How do I convert an MKV file to M4A?

Upload your MKV file, choose M4A as the output format, and select an audio codec: AAC for smaller files or ALAC for lossless quality. Adjust the bitrate if desired, click Convert, and download your M4A file. The video track and subtitles are removed during the process.

Why convert MKV to M4A instead of keeping MKV?

MKV is a versatile video container that often includes multiple audio tracks and subtitles, making it great for video but inconvenient for audio-only listening. M4A is a compact audio format with broad support on Apple devices, iTunes, and car stereos. Converting to M4A strips away the video, dramatically reducing file size while keeping the audio track you want.

Does converting MKV to M4A preserve the original audio quality?

If the source audio is already AAC, we can copy it without re-encoding, making the conversion lossless. For other codecs like AC3 or DTS, we transcode to AAC at up to 320 kbps, which is perceptually transparent. If you need bit-perfect preservation, choose ALAC; the file will be larger but every bit of the original audio is retained.
