YouTube Hashtag Extractor
Paste your video title or description below to pull out every hashtag, see which 3 will show above your title, and check whether you've gone past YouTube's real hashtag limit, updated live as you type.
About this tool
Hashtags in a YouTube description work like lightweight topic tags: a viewer can tap one to browse other videos using the same tag, and they give YouTube a small extra signal about what your video covers. This tool reads back exactly what you've written so you can check your hashtags before you publish, not after.
Why the first 3 matter most
YouTube pulls the first 3 hashtags out of your description and displays them directly above your video title, both in search results and on the watch page. That's prime, already-visible real estate, so it's worth being deliberate about which 3 hashtags lead your description rather than letting them fall wherever they happen to land in the text.
The 15-hashtag limit
YouTube stops reading hashtags after the 15th one in a description entirely, anything past that point is silently ignored, not just hidden. If you've packed a description with 20 hashtags hoping for extra reach, the last 5 are doing nothing at all. This tool flags exactly which ones fall outside that limit so you can trim or reorder before you publish.
