MKV to AIFF Converter

Convert MKV files to AIFF. Free, without uploading.

This tool converts MKV files to AIFF. MKV (Matroska) is a flexible container that can hold several audio and subtitle tracks. It is common on computers, but phones and TVs don’t always play it.

AIFF is Apple’s uncompressed audio format, the Mac counterpart of WAV. Only the audio of the MKV video is kept and saved as AIFF; the picture is dropped. AIFF is lossless, so the audio keeps the quality it has in the MKV file.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the MKV video, drag it in, or paste its link.
2. Choose the audio quality; optionally enter a start and end time.
3. Press "Convert" and download the AIFF file.
