About the Hashtag Counter

Every platform treats hashtags differently — Instagram caps them at 30, LinkedIn engagement tends to drop past four or five, and a caption padded with duplicates wastes the count without adding reach.

Paste a caption and pick the platform, and see how many hashtags it contains, how many are unique, and whether that total sits inside, at, or past what that platform allows or recommends.

Key features of the Hashtag Counter

Five platforms covered

Instagram, TikTok, X, LinkedIn and Facebook each have their own limits shown.

Duplicate detection

Repeated hashtags are flagged since they waste the count.

Instant results

Counts update live as you type.

Runs in your browser

No sign-up, no data sent anywhere.
