Tag Deduplicator
Remove duplicate tags while preserving the original order.
Normalise a messy tag list into clean, unique entries.
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 List Cleaner is the general-purpose repair tool: it splits on any separator, trims whitespace, drops empty entries, optionally removes hash symbols and lowercases everything, then removes duplicates. Every option is a switch, so you can keep original casing when it matters.
