❓ Frequently Asked Questions
Everything you need to know about URL Validator
What is URL validation?+
Checking if URL follows correct format: protocol://host/path?query#fragment. Validates structure, not whether URL actually exists/works.
Why validate URLs?+
Form input validation, prevent broken links, sanitize user input, debug malformed URLs, ensure correct format before processing.
Difference between valid format and working URL?+
Format valid = proper structure. Working = actually loads. https://invalid-fake-site-xyz.com is valid format but doesn't work. Both checks needed.
What makes URL valid?+
Required: protocol (http/https), host (domain). Optional: path, query string, fragment. Special chars must be URL-encoded.
Is www required for valid URL?+
No! example.com and www.example.com both valid. Most modern sites work without www. Choose one and 301 redirect the other.
Are http and https both valid?+
Yes, both valid URL formats. https = encrypted (recommended). http = unencrypted (deprecated). Modern browsers warn on http sites.
What protocols are valid?+
http, https, ftp, ftps, mailto:, tel:, file:. Most common: http/https. Mobile devices support tel: (auto-dial), mailto: (open email).
Why does my URL show invalid?+
Common issues: missing protocol (just example.com), spaces (use %20), special chars unencoded, double protocol (https://https://).
Can validator catch typos?+
No! Validator checks format only. example.cm (typo for .com) is valid format. Use Status Checker to verify URL actually works.
Are URLs case-sensitive?+
Domain not case-sensitive (example.com = EXAMPLE.com). Path may be case-sensitive depending on server (Linux yes, Windows usually no).
Maximum valid URL length?+
Spec allows unlimited. Browsers practically support 2000-8000 chars. Search engines crawl up to 2000. Keep URLs short and meaningful.
Can URLs have unicode characters?+
Punycode (xn--...) for international domains. Or URL-encode unicode chars in path. Modern browsers handle unicode but encoding safer for cross-platform.
