Hashtag Generator

Turn any keyword into relevant, popular and niche hashtag suggestions for Instagram, TikTok, X, LinkedIn and YouTube, with a broad/niche reach mix, favorites and one-click copy. Free and private.

What is the Hashtag Generator?

A Hashtag Generator turns a topic or keyword into a set of relevant hashtags you can add to a post to reach more people. Toollyz Hashtag Generator expands your seed keyword into useful variations and pairs it with curated banks of popular and long-tail tags tuned for each platform — Instagram, TikTok, X, LinkedIn and YouTube — each with its own sensible default count. A reach-mix control lets you lean toward broad, high-volume tags (more reach, more competition) or niche, long-tail tags (smaller audiences that are easier to rank in), and it auto-detects the topic's category (travel, food, fitness, tech and more) to add fitting suggestions. You can shuffle for fresh ideas, save favorites, and copy everything as a ready-to-paste block or one tag per line. Importantly, these are curated, relevance-ranked suggestions generated entirely in your browser — not live trend data scraped from any platform — so nothing you type is ever uploaded.

How to use it

  1. Enter a topic or a few keywords (for example, “vegan recipes”).
  2. Choose your platform and set how many hashtags you want.
  3. Pick a reach mix — broad, balanced or niche — and shuffle for fresh ideas.
  4. Tap any hashtag to copy it, save favorites, or copy the whole set at once.

Frequently asked questions

What is a hashtag generator?

A hashtag generator suggests relevant hashtags for a topic so your posts can reach a wider, more interested audience. You enter a keyword and it returns a mix of popular and niche tags you can copy into your caption.

Are these live trending hashtags?

No — and we're upfront about that. A privacy-first tool that runs entirely in your browser can't pull live trend data from platform APIs. Instead it generates curated, relevance-ranked suggestions from your keyword plus well-known popular and long-tail tags. They're a strong starting point you can refine for your audience.

How many hashtags should I use?

It depends on the platform. Instagram allows up to 30 and many creators use 10–20; TikTok and X do best with just a few highly relevant tags; LinkedIn typically 3–5. The tool sets a sensible default per platform, which you can adjust.

What's the difference between broad and niche hashtags?

Broad hashtags (like #travel) have huge audiences but enormous competition, so your post is seen briefly. Niche hashtags (like #solotraveltips) reach fewer but more relevant people and are easier to rank in. The reach-mix control lets you balance the two.

Which platforms does it support?

Instagram, TikTok, X (Twitter), LinkedIn and YouTube. Each platform gets its own default count and a set of platform-appropriate tags mixed into the suggestions.

Can I save and reuse hashtags?

Yes. Tap the star on any hashtag to save it; your favorites are kept in your browser's local storage and can be copied as a group whenever you need them.

Will it avoid banned hashtags?

It filters against a built-in blocklist of commonly banned or spammy tags, so they won't appear in your suggestions. Platforms change their rules often, so it's still wise to review tags before posting.

Is my topic or keyword stored online?

No. All generation happens entirely in your browser — nothing you type is uploaded. Your last topic, platform and saved favorites are kept only in your device's local storage.

Does it work on mobile?

Yes. The keyword input, platform picker, reach control and hashtag chips are fully responsive and touch-friendly, so you can build hashtag sets on your phone.

Is this hashtag generator free?

Completely free with no signup and no limits. Generating, shuffling, saving favorites and copying are all available to everyone, privately in your browser.
