Extract Subtitles from a Video

Many MKV and MP4 files carry subtitle tracks inside them. Save each text track as its own file to edit, translate or use elsewhere. Picture-based subtitles (DVD, Blu-ray) cannot be converted to text.

Why use Aback Video for this

  • All tracks at once

    Files with several languages give you one subtitle file per track.

  • Language names

    Tracks are named with their language tag, such as eng or hin, when the video includes one.

  • Quick

    Subtitles are read without decoding the video, so it is fast even on large files.

  • Private

    The video is read in your browser and never uploaded.

Frequently asked questions

Why does it say no subtitle tracks were found?

The video has no embedded subtitle track, or its subtitles are burned into the picture. Burned-in text cannot be extracted; Auto Subtitles can create new subtitles from the speech instead.

Can it extract DVD or Blu-ray subtitles?

No. Those are pictures of text (VobSub and PGS), not text, so they cannot be converted to SRT here.

Which format should I choose?

SRT works with most players and editors. VTT is for web players. ASS keeps styling such as positions and colours if the track has them.

Is my video uploaded?

No. The tracks are read on your device with FFmpeg in WebAssembly.

How can I see what tracks a file has first?

Video Info lists every stream, including subtitle tracks and their languages.

Does it work on phones?

Yes, though MKV files from a phone's Files app may need to be fully downloaded first.
