordings.
