How it works

  1. 1

    Upload your MKV

    Up to 300MB and 90 minutes long.

  2. 2

    Audio is extracted automatically

    The first audio track is pulled out and transcribed — the video file itself is never stored.

  3. 3

    Copy or download

    The transcript appears as editable text, ready to copy or download.

Why use it

No separate extraction step

Upload the MKV directly — there's no need to pull the audio out yourself first.

Works on large files

Handles files up to 100MB without choking.

Clear errors, not silent failures

A file with no audio track gets a clear error instead of an empty result.

Frequently asked questions

My MKV has multiple audio tracks — which one gets transcribed?

The first audio track in the file. If the track you need isn't the default one, select the correct track in a media player and re-export the file before uploading.

Does it work if my MKV has no audio track?

No — it needs an audio track to transcribe. You'll get a clear error if the file has none.

Does this only work with MKV files?

No — it also accepts MP4, WEBM, MOV, AVI, and 3GP. This page is tuned for MKV specifically since it's common for downloaded videos, rips, and recordings with multiple audio or subtitle tracks bundled in.

Is it free?

Yes. It's free with no account required, limited to a fair-use number of transcriptions per hour.

What's the file size and length limit?

Up to 300MB and 90 minutes per file on the free tier.

Does it upload my video anywhere permanently?

No. The audio track is extracted in a temporary file just long enough to transcribe it, then deleted immediately. Your video is never stored.
