What this free hashtag generator does
A hashtag generator helps you choose the words that label your post, so people who follow or search those topics can find it. This free online tool takes your topic or keywords, then builds a set of hashtags that mixes broad tags, medium tags and niche tags. It adds common variants of your keywords, tags from a built-in list for 27 niches, optional local and brand tags, and sensible defaults for Instagram, TikTok, X, LinkedIn, YouTube, Facebook, Pinterest and Threads.
It also does a few things most generators skip. It writes tags in CamelCase for accessibility, lets you click out any tag you do not like, shows the mix as a live bar chart, copies the set in four formats including the Instagram first comment style, and includes a cleaner that fixes a messy list of tags in one step. It is honest about its limits: it does not claim to know live post counts or trends, because a browser tool cannot read them.
How to use the hashtag generator
- Enter your topic. One or two keywords work best, such as coffee or morning routine. Separate several topics with commas.
- Pick the platform. The tool sets a sensible number of tags for it.
- Choose a niche or leave it on detect. The tool matches your words to a niche list.
- Set the reach mix. Balanced works for most posts. Choose niche for a small account and reach for a big account.
- Add a location or brand tag. Both are optional.
- Generate, trim and copy. Click tags to leave them out, press Generate again for new combinations, then copy.
How to choose the right mix of hashtags
A hashtag works like a shelf in a very large shop. A broad tag such as #coffee is a shelf with millions of items, so your post is quickly buried. A niche tag such as #PourOverCoffee is a smaller shelf with fewer posts and a more interested audience, so your post stays visible longer. Most accounts do best with all three levels: a few broad tags to signal the general topic, several medium tags for your subject, and some niche tags for the exact angle.
| Level | Example | Audience | Competition | Share of a typical set |
|---|---|---|---|---|
| Broad | #coffee | Very large | Very high | 10% to 25% |
| Medium | #coffeelover, #homebarista | Large and focused | High | 30% to 40% |
| Niche | #PourOverCoffee, #AustinCoffee | Small and engaged | Lower | 35% to 60% |
A new or small account should lean on niche tags, because broad tags will bury the post. A large account can use more medium and broad tags since its posts begin with more engagement. The Reach mix option sets these shares for you.
Hashtags on each platform
| Platform | How many | Where to put them | Notes |
|---|---|---|---|
| Up to 30 allowed. A few focused tags are advised | Caption or first comment | Use tags that describe the post | |
| TikTok | A few, shared with the caption limit | End of caption | Tags help topic search, not guaranteed reach |
| X | One or two | Inside or at the end of the post | Every character counts |
| About three to five | End of post | Use professional topic tags | |
| YouTube | A few | Description or title | The first three appear above the title |
| One to three | In the text | Hashtags matter less here | |
| Two to five | Description | Keywords in title and description matter more | |
| Threads | One | Inside the post | A single topic tag is used as the main tag |
Platforms revise their recommendations often, so treat the numbers as a starting point and check the current guidance from each platform.
CamelCase hashtags and accessibility
Hashtags cannot contain spaces, so words run together. A tag such as #bookclubpicks is easy to misread, and a screen reader will try to pronounce it as one long word. When you capitalize each word, as in #BookClubPicks, the capitals mark the word boundaries. Screen readers can then read the tag word by word, and sighted readers can scan it faster. Hashtags are not case sensitive on major platforms, so you lose nothing in search. This tool turns CamelCase on by default, and you can switch it off for plain lowercase tags.
How to write your own good hashtags
- Describe the post. If a person who followed the tag would not expect your post, remove it.
- Be specific. Add a place, a style, a method or an audience, such as #VeganMealPrepSydney.
- Keep tags short. Short tags are easier to read and type, and long ones are more likely to be mistyped.
- Avoid unrelated trending tags. Using them to get views can be treated as spam.
- Build a brand tag. A short, unique tag of your own helps people find your series or product.
- Check the tag before using it. Search it in the app and look at what appears.
Hashtags for Reels, Shorts and TikTok videos
On short video platforms, hashtags mostly help the system understand the topic, and the video itself decides how far it travels. Keep the set small, put the most descriptive tag first and match it to what is said and shown in the video. A mix of one broad tag, one or two medium tags and one niche tag is a good pattern. Discovery tags such as fyp are optional, and they carry almost no topic information. Captions, on-screen text and spoken words also help platforms classify a video, so use the same keywords in all of them.
Common hashtag mistakes
- Using too many. A wall of tags looks spammy and can distract from the caption.
- Using only huge tags. The post is lost in seconds.
- Copying the same set every time. Change tags to match each post.
- Using misspelled or merged tags. People do not search for them.
- Including banned or unsafe tags. They can limit the reach of the post.
- Treating tags as magic. Good content, clear captions and real engagement matter more.
Cleaning up and organizing a hashtag list
If you keep a notes file of hashtags, it soon fills with duplicates, missing symbols and tags with stray punctuation. The Clean up tab fixes that. Paste the list in any format, and the tool adds a hash symbol to each word, removes spaces, emoji and punctuation, drops tags made of only numbers, removes duplicates regardless of case, sorts and cuts the list to a limit you choose. It also warns about very long tags. Keep several themed lists, for example one per content type, and pick from them for each post rather than pasting the same block every time.
Privacy, limits and responsible use
Your keywords stay in your browser and are not sent anywhere. The suggestions come from your own words and a fixed list, so the tool cannot see live trends, how many posts a tag has or whether a tag is restricted today. Use the results as ideas and check each one in the app. Do not use hashtags that are unrelated to your content, that target or harass people, or that exploit news about a tragedy. Follow the rules of each platform and the law that applies to advertising and sponsored posts in your country, including clear disclosure.
Frequently asked questions
What is a hashtag generator?
A tool that suggests hashtags for a post from a topic or keywords. This one adds variants of your keywords, tags from a built-in list for your niche and a balanced mix of broad, medium and niche tags.
How do I use this free hashtag generator online?
Type a topic, choose your platform, press Generate and click any tag you want to leave out. Then press Copy hashtags and paste them into your caption or first comment.
How many hashtags should I use?
Fewer than you think. Platform guidance favors a few relevant tags, often 3 to 5 on Instagram and 3 to 5 on TikTok and LinkedIn, and one or two on X. The tool sets a sensible default for each platform.
Do hashtags still work in 2026?
They help with topic labeling and discovery, but they are a smaller factor than the content itself, captions and engagement. Use them as labels that describe the post, not as a way to force reach.
What is a good mix of hashtags?
A mix of broad, medium and niche tags. Broad tags have large audiences and heavy competition. Niche tags are more specific, so your post has a better chance of being seen by the right people.
How does the tool decide what is broad or niche?
By how specific the tag is, not by live post counts. A single common word is broad, a short phrase is medium and a long or location-based phrase is niche. This is an estimate, so check the tag in the app.
Does it show how many posts a hashtag has?
No. A browser tool cannot read that data from social networks, and we do not invent numbers. Search the tag in the app to see its size and recent posts.
What is CamelCase and why use it?
Capitalizing each word, as in #MorningRoutine. Hashtags are not case sensitive, but screen readers can read CamelCase tags word by word, and people find them easier to read.
Can I add my own brand hashtag?
Yes. Type it in the brand tag box and it is always included first, so you can build a branded tag over time.
What is the location tag for?
It creates local combinations such as #austincoffee. Local tags have fewer posts, so you are more likely to be seen by nearby people.
What does the Instagram first comment format do?
It puts a few dots on separate lines before the hashtags. Some people paste it as the first comment so the caption stays clean. Hashtags in the caption or the comment both work.
What are discovery tags?
Very broad tags such as fyp or reels. They are optional and off by default, because they have huge competition and little topic value.
Can I clean up a list of hashtags?
Yes. Use the Clean up tab. It adds missing symbols, removes spaces and bad characters, deletes duplicates, sorts the list and cuts it to the limit you choose.
Are some hashtags banned or restricted?
Platforms sometimes restrict tags that are linked to spam or unsafe content, and the list changes. Search a tag in the app before using it, and avoid tags that do not describe your post.
Can I use the same hashtags on every post?
It is better not to. Vary the tags to match each post, because identical sets on every post can look repetitive or spammy.
Is my text stored or sent anywhere?
No. Everything runs in your browser.
Is it free?
Yes. It is free to use online with no sign-up.
