Hashtag Generator
Get relevant, high-reach hashtags tailored to your topic and platform.
The right hashtags put your post in front of people who don't follow you yet — the wrong ones bury it. This free hashtag generator takes a single line about your topic and returns relevant, high-reach hashtags tailored to the platform you're posting on, from Instagram hashtags to TikTok and X.
Instead of recycling the same generic tags on every post, you get a fresh, focused set that blends broad discovery terms with tighter niche ones — the combination that actually helps new audiences find your content. Choose how many you want, from a tidy three to a full thirty.
Copy the whole list with one click or cherry-pick the tags that fit, then paste them into your caption or first comment. When you want to plan and publish those posts across every network from one place, PostJay has you covered.
Frequently asked questions
How does the hashtag generator find hashtags?
Describe your post, niche, or product, choose your platform, and set how many hashtags you want. The generator returns a focused mix of relevant tags — from broad reach terms to tighter niche ones — that match what people actually search for on that platform.
How many hashtags should I use?
It depends on the platform. Instagram and TikTok do well with a fuller set of niche-relevant tags, while X, LinkedIn and Bluesky reward a tighter handful. You can request anywhere from 3 to 30 here, then trim to taste before posting.
Are these hashtags free to use?
Yes — generate hashtags for free, no account needed. Anonymous visitors get a few generations per day; sign up for a free PostJay account to lift the daily limit.
How do I add the hashtags to my post?
Hit "Copy all" to grab the full space-separated list, then paste it into your caption or first comment. You can also pick individual tags from the list if you only want a subset.
