I have uploaded the video on YouTubeand added the subtitles but the users don't realize that they can turn them on. I know there is particular URL parameter for embedded player, but it doesn't work for youtube.com itself. I have tried:


and it returns the page in German, but does not turn the subtitles on.

How can I force YouTube to use subtitles on youtube.com itself?

    For others researching the same: right now, only &cc_load_policy=1 seems to work, as it turns the CC on, but no language can be set... pity, it's so convenient to share links properly – brasofilo Feb 26 '16 at 2:18

The only way I found is changing the URI from


to this pattern

"https://www.youtube-nocookie.com/embed/" + VIDEO_ID + "?hl=" LANG_CODE

If hl= doesn't work (on some cases doesn't seems to work) try cc_load_policy=1&cc_lang_pref=.

On bash/Linux you can just copy the URI with that structure and then run this command (Spanish code hardcoded) to transform clipboard content (you can make an alias):

xclip -selection c -o | echo "$(cat -)?&hl=es-419" | sed "s|youtube.com/watch?v=|youtube-nocookie.com/embed/|1" | xclip -selection c

You can list the available subtitles ISO 639-1 language codes with youtube-dl:

youtube-dl --list-subs "{video_id or url}"


  • the video will cover the complete screen... which might be good thing to stop procrastinating with related videos :)
  • It seems that doesn't work with automatic generated captions.
  • This seems to change the UI language, but doesn't show the subtitles. – Tin Man Apr 19 '19 at 22:35
  • But adding &cc_lang_pref=de&cc_load_policy=1 (e.g. youtube-nocookie.com/embed/…) seems to work! – Tin Man Apr 19 '19 at 22:37

I've found out how to do it.



to your video url, and subtitles will be on youtube.com by default. Of course, you need to use your language instead of de.

    that was a dirty hack with limited lifetime :D – eviltnan Sep 18 '15 at 12:06

This solution effects your videos on the platform aswell as when you embed it.

Go to "Youtube Studio" and click on the video where you want to force subtitles.

Scroll down to tags. Add yt:cc=on will force subtitles. Add cc_lang_pref=en to select preferred subtitles. enter image description here

Make sure that you have published the preferred subtitles as extra language, even if you just want to use the auto-generated ones.

  • Excellent, this works! So YouTube never actually stopped using yt:cc=on ... but they started to require cc_lang_pref=en or whatever language you like on top – ChrisB May 28 at 2:45
