Tag List Cleaner
Normalise a messy tag list into clean, unique entries.
Remove duplicate tags while preserving the original order.
Paste tags separated by commas, line breaks, semicolons or pipes — mixed separators are fine.
Results update as you type. Nothing leaves your browser.
The Tag Deduplicator does one job precisely: it removes repeats using a case-insensitive comparison while keeping the first occurrence and the original order. Nothing else about your list is changed.
