Channel URL Validator
Check a YouTube channel handle or @username — verify it follows YouTube's naming rules and get a clean channel URL.
Introduction
Handles are how the world finds YouTube channels now. They appear in bios, link-in-bio pages, collab documents, and support tickets — and they get copied wrong more often than you'd think. A handle can't be shorter than 3 or longer than 30 characters, must start and end with a letter or number, and can't contain consecutive dots or underscores. The Thumbix Channel URL Validator checks all of that instantly. Paste any handle, @username, or channel URL and the tool normalizes it, tells you whether it's valid, lists the specific rule it breaks if it isn't, and hands you a clean youtube.com/@handle URL to copy.

What Is This Tool?
A Channel URL Validator checks a YouTube handle against the platform's naming rules and produces a canonical channel URL. It accepts a bare handle, an @username, or a full channel URL, normalizes the input, and validates it character by character.
The output is practical: a clean youtube.com/@handle URL when the handle is valid, or a specific, actionable list of rules when it isn't.
How Does It Work?
Validation follows the exact rules YouTube applies to handles:
- It normalizes the input — removing @, protocol, and path noise.
- It checks length — handles must be between 3 and 30 characters.
- It checks the character pattern — start and end with a letter or number, no consecutive dots or underscores.
- It returns a clean channel URL for valid handles, or a list of violations.
No server calls, no login — the entire check is local and instant.
