Hashtag Cleaner
Paste words or phrases and get clean, deduplicated hashtags — lowercase or camelCase — ready to drop into any social post.
From phrases to clean hashtags
Building a hashtag set by hand means fiddling with spaces, capitalization, and duplicates in the caption box. This tool does it in one step: paste your topics — one per line or comma-separated — and it returns properly formatted hashtags with spaces and punctuation stripped, invalid characters removed, and repeats deduplicated.
Choose lowercase for the classic look, or camelCase — like #SocialMediaMarketing — which is easier for screen readers to announce word by word and often looks cleaner for multi-word tags. Copy the finished set straight into Instagram, LinkedIn, X, TikTok, or wherever you post.

It all runs in your browser — no accounts, no uploads, no waiting.
Frequently Asked Questions
What does the hashtag cleaner do?
It turns a list of words or phrases into clean, valid hashtags — removing spaces and punctuation, deduplicating, and formatting each as a single #tag ready to paste into a post.
How are multi-word phrases handled?
Each line or comma-separated phrase becomes one hashtag. You can choose lowercase (#socialmedia) or camelCase (#SocialMedia), which is friendlier for screen readers.
Does it remove duplicate tags?
Yes. Repeated tags are removed automatically so you do not accidentally post the same hashtag twice.
Is my text private?
Yes. Everything runs in your browser — nothing is uploaded or stored.
