Drop a video, see the subtitle tracks it contains with their languages, and save the ones you want as SRT, VTT or ASS. The video never leaves your device. It is read and saved by your browser, so there is no upload, no queue and no copy on a server.
MKV files often carry several subtitle languages, and MP4s from some apps carry one. Extracted, they can be edited, translated or loaded next to another copy of the video.
How to extract subtitles from a video
- Drop your video on the box above. The track reader loads once (about 32 MB).
- Tick the subtitle tracks you want.
- Pick SRT, VTT or ASS and press Extract subtitles.
- Download the files, together as a ZIP when there are several.
Text versus picture subtitles
Text subtitles (SRT, ASS, WebVTT, MP4 timed text) can be saved as text. Subtitles from Blu-ray (PGS) and DVD (VobSub) are stored as pictures, so they can’t become text without character recognition, which this tool doesn’t do. They are shown but can’t be selected.
Captions in the picture
If you see captions but no track is listed, they are burned into the image and can’t be extracted.
Questions
Which files work?
MKV, MP4, MOV, WebM, TS and most other containers.
Why does it download something first?
Browsers can’t read subtitle tracks on their own, so the page loads the open-source ffmpeg once.
What about the language?
Tracks are labeled with their language code when the file has one, and the file names include it.
