It breaks your title or topic into its meaningful words and phrases, joins each into hashtag form, and orders them from most specific (the full topic, your niche) to broadest (single words, then a few evergreen tags like #tutorial). The first three are the ones YouTube will display, so they're the ones that describe the video most precisely. Everything runs in your browser — nothing is sent anywhere.
YouTube Hashtag Generator
Turn a video title or topic into a ready-to-paste set of hashtags — ordered so the three YouTube displays above your title are the ones that matter.
How this tool builds the list
Frequently asked questions
How many hashtags should a YouTube video have?
Three to five well-chosen ones. YouTube displays the first three above the title (unless the title itself contains hashtags, in which case those win), and it ignores every hashtag on a video that has more than 15 — so stuffing them in is actively harmful, not just useless. This tool never gives you more than 15 and puts the three most specific ones first.
Where do hashtags go — the title or the description?
Either works; the description is the usual choice because it keeps the title clean. If you put any hashtag in the title, YouTube shows those instead of the first three from the description. A common pattern is one hashtag in the title for the exact topic and the rest at the very end of the description.
Do hashtags actually help a video get found?
Modestly. Each hashtag is a clickable link to a page of every video using it, and YouTube uses them as a light relevance signal for search and for grouping Shorts. They matter more for Shorts and for trending topics than for evergreen long-form videos, where the title and description do the heavy lifting. They never replace a good title.
Why are some words from my title missing?
Hashtags can't contain spaces, punctuation, or common filler words, so "how to", "the", "for", and similar are dropped and multi-word phrases are joined together (#homeworkout). Anything that would be a single letter or just a number is also skipped, since those hashtag pages are too broad to send anyone relevant.
