Hashtag and YouTube Tag Tools
Free tools that run in your browser. Nothing you type is sent anywhere.
Hashtag generator
Turn a topic into a focused starter set, sized for the platform you post to (5 for Instagram).
Hashtag counter and formatter
Paste any list to remove duplicates, fix formatting and check it against platform limits.
YouTube tag generator
Build comma-separated YouTube tags that fit the 500-character limit, plus matching hashtags.
How these tools work
The tools use simple, transparent rules. They do not know live popularity or trends, so treat the output as a starting point and check each tag on the platform. Platform limits change; we note the date we last checked each rule on the platform guides.
