This free tool counts the hashtags in a post or list. It shows the total, the unique count, repeated tags and the longest tag, and warns you if you pass a limit that you set.

What Is It and When Do You Need It?

Too many or repeated hashtags can look like spam. A quick count helps social media managers stay within the rules of a platform or a client.

Paste your post and optionally type a limit.

How to Use This Tool

  1. Enter or paste your input in the box or boxes above.
  2. Choose the options, if there are any.
  3. Press the button to run the tool.
  4. Read the result and use the copy button where one is shown.

How the Calculation Works

The tool finds all matches of a hash sign followed by word characters, using a pattern that works for all languages. Tags are compared in lower case to find repeats. The report lists the totals, the repeated tags with their counts, the shortest and longest tag, and the total characters used by hashtags.

Worked Example

The post Great day #Travel #travel #beach has 3 hashtags and 2 unique ones, because #Travel and #travel are the same tag.

Common Uses

  • Planning social posts.
  • Cleaning up captions.
  • Checking client briefs.
  • Auditing campaign tags.

Tips and Common Mistakes

  • Put hashtags at the end of a post so it reads well.
  • Keep tags short and clear.
  • Read the current rules of each platform.
  • Check the first result against a case you already know, so you can trust the tool for the rest.
  • Nothing you type leaves your device. The work is done by your browser, so it also works with a slow connection once the page has loaded.

Next, you may need the text statistics counter, list to comma converter, character counter, text repeater.

Everything runs in your browser. Nothing you type is uploaded, stored or sent to any outside service.
