YouTube Tags Editor
Paste tags to dedupe them, watch the 500-character limit, click any tag to remove it, and copy the clean list. Everything runs in your browser — nothing is uploaded.
Do tags still matter?
Less than they used to — YouTube says tags play a minimal role compared to titles, descriptions and the video itself. They still help with common misspellings and borderline-duplicate phrasings of your topic. The honest play: spend two minutes here, not twenty, and put the saved time into the title. If you want the whole upload kit — titles, description with chapters, tags and a pinned comment in one run — that's what WhatToUpload does.
