Hashtag Generator: Format a Keyword List into Clean Hashtags

Paste or type your keywords, one per line or comma-separated. They come back as hashtags in the case you choose, with the count, the character total and a check against each platform’s rules. It formats the list you give it; it does not invent tags.

What this hashtag generator does, and what it does not

Most pages called "hashtag generator" ask for a topic and return a list of tags they claim are trending. This one does the other half of the job: you already know the words, and it turns them into hashtags that will actually work. Multi-word phrases lose their spaces and get joined in camelCase (#filmPhotography), PascalCase (#FilmPhotography), lowercase or UPPERCASE; a # is added if missing; blank entries and stray punctuation are dropped. Camel or Pascal case is worth using on anything longer than one word, because screen readers announce #FilmPhotography as two words and #filmphotography as one unpronounceable one, and sighted readers parse it faster too. Platforms treat all four the same: hashtags are case-insensitive everywhere.

The output can be styled with any of the site’s Unicode fonts, but read the warning under the box before you do: a styled hashtag is not a hashtag. Instagram, TikTok and X stop reading a tag at the first character that is not a letter, digit or underscore, and a mathematical bold A is neither, so #𝐟𝐢𝐥𝐦 is just decoration and links to nothing. Use the styles for a caption, never for the tags you want indexed.

Hashtag generator for Instagram, TikTok, YouTube and X: the limits

Every platform has a rule, and the checks under the output apply all of them to your list at once. Instagram allows up to 30 hashtags per post or comment; a 31st makes the whole comment fail silently. TikTok has no cap on the number, only the 2,200-character caption, which hashtags count toward. X has no cap either but every tag counts against 280 characters. YouTube reads hashtags from the description, shows the first three above the title, and ignores all of them if there are more than 60. LinkedIn has no limit; three to five is the usual advice. Threads takes a single topic tag per post, and adds no # sign. The separator control lets you put the tags on one line, on separate lines, or with a dot or sparkle between them, which is how they are usually hidden at the bottom of an Instagram caption.

The check also flags things a platform will reject or silently break: a tag that is numbers only (#2024 is not clickable on Instagram or X), a duplicate (counted once, and some apps refuse the post), and a symbol inside a tag, which ends it early. Hashtags may contain letters from any alphabet, digits and underscores, but not hyphens, spaces or emoji.

How many hashtags should you use?

Fewer than you think, and specific ones. Instagram’s own guidance since 2021 has been three to five relevant tags rather than the maximum thirty, and its search now matches caption words as well as hashtags, so the tag no longer has to carry the whole topic. TikTok recommends a mix of one or two broad tags and several specific ones. On X, more than two looks like spam. The presets above are starting lists for common topics; replace them with the words that actually describe the post, and the generator does the formatting.

Hashtag generator questions

Does this hashtag generator suggest trending hashtags?

No. It formats the keywords you give it into valid hashtags and checks them against platform limits. Trending suggestions come from a platform’s own search (type a tag on Instagram or TikTok and the app shows post counts), which is more current than any third-party list.

How many hashtags can I use on Instagram?

Thirty per post or comment. Post a 31st and the comment fails without a message. The check under the output turns red at 31. Instagram itself recommends three to five specific tags rather than the maximum.

Should hashtags be camelCase?

For multi-word tags, yes: #FilmPhotography is read correctly by screen readers and by people, #filmphotography is not, and platforms treat both as the same tag because hashtags are case-insensitive. Pick Pascal or camel case in the tool and the words are capitalised for you.

Can hashtags have fancy fonts or symbols?

They can, but they stop being hashtags. A hashtag ends at the first character that is not a letter, digit or underscore, and styled Unicode letters count as symbols, so #𝐟𝐢𝐥𝐦 links to nothing. Style the caption if you like; keep the tags plain.

Do hashtags count toward the character limit?

Yes, on every platform. The character total shown under the output is what the tags add to a caption; the X check uses the 280-character post limit, the TikTok and Instagram checks the 2,200-character caption.
