What is this hashtag formatter?
A free, browser-based tool that cleans up a list of hashtags: it removes duplicates (case-insensitively), prefixes every tag with '#', counts them, and flags the count against per-platform recommendations for Instagram and X. Paste a messy set, copy a tidy one. Everything runs in your browser, so your text is never uploaded.
How to use it
- Paste your hashtags or words on the left.
- Check the unique count and the per-platform recommendations.
- Copy the cleaned, deduped set into your post.
Common use cases
- Reusing a saved hashtag set without accidental duplicates.
- Keeping Instagram tags near the recommended count.
- Tidying tags copied from several sources.
