What it does

What RecurPost's Instagram Hashtag Generator Does

RecurPost’s Instagram Hashtag Generator reads a short keyword or content description and returns a ready-to-use set of Instagram hashtags. RecurPost’s generator blends three kinds of tags into every set: discovery, niche, and engagement.

Broad discovery tags are commonly used across a niche to increase visibility. Niche tags tie directly to the post’s specific topic. Engagement tags are picked to prompt replies and saves rather than reach alone.

This streamlined process is particularly useful for managing hashtag sets across multiple client accounts, without logging into anything beyond RecurPost’s Instagram Hashtag Generator.

Step by step

How to Generate Instagram Hashtags in Four Steps

Using RecurPost’s Instagram Hashtag Generator takes four steps, and all four run free in the browser with no sign-up.

01

Describe the post

Type a short description or keyword for the post. RecurPost needs only a phrase, not a full caption — the field’s own example is “B2B SaaS marketing strategy.”

02

Open Optional fields

Optional fields adds a keyword to carry into the set, a language (English, French, Spanish, German, or Italian), and a tone. Twenty-two tone presets are available, from Professional and Informative to Witty, Bold, and Urgent.

03

Generate the list

RecurPost returns an Instagram-ready mix of discovery, niche, and engagement tags in the results box below the form.

04

Copy the tags

One button copies the whole set out of the results box. Paste it into the Instagram caption or the first comment, then publish or schedule the post.

For instance, a freelance social media manager batch-scheduling five client Instagram accounts on a Sunday night can generate a fresh tag set for each post. They can do this without logging into anything beyond RecurPost’s Instagram Hashtag Generator.

Not transferable

Where an Instagram Hashtag Set Does Not Transfer

The Instagram Hashtag Generator is one of eight free tools published alongside RecurPost’s social media scheduler, each built to prepare a post before it is scheduled. RecurPost runs a matching hashtag generator for nine other platforms — Facebook, TikTok, X, YouTube, Pinterest, Threads, LinkedIn, Bluesky, and Google Business Profile — because a set built to Instagram’s rules rarely suits another network unchanged. The four below differ from Instagram most sharply. Pinterest and Bluesky run their own generators as well, and the Hashtag Generator hub lists all ten side by side with the limit each one works to.

TikTok reads only the first five hashtags in a caption and ignores the rest, so the TikTok generator fills those five slots with a broad tag, community tags, and a trend tag rather than reusing an Instagram mix.

Threads applies a single topic tag per post, and every other hash-prefixed word is plain text. The Threads generator returns candidates to choose one from rather than a set to paste.

YouTube shows the first three hashtags from a video description above the title, and ignores every tag once title and description together carry roughly sixty. The YouTube generator writes for that description field, not for Studio’s separate Tags field.

Google Business Profile

A Google Business Profile post does not turn hashtags into links, so tag count stops being the useful lever. The GBP generator puts its output into the post copy, and an Instagram tag block adds nothing to it.

Checking the destination before reusing a set fits any agency or freelancer running two or more platforms per client. A freelancer who posts to Instagram alone for every client can stay on this page and skip the rest.

From tags to schedule

Getting Hashtags Into a Scheduled RecurPost Post

RecurPost’s Instagram Hashtag Generator runs separately from the scheduler, so moving a set into a post is a manual copy-paste step. Copy the generated tags straight into RecurPost’s Instagram composer alongside the caption, or save them to a RecurPost Bag of Tags first if the same client reuses a set across several posts. RecurPost’s Instagram scheduler then holds the queue and publishes the post at its scheduled time.

For example, an agency scheduling a client’s Reel and a static carousel for the same week can generate two different hashtag mixes. One set can be tailored to the Reel, while the other is created for the carousel. The agency can then bulk-schedule both through RecurPost’s scheduling and publishing tools in a single sitting. RecurPost’s AI content tools can also draft the caption, so the hashtag set and the caption come from the same workflow instead of two separate tabs.

No credit card. One composer covers a full client mix, so a generated hashtag set moves into a scheduled post rather than into an intermediate spreadsheet.

The boundary

How Many Instagram Hashtags to Use, and What Mix

Where a niche-heavy mix fits

Instagram caps a post or Reel at five hashtags, so every one of the five has to earn its place. Suppose one agency runs a twelve-account client roster. Three of those accounts belong to small studios with fewer than 5,000 followers each. The three studio accounts do better with a niche-heavy mix, because niche tags are specific enough to place a post within a smaller, more relevant hashtag community instead of competing with millions of generic posts.

Where a discovery-heavy mix fits

Two of the accounts in that same roster belong to larger, multi-location brands with an established following. Those accounts can lean on broader discovery tags, because their existing engagement already helps a post surface inside a busier hashtag feed.

Where one list does not work

Applying the same hashtag list to all five accounts fails to account for each account’s audience and niche. A studio account gains little from a hashtag with ten million posts already attached to it, and a large brand account gains little from a hashtag so narrow that almost nobody searches it. Generate a fresh set per account rather than reusing one list across a roster.

Three jobs

Hashtags Are Not a Caption or a Title

Hashtags tag the post for discovery. That is this tool’s only job.

The caption carries the body text the hashtags sit under. RecurPost’s Instagram post generator writes that one.

A title heads the content above both. RecurPost’s title generator handles those.

RecurPost splits the three jobs across separate free tools, each running under the same no-sign-up rule, and you can reach the full set from RecurPost’s free tools hub.

How does RecurPost's Instagram Hashtag Generator work?

RecurPost’s Instagram Hashtag Generator reads a keyword or short content description and generates a set of relevant Instagram hashtags. The results combine discovery, niche, and engagement tags. RecurPost’s generator runs in the browser with no account required.

Instagram caps every post and Reel at five hashtags, a limit it introduced in December 2025. RecurPost’s generator returns a ready-to-use mix of discovery, niche, and engagement tags, so you can pick a niche-heavy five for a small account or a discovery-heavy five for a larger one.

Yes. RecurPost’s Instagram Hashtag Generator is free with no sign-up or payment required. The generator works directly in the browser and doesn’t require a RecurPost account.

RecurPost runs a separate hashtag generator for each of nine other platforms: Facebook, TikTok, X, YouTube, Pinterest, Threads, LinkedIn, Bluesky, and Google Business Profile. Each version is tuned to that platform’s own hashtag norms rather than reusing the Instagram mix.

RecurPost allows you to copy the generated hashtag set into its Instagram composer alongside the caption, then schedule or bulk-schedule the post as usual. It also lets you save the frequently reused hashtag sets to a RecurPost Bag of Tags, so the same mix is one click away on the next post for that account.
