Free Hashtag Generator

Get hashtags grouped by reach for Instagram, TikTok, Facebook and LinkedIn, plus how many to actually post on each. No sign-up required.

How to use this hashtag generator

Most free hashtag generator tools hand you a block of thirty tags and leave you to paste them. This one groups them by size and tells you how many to use, because those are the two things that decide whether hashtags do anything at all.

1. Describe your post

Type what the post is about and pick the platform. Being specific matters more than being broad, because the useful hashtags are the specific ones.

2. Get them grouped by reach

Hashtags come back in three tiers: broad, medium and niche. Mixing sizes is what keeps a post visible, and it is the part most generators skip entirely.

3. Use the recommended few

The tool tells you how many to actually post for your platform, and gives you that set ready to copy. The full pool is there to choose from, not to paste wholesale.

How many hashtags should you actually use?

Fewer than you have probably been told. The advice to fill all 30 Instagram slots comes from a period when hashtag browsing was a real discovery channel. It is not any more: Instagram removed hashtag following, shifted to recommendation-led feeds, and has said plainly that hashtags do not meaningfully increase reach.

Instagram. Around 3 to 5 relevant tags. The 30 cap still exists, but using it is not the advice any more.
TikTok. 3 to 5, specific and descriptive. Broad tags are so saturated they carry almost no signal, which is what a hashtag generator tiktok users can trust has to account for.
Facebook. 1 to 3. Hashtags do least here of any major platform, so a hashtag generator for facebook posts should return restraint rather than volume.
LinkedIn. 3 to 5. These behave as followable topics, so a few professional ones put you in front of people tracking that subject.

This is why the tool leads with a short recommended set and puts the full pool underneath. The pool is for choosing from.

Why hashtags are grouped by reach

A hashtag with 40 million posts and one with 4,000 do completely different jobs, and using only the first kind is the most common mistake. On a huge tag your post is buried within seconds by accounts far larger than yours. On a small, specific tag it can stay near the top for hours, in front of people who chose to look at that subject.

So the generator returns three tiers. Broad tags are worth one or two picks for the chance of a spike. Medium tags are where most of your choices should come from. Niche tags reach fewer people but a much higher proportion of the right ones. That mix outperforms any single tier used alone, and it is the part a flat list of thirty tags cannot give you.

Frequently asked questions

What is the 5 hashtag rule?

It refers to Instagram's current guidance that around 5 relevant hashtags works better than piling on 30. Instagram has said directly that hashtags do not meaningfully boost reach any more, and that relevance matters more than quantity. The old advice to fill all 30 slots dates from an era when the algorithm worked differently.

What is the 5-3-1 rule on Instagram?

A commonly shared formula suggesting 5 hashtags about your niche, 3 about your specific content and 1 branded to you. It is a community rule of thumb rather than anything Instagram publishes, but the thinking behind it is sound: mix levels of specificity instead of using nine variations of the same broad term. The tiers above follow the same logic.

Why does Instagram limit you to 5 hashtags?

It does not, technically. The hard cap is still 30 per post. What changed is the advice: Instagram now recommends around 3 to 5 because relevance beats volume, and stuffing hashtags can look like spam. So 5 is guidance, not a limit, and the tool shows you both numbers.

Do hashtags increase reach on Instagram?

Much less than they used to, and Instagram has said so publicly. They now work mainly as topic labels that help the system understand what a post is about, rather than as a discovery channel people browse. Good hashtags still help the right audience find you, but they will not rescue a post that nothing else is working for.

Is it still worth using hashtags on Instagram?

Yes, but with realistic expectations. A few relevant hashtags cost nothing and give the algorithm useful context about your subject. What is no longer worth doing is spending real time researching 30 of them, or copying blocks of unrelated popular tags, which at this point is more likely to hurt than help.

Why don't hashtags work on Instagram anymore?

Instagram shifted from hashtag-led discovery to recommendation-led discovery. The feed now surfaces content based on what it understands about the post and what it knows about each viewer's interests, so the hashtag is one signal among many rather than the main route in. Hashtag following was also removed, which took away a lot of the browsing behaviour they depended on.

What is replacing hashtags on Instagram?

Searchable captions and on-screen text. Instagram now reads the words in your caption, the text in your image or video, and your audio, and uses all of it to decide who should see the post. In practice that means writing a caption that says plainly what the post is about does more than a hashtag block ever did.

Can ChatGPT generate hashtags?

It can, and this tool uses a language model to do exactly that. The difference is in what comes with them. A raw chat response gives you an undifferentiated list, while this groups them by reach, tells you how many to actually use on your platform, and cleans them so none contain spaces or punctuation that would silently break the tag.

What's a good hashtag for Instagram?

One that describes your post specifically enough that someone browsing it would want to see your content. A tag with 40 million posts buries you in seconds. One with a few thousand, closely matched to what you actually posted, puts you in front of people who care. That is why the generator returns niche tags rather than only the obvious big ones.

How do I create my hashtag on Instagram?

You simply use it. There is no registration step: type a hash symbol followed by an unbroken run of letters or numbers and the tag exists. Before adopting a branded one, search it first to check nobody else has claimed it and that it has no unfortunate second reading. Keep it short and easy to spell.

Is #fyp a good hashtag?

Not really. It is one of the most used hashtags on TikTok, which means it carries almost no information about your video and places you against a firehose of unrelated content. TikTok's system already decides what reaches the For You page based on watch time and engagement, and a hashtag does not lobby it. Specific descriptive tags do more.
