An Instagram hashtag generator suggests hashtags for a post from a description of what it is about. Describe the post, the product, the place and the audience, and this one returns a list of hashtags mixing broad, niche and local tags, in the language of your description. The list is written by an AI language model on Lukky's backend, free and with no sign-up. Treat it as a starting list: remove what does not fit and keep the tags your audience actually follows.
How do you use the hashtag generator?
- Describe the post in the field: what it shows, what you sell, where you are, who it is for. "Christmas giveaway for a handmade jewelry brand in Austin, prize: a silver necklace" is enough. Fifteen characters minimum.
- Generate. The hashtags appear in a few seconds, ready to copy.
- Copy the list, paste it into the caption or the first comment, and delete the tags that do not fit the post. "Start again" gives a new list from a changed description.
How many hashtags should you use?
Instagram allows up to 30 hashtags per post, and its own advice to creators is to use 3 to 5 relevant ones. Between those two figures, the useful rule is that every tag should describe the post to someone who searches or follows that tag. Ten tags that fit beat thirty that do not, and a tag unrelated to the image tells Instagram nothing useful about who should see it.
The generator returns a list you can trim rather than a list you have to complete. Keep the specific tags, cut the generic ones that any post could carry, and never paste the same block under every post: repetition is the behavior Instagram treats as spam.
How do you pick hashtags that work?
- Mix sizes. A few broad tags with millions of posts, more mid-sized tags with tens or hundreds of thousands, and niche tags where your post can stay on top for days.
- Describe the post, not the goal. A tag names the subject, the style, the place; tags asking for likes or follows attract accounts that engage with nothing.
- Add the place when the audience is local: the city, the neighborhood, the event.
- Use one brand tag consistently, so your customers' posts collect in one place.
- Add one giveaway tag on a giveaway post, no more: "giveaway" is one of the most crowded tags on Instagram, and it draws contest hunters rather than customers.
- Check a tag before using it. A tag can be restricted or hidden; a search on Instagram shows in a second whether recent posts appear.
Hashtags for a giveaway post
For a giveaway, the hashtags come last: the caption and the rules matter more. The Instagram caption generator writes the caption from the same description, and the engagement rate calculator tells you how your account performs before and after. When the giveaway ends, the Lukky app draws the winner from the comments through the official Meta authorization, with a public certificate your entrants can check; more than 2.5 million draws have been run with it.
FAQ
- How many hashtags does Instagram allow?
- Thirty per post. Instagram's own advice to creators is 3 to 5 relevant hashtags; a longer list is fine if every tag actually describes the post.
- Should hashtags go in the caption or the first comment?
- Either works for reach. In the caption, they are visible with the text; in the first comment, the caption stays clean. Pick one and stay consistent.
- Are the generated hashtags checked against Instagram?
- No. The list comes from an AI language model that describes your post; it does not query Instagram. Search a tag in Instagram before using it if you want to confirm it is active.
- In what language are the hashtags?
- In the language of your description, with the English tags that are common in your niche. A description in Spanish returns Spanish tags.
- Is the generator free?
- Yes, without sign-up and without limit. The list is yours to edit and use.
