Frequently Asked Questions
What does the Hashtag Cleaner do?
It parses hashtags from pasted text, removes duplicates and invalid entries, normalizes casing, optionally sorts alphabetically, and outputs a clean list ready to paste into TikTok, Instagram, or YouTube.
What counts as an invalid hashtag?
Tags with no letters or numbers after the # symbol, tags longer than 100 characters, or tags containing only punctuation are removed when "Remove invalid tags" is enabled.
Are duplicate hashtags case-sensitive?
By default, no — #Creator and #creator are treated as the same tag when duplicate removal is on.
Is my text stored or sent anywhere?
No. All cleaning runs entirely in your browser.
Is this tool free and does it work on mobile?
Yes on both counts. The Hashtag Cleaner on draft21 is completely free with no sign-up required and works on all devices.
