Hashtag Cleaner
Add or remove #, remove duplicate hashtags (optionally ignoring case and full-width forms), sort them and count them. Works with hashtags in any language and with emoji; spaces and symbols are handled for you.
- Runs in your browser (no upload)
Tags are separated by spaces, commas, line breaks and #. You can paste a whole post.
Each line or comma-separated item becomes one tag; spaces inside are handled like other characters that cannot be used.
Tags keep letters and digits of any language, underscores (_) and emoji.

Changes and notes
- Tags whose unusable characters were handled:
new-york→ #newyorkTravel!→ #Travel
- Some networks do not treat tags made only of digits as hashtags: #2024
Which characters work in hashtags
- The help centers of X, Instagram and Facebook say that hashtags with spaces, punctuation or special characters (such as $ or %) do not work properly. This tool removes those characters, replaces them with _ or splits the tag there.
- Letters and digits of every language, underscores (_) and emoji are kept. Some networks do not support emoji in hashtags; choose “Remove emoji” if needed.
- Tags that differ only in upper/lower case or full-width/half-width characters are usually treated as the same tag, so they are merged as duplicates (you can change this).
- Limits on the number of tags and the exact character rules differ between networks and can change (for example, Instagram’s help allows up to 5 tags per post and X’s help recommends no more than 2). Check each service’s help before posting.
How to use
- Paste your hashtags or a whole post.
- Choose how to read the input, how to handle symbols and duplicates, the order, and whether to output # and which separator.
- Check the cleaned list and the counts, then copy it.
FAQ
Can I use hashtags in other languages or with emoji?
Yes. Letters and digits of every language, underscores and emoji are kept. Some networks do not support emoji in hashtags; choose “Remove emoji” in that case.
What happens to a tag like #new-york?
Most networks cut a hashtag at a symbol, so you can remove the symbol (#newyork), replace it with _ (#new_york) or split the tag there (#new #york).
