Hashtag Generator

Hashtag Generator: free, instant and private. Instagram indexes posts on 3–5 focused hashtags — the rest are reach tags, so 10–15 total is a sensible ceiling.

How the Hashtag Generator works

The Hashtag Generator takes Caption or topic, Platform, How many hashtags, Niche word to seed (optional) and returns the answer instantly — no button to hunt for, no page reload. Instagram indexes posts on 3–5 focused hashtags — the rest are reach tags, so 10–15 total is a sensible ceiling. LinkedIn treats more than about 5 as spam and X ranks plain text above tags, which is why the platform choice reshapes the whole list.

Enter your own numbers to replace the example values; the result panel updates as you type. Everything runs in this single page, so nothing you enter leaves your device.
