Free hashtag formatter—parse messy tag lists, strip duplicate # marks, dedupe case-insensitively, and copy clean space- or comma-separated hashtags for Instagram, TikTok, and LinkedIn captions in your browser.
It turns messy pasted tag soup into a clean, deduplicated list. Split on spaces, commas, or line breaks; remove leading # characters; ignore empty tokens; and keep the first spelling when two tags differ only by case. Output includes space-separated and comma-separated strings ready to paste into captions or spreadsheets.
Comparison is case-insensitive—#Marketing and #marketing collapse to the first version you typed. Punctuation attached to a token stays unless you remove it manually before formatting. The formatter does not reorder tags for relevance; it preserves discovery order from your paste.
Instagram allows more tags in theory, but many marketers see better reach with roughly thirty or fewer focused tags. The soft warning is guidance, not a hard block—you can still copy longer lists and test in your account analytics.
TikTok discovery often highlights a small set of core tags—commonly cited around three to five—that match your niche plus one broad tag. The formatter shows a soft warning when you are far below or above that band so you can rebalance before posting.
Yes. Words separated by spaces, commas, or new lines are accepted with or without a leading hash. The output always adds a single # per tag in the copy fields so you do not double-hash accidentally.
No. Parsing runs locally in the browser. Influencer campaign tag sets and unreleased launch hashtags stay on your device.
Use this tool to clean and dedupe tag lists. Use Social Character Counter when you need to know how many graphemes your full caption—including hashtags—consumes on each network. Many workflows format tags here first, then paste the caption into the counter.
