How do I extract subtitles from an MKV file?

Choose the MKV file above. The tool lists every subtitle track with its language, and you download the one you want as SRT, VTT or ASS. You don't need MKVToolNix or the mkvextract command.

Can I extract subtitles from an MP4?

Yes, when the MP4 has a subtitle track. MP4, M4V and MOV files store subtitles as MP4 text (mov_text) or WebVTT, and both can be saved as SRT or VTT.

Can I extract burned-in subtitles?

No. Burned-in (hardcoded) subtitles are part of the picture, so there is no subtitle file inside the video to extract. Caption X can make new subtitles from the video's audio instead.

Why can't some subtitle tracks be saved as SRT?

Blu-ray (PGS) and DVD (VobSub) subtitles are stored as pictures of the text, not as text. For a PGS track, choose Convert to SRT and the text is read with OCR. VobSub tracks are listed so you know they are there.

Which file should I download, SRT, VTT or ASS?

SRT works almost everywhere, including VLC, Plex, YouTube, Premiere Pro and DaVinci Resolve. VTT is for web video players. ASS keeps the fonts, colours and positions of anime and fansub subtitles, and is offered when the track was made in ASS.

Is my video uploaded?

No. The video is read in your browser and stays on your device. It is read a piece at a time rather than all at once, so large videos work too.

What It Extracts

Which subtitles can be extracted

A video file can carry subtitles in a few different ways. Here is what this tool does with each.

Text subtitles

SRT (SubRip), ASS, SSA and WebVTT tracks in MKV and WebM files, and MP4 text and WebVTT tracks in MP4, M4V and MOV files. These download as SRT, VTT or ASS.

Picture subtitles

PGS subtitles from Blu-ray and VobSub subtitles from DVD are images of the text. PGS tracks can be converted to SRT with OCR; VobSub tracks are listed with their language.

Burned-in subtitles

Subtitles drawn into the picture aren't stored as a track at all. For those videos, Caption X can make new subtitles from the audio.

MKV Files

Extract subtitles from MKV without mkvextract

MKV files often hold several subtitle tracks: one per language, plus forced tracks that only translate signs and foreign dialogue. The usual way to get one out is to install MKVToolNix and run mkvextract with the track number. Here you choose the file, see every track with its language, and download the one you need.

Files are named the way media players look for them, such as Movie.eng.srt or Movie.eng.forced.srt, so VLC, Plex and Jellyfin pick them up when you put them next to the video.
