#️⃣ Hashtag Generator
By ToolNimba Editorial Team · Updated 2026-06-19
Enter a keyword or topic, then press Generate.
This hashtag generator turns a keyword or topic into a ready-to-paste set of hashtags. Type one or more words (comma or space separated), and it combines and prefixes them with the # symbol, adds common modifiers, and produces both lowercase and CamelCase variations. You get a copyable block and a live count, so you can stay under the platform limit and post in seconds.
What is the Hashtag Generator?
A hashtag is a word or unspaced phrase preceded by the # symbol that turns text into a clickable, searchable label. When you add #streetphotography to a post, the platform groups it with every other post carrying that exact tag, so people browsing or following that tag can discover your content. Hashtags are how social platforms organise the firehose of public posts into topic feeds, which is why the right tags can put your work in front of people who do not already follow you.
This tool builds tags from the words you supply rather than guessing at trends it cannot see. It strips punctuation, removes spaces (since hashtags cannot contain spaces), and joins multi-word phrases into a single tag. It also breaks longer phrases into their individual words for broader reach, pairs your terms with high-frequency modifiers such as "love", "daily" and "life", and offers a CamelCase version (#StreetPhotography) alongside the all-lowercase form. CamelCase does not change how a tag is matched, since the platform ignores case, but it makes long tags far easier to read and more accessible to screen readers.
More hashtags is not automatically better. Instagram caps a post at 30 hashtags and current guidance from the platform leans toward a smaller, tightly relevant set rather than the maximum. A focused mix of broad tags (large but competitive), medium tags, and specific niche tags usually outperforms thirty generic ones. Treat the output here as a starting shortlist: keep the tags that genuinely describe your post, drop anything off-topic, and refine over time based on which tags actually bring you reach.
When to use it
- Captioning an Instagram, TikTok, or LinkedIn post when you are not sure which hashtags to use.
- Building a reusable block of niche hashtags for a recurring content theme or series.
- Brainstorming tag variations (lowercase and CamelCase) from a single topic keyword.
- Turning a multi-word product or campaign name into a clean, spaceless branded hashtag.
How to use the Hashtag Generator
- Type your keyword or topic. Separate multiple terms with commas or spaces.
- Set the maximum number of hashtags you want (keep it at or below 30 for Instagram).
- Choose a casing style: both, lowercase only, or CamelCase only.
- Press Generate, review the suggestions, then use Copy to paste the block into your post.
Formula & method
Worked examples
You enter the single topic "street photography" with the casing style set to Both.
- The phrase is cleaned and spaces removed: streetphotography
- Lowercase tag: #streetphotography
- CamelCase tag: #StreetPhotography
- Individual words add #street, #Street, #photography, #Photography
- Modifiers add tags like #streetphotographylove and #instastreetphotography
Result: A set led by #streetphotography and #StreetPhotography plus word and modifier variations.
You enter "sunset, travel" with the casing style set to lowercase only.
- Each phrase becomes a tag: #sunset and #travel
- Modifiers add #sunsetlove, #sunsetdaily, #travellife, #travelgram, and more
- The first phrase pairs with the second to make the niche tag #sunsettravel
- Output is trimmed to your chosen maximum, for example the first 30 tags
Result: A lowercase block such as #sunset #travel #sunsetlove #travelgram #sunsettravel ...
Typical hashtag count guidance by platform

Hashtag types and how they balance reach against competition
| Type | Example | Audience size | Competition |
|---|---|---|---|
| Broad | #photography | Very large | Very high |
| Medium | #streetphotography | Moderate | Medium |
| Niche | #londonstreetphotography | Small | Low |
| Branded | #yourbrandname | Owned | None |
Common mistakes to avoid
- Maxing out at 30 generic hashtags. Using the full 30 with broad, off-topic tags rarely helps and can look spammy. A smaller set of tags that genuinely describe your post usually reaches more of the right people.
- Leaving spaces or punctuation in a tag. A hashtag breaks at the first space or symbol, so "#street photography" only tags "street". This tool removes spaces and punctuation for you, joining words into one valid tag.
- Repeating the exact same hashtag block on every post. Pasting an identical set on every post can be flagged as repetitive behaviour and limits discovery. Rotate and tailor your tags to each post instead.
- Assuming CamelCase changes matching. Platforms ignore case, so #TravelLove and #travellove point to the same feed. CamelCase only improves readability and accessibility, it does not create a separate tag.

Frequently asked questions
How does this hashtag generator work?
You enter one or more keywords or a topic. The tool removes spaces and punctuation, joins each phrase into a valid hashtag, breaks multi-word phrases into single-word tags, pairs your terms with common modifiers, and offers lowercase and CamelCase versions. It runs entirely in your browser with no account or network needed.
How many hashtags should I use on Instagram?
Instagram allows up to 30 per post, but current guidance favours a smaller, tightly relevant set, often around 3 to 10 tags. Quality and relevance matter more than quantity, so keep the tags that truly describe your post and drop the rest.
Do hashtags actually increase reach?
Relevant hashtags help platforms surface your post to people searching or browsing that topic, which can extend reach beyond your followers. Off-topic or overly broad tags do little, and a focused mix of broad, medium, and niche tags tends to work best.
Does capitalisation matter in a hashtag?
No. Platforms treat hashtags as case-insensitive, so #TravelLove and #travellove lead to the same feed. CamelCase is purely for human readability and accessibility, especially with longer multi-word tags, and is friendlier to screen readers.
Can I use hashtags with spaces or punctuation?
No. A hashtag ends at the first space or special character, and most punctuation is not allowed inside one. This tool strips spaces and punctuation automatically and joins the words, so "street photography" becomes the single valid tag #streetphotography.
Are the generated hashtags guaranteed to be popular or trending?
No. The tool builds tags from the words you provide and adds common modifiers, but it cannot read live trend or volume data. Use the output as a shortlist, then check each tag on the platform and keep the ones that fit your post and audience.
