Instagram hashtag generator
Generate 30 targeted Instagram hashtags for any niche, split by size (small/medium/large).
about the instagram hashtag generator
Instagram hashtags are still one of the best free ways to reach people who don't follow you yet — but only if you use the right mix. Stuffing 30 of the biggest, most competitive tags buries your post instantly. This free generator gives you a balanced set for any niche, split by size so you get a real shot at discovery.
The winning strategy is a pyramid: a few large hashtags (1M+ posts) for reach, more medium tags (100K-1M) where you can actually rank for a while, and several small, specific tags (under 100K) where your post can sit at the top of the feed and pull in a tightly relevant audience. This tool generates all three tiers for you.
Enter your topic and get 30 targeted hashtags free, no sign-up. When you're ready to schedule the post itself — with the hashtags dropped neatly into the first comment — PostAI's Instagram scheduler handles it.

How many hashtags should I use on Instagram?
Instagram allows up to 30 hashtags per post, but a focused mix of 8-15 relevant tags across different sizes typically outperforms maxing out with generic ones. Quality and relevance beat quantity.
Should I put hashtags in the caption or the first comment?
Either works for reach, but many creators prefer the first comment for a cleaner caption. PostAI's Instagram scheduler can automatically post your hashtags as the first comment.
