Hashtag Cleaner — free online tool

You copied a bunch of hashtags from somewhere, and now they're a mess. Some have a #, some don't. A few are repeated. The case is all over the place. Cleaning that up by hand before a post is annoying. We added a free tool that does it for you — Hashtag Cleaner — right in your browser.

What it does

Paste any messy mix of hashtags — with or without the #, with duplicates, in mixed upper and lower case — and it hands you back a clean, tidied-up set. It removes the repeats, sorts out the formatting, and gives you one neat block that's ready to copy.

Nothing leaves your device

The whole thing runs in your browser. Your hashtags are never uploaded anywhere and nothing is saved. When you close the tab, it's gone. Nobody else sees what you paste in.

How to use it

  1. Open Hashtag Cleaner and paste your messy hashtags into the box.
  2. The tool cleans them up right away — duplicates gone, formatting fixed.
  3. Copy the clean set and drop it straight into your post.

It's free with no limit. There are more small tools on the Apps page.
