Three kinds of hashtag
A good set mixes tags about this exact post with tags for its wider subject. Here is one set, for a post about a week in Lisbon.
| Group | What it covers | Example |
|---|---|---|
| Specific | Exactly what's in the post | #LisbonTravel #LisbonGuide |
| Topic | The niche and its community | #BudgetTravel #SoloTravel |
| Broad | The wider subject | #Travel |
What hashtags do for your posts
Hashtags tell Instagram what a post is about, and who might want to see it.
Five tags, so make them count
Since December 2025, Instagram allows up to 5 hashtags on a post. That leaves no room for filler, so every tag has to describe the post. The generator gives you fifteen ideas and picks a mix to start with: two specific, two for the topic and one broad.
Specific beats popular
A huge tag like #Love gets new posts all the time, so yours drops out of sight within moments. A tag about exactly what you post reaches fewer people, but they are the ones who care about it. The generator suggests tags by what they mean, not by how many posts use them.
Hashtags work best with a good caption
Instagram also reads the words in your caption, so say plainly what the post is about. Need the words first? Try the free Instagram caption generator. Then schedule the post with Posttyy's Instagram scheduler.
Questions, answered
How does the Instagram hashtag generator work?
Paste your caption or describe your post and press Generate hashtags. AI suggests fifteen hashtags in three groups: specific, topic and broad. The generator picks five to start with. Tap tags to change the pick, then copy it.
How many hashtags should I use on Instagram?
Up to 5. Since December 2025, Instagram allows no more than 5 hashtags on a post. A mix of specific tags and one or two broader ones works well.
Where should I put my hashtags?
At the end of your caption, after your words, so they don't get in the way of what you have to say.
How do I know if a hashtag is banned?
Search for it on Instagram. If Instagram shows no posts, only a few, or a message that recent posts are hidden, leave it out. The generator doesn't suggest tags that only chase likes, such as #followforfollow, which are the ones most often restricted.
Can I use the same hashtags on every post?
You can, but tags that describe each post reach the people who care about that post. Keep one or two tags for your niche, and change the rest to fit the post.
Is the Instagram hashtag generator free?
Yes. It is free, with no login and no sign-up. To keep it free for everyone, each person can generate up to 30 sets of hashtags a day.
What happens to what I type?
Your text is sent to OpenAI, whose AI suggests the hashtags. Posttyy doesn't save your text or the hashtags.
