Hashtag tools for clean, readable tags
Paste your hashtags below. Hashtagr removes duplicates, fixes broken tags, adds capitals so screen readers can say them, and tells you what each platform will accept as of November 2026.
How it works
- 1
Paste
Drop in tags, phrases or a whole caption. Commas, spaces and stray symbols are fine.
- 2
Clean
Duplicates go, spaces become CamelCase, and digits-only or emoji tags are flagged.
- 3
Check
See the count against each platform's cap and copy a list that fits.
Four hashtag tools
Each one does a single job well. None of them needs an account, and none of them sends your text anywhere.
-
Hashtag Formatter & Cleaner
Paste messy tags or phrases and get a clean, deduplicated, CamelCase hashtag list trimmed to a platform's limit.
-
Hashtag Counter
Counts the hashtags and characters in a caption and checks them against X, Instagram, TikTok, LinkedIn, Threads and YouTube limits.
-
Hashtag Set Builder
Build, save and copy reusable hashtag sets in your own browser, with JSON export and import.
-
Hashtag Readability Checker
Scores a hashtag for screen-reader friendliness, ambiguous word breaks and length, and suggests a CamelCase version.

| Threads | 1 topic tag | 1 | 500 |
| YouTube | Over 60 = all ignored | 3 to 5 | 5,000 (description) |
Hashtags on X (Twitter)
X still links every hashtag to a search page, but its help center has long advised using no more than two per post, and X's owner said in December 2024 that the system no longer needs them. One clear tag beats a row of them. Search a tag to see how people actually use it before you join in:

Frequently asked questions
How many hashtags should I use per post?
Fewer than most people think. As of November 2026 Instagram caps posts at five, TikTok shows a five-hashtag limit, Threads takes one topic tag, and X's help center advises no more than two. LinkedIn has no cap, and YouTube ignores every hashtag on a video that has more than 60.
Why should hashtags use CamelCase?
Capitalizing each word (#ThrowbackThursday instead of #throwbackthursday) lets screen readers announce separate words and helps everyone spot the word breaks. It does not change how the tag is matched, because hashtag search ignores letter case on the major platforms.
Does Hashtagr send my hashtags anywhere?
No. All four tools run in your browser with plain JavaScript. Nothing is uploaded, and saved sets are kept in your browser's local storage until you delete them.
Do you publish trending hashtag lists?
No. Hashtagr has no access to platform data and does not scrape it, so it does not publish trending lists or search-volume numbers. Use each platform's own search to see what people are posting right now.
