The 30-tag limit is a hard wall
Instagram allows at most 30 hashtags per post. Pasting your usual mega-list without checking means either an error at publish time or silently dropped tags. This tool counts the unique tags — because duplicates never counted anyway.
Duplicates and banned tags are wasted slots
Every duplicate and every banned tag occupies a slot that a working tag could have used. The cleaner strips both automatically and shows you exactly what it removed and why, so your final 30 all pull their weight.
Copy a set that just works
The cleaned set is one click to copy and safe to paste straight into your caption or first comment. Build the list once, clean it here, reuse it forever.
