Common Use Cases

🔍

Debug Parameters

Decode complex query strings like UTM tags `?utm_source=google...` into a clean list.

👮

Security Audit

Quickly identify if a URL is using insecure `http://` or uses standard ports.

🏗️

Structure Analysis

Break down a URL into its components: protocol, hostname, port, path, query, and hash.

✅

Syntax Check

Verify proper formatting before saving URLs to a database or using them in redirects.

Why use a URL Validator?

Debugging complex URLs with many parameters can be tedious. This tool does the heavy lifting for you by validating against official standards.

Syntax Check: Ensure the URL follows the standard format defined in RFC 3986.
Parameter Decoder: Automatically splits messy query strings into a structured table.
Component Inspection: Isolate specific parts like the domain or path for verification.

URL Parsing in Code

Parsing URLs is a fundamental task in web development. Here is how to do it natively in different languages.

JavaScriptURL API

try {
  const myUrl = new URL('https://example.com/path?name=Vue');

  console.log(myUrl.hostname); // "example.com"
  console.log(myUrl.protocol); // "https:"
  console.log(myUrl.searchParams.get('name')); // "Vue"
} catch (e) {
  console.error("Invalid URL format");
}

Pythonurllib.parse

from urllib.parse import urlparse, parse_qs

url = "https://example.com/path?id=123"
parsed = urlparse(url)

print(parsed.netloc) # "example.com"
print(parsed.scheme) # "https"
print(parse_qs(parsed.query)) # {'id': ['123']}

PHPparse_url

$url = "https://example.com/path?arg=1";
$parts = parse_url($url);

echo $parts['host'];   // "example.com"
echo $parts['path'];   // "/path"
echo $parts['query'];  // "arg=1"

Javajava.net.URL

import java.net.URL;

URL url = new URL("https://example.com/api");
System.out.println(url.getProtocol()); // "https"
System.out.println(url.getHost());     // "example.com"

Frequently Asked Questions

What is a URL scheme?

The scheme (or protocol) tells the browser how to access the resource. Common schemes are http, https, ftp, and mailto.

Are URL parameters case-sensitive?

Generally, yes. While the domain name is case-insensitive, the path and query parameters (after the ?) are case-sensitive on Linux/Unix servers.

Which characters are allowed in a URL?

Alphanumeric characters `-`, `_`, `.` and `~`. All other special characters (like space, `@`, `#`) must be percent-encoded.

Does this tool support IDN domains?

Yes, modern browsers handle Internationalized Domain Names (IDN) by converting them to Punycode (e.g., `xn--...`).

What is proper URL encoding?

Use `%20` for spaces in paths and `+` or `%20` in query strings. Use our URL Encoder tool to handle this automatically.
