Extract audio from MKV as MP3

About MKV to MP3

MKV files often pack high-quality video and audio, but sometimes you just want the soundtrack, dialogue, or music as a standalone file. Extracting an MP3 gives you a small, playable audio clip you can take anywhere. This tool pulls the audio from your MKV and saves it as MP3.

Upload your .mkv video and the converter separates the audio and encodes it as a universal MP3. It runs in your browser, is free, and never adds a watermark or asks for signup. Your file is processed only for the extraction and isn't stored, so your content stays private.

FAQ

MKV can hold several audio tracks, which one is used?

The tool extracts the audio present in the file. For files with multiple tracks, it generally takes the main one into your MP3.

Does extracting affect the MKV file?

No. A new MP3 is created and your original MKV stays unchanged.

What quality should I expect?

MP3 is compressed, so it isn't lossless, but it remains close to the source and great for everyday listening.

Can I use MKV to MP3 on mobile?

Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
