Check where DownSub can download subtitles before you paste a link. Use a public video URL from a supported site and save available captions as SRT, VTT, or TXT.
Every site below has been checked against live public URLs that returned real subtitle cues. A specific video can still fail if it has no captions, is private, needs a login, is region-blocked, or the platform changes how it exposes captions.
Copy a public video link from one of the sites above, paste it below, and download the available subtitle tracks.
DownSub only surfaces captions that a source already makes available for a public video.
Private videos, paywalled content, DRM, and login-only pages are outside its intended use.
Some platforms expose full timed caption tracks; others may only offer limited transcript data.
These video sources are listed because they worked with public caption tracks during testing.
Manual and auto-generated caption tracks can be downloaded whenever the public video exposes them.
Public Vimeo videos that carry a caption file can be exported as SRT, VTT, or TXT.
TED pages with transcripts and captions attached support clean subtitle exports.
Public TubiTV titles can work when a caption track is available from the page.
Public Weverse media can work when the video exposes captions through an accessible player.
Public TV Naver videos can be downloaded when the page includes timed captions.
See which supported sites DownSub works with for online subtitle downloads. Use public video links from YouTube, Vimeo, TED, TubiTV, Weverse, and TV Naver — each source has been tested against real public URLs and returned genuine subtitle cues.

Being on this list doesn’t guarantee every single video will return a file. A specific video can still fail if it has no captions at all, is private, requires login, is region-blocked, or the platform changes how it exposes captions. See how it works for the full extraction process, and the FAQ for the most common failure reasons.
Once you’ve confirmed your source is supported, paste the link on the DownSub home page and choose SRT, VTT, or TXT — see the subtitle formats guide if you’re not sure which one you need.
This list reflects platforms that expose public caption data in a way DownSub can reliably read. Coverage can change if a platform updates its player or captioning system, so the supported sites list is reviewed periodically rather than fixed permanently.
