How DownSub turns captions into files
A subtitle downloader does not create captions from nothing. It reads available caption tracks, cleans them up, and exports them in formats that are easier to use.
The subtitle workflow
The process is intentionally simple: paste a link, choose an available track, and download the file you need.
Paste a public video URL
Start with a link to a supported public video. DownSub checks whether the source exposes caption tracks for that URL.
Choose language and format
Select an available caption language, then choose SRT, VTT, or TXT depending on whether you need timed subtitles or readable transcript text.
Download the prepared file
When captions are available, DownSub formats the track for your browser download or lets you copy the transcript text.
SRT vs VTT vs TXT
Choose the output that matches the job.
SubRip Subtitle
The broad compatibility choice for editors, desktop media players, course platforms, and review workflows. It includes numbered timed captions.
WebVTT
A web-friendly format for HTML5 video tracks. It can preserve timing and support cues that fit browser video players.
Plain transcript
A clean text transcript without timing data. Best for reading, quoting with permission, searching, notes, and summaries.
Why some videos cannot be processed
The creator did not add manual captions and auto captions are unavailable.
The video is private, deleted, region restricted, age restricted, or behind a login.
The platform changed how it exposes caption tracks.
The selected language is not available for that video.
Responsible use
Use subtitles for videos you own, have permission to use, or where your use is lawful and allowed by the platform terms. DownSub is not intended to bypass restrictions or redistribute copyrighted transcripts.
Workflow FAQ
Does DownSub create subtitles from audio?
No. DownSub is positioned as a subtitle downloader for available caption tracks, not a transcription engine that creates new captions from audio.
Why does DownSub check captions before format selection?
Language and format options depend on the caption tracks exposed by the source video. If no captions are available, there may be nothing to export.
Can I copy a transcript instead of downloading a file?
Yes. The tool includes a copy action for transcript use cases where readable text is more useful than timed captions.
