Instagram Hashtag Generator FAQ
How many hashtags should I use on Instagram posts and Reels?
Since December 2025 Instagram allows up to 5 hashtags per post. Pick the 3 to 5 that fit your post best, and use the checker on this page to confirm you are within the limit.
What's the difference between broad, niche, and branded hashtags?
Broad hashtags (#travel, #food) have millions of posts, so a new post drops out of view within minutes. Niche hashtags (#veganmealprep, #minimalistliving) reach fewer people who care more about the topic. Branded hashtags are your own, so followers can find and use them.
Can I save and organize hashtag sets for different content types?
Yes, in the PostNext app. Save a set as a hashtag group (fitness, food, travel and so on) and add it to a post from the composer.
Do Instagram hashtags actually increase reach and engagement?
They help Instagram understand your post and show it in search and on hashtag pages. Adam Mosseri, who runs Instagram, has said hashtags do not increase reach on their own, so treat them as labels for the post rather than a reach lever.
Is the Instagram hashtag generator completely free?
Generating needs a PostNext account, which includes monthly AI credits. In the app you can also save sets as hashtag groups and add them from the composer. The hashtag checker on this page is free and works in your browser.
