URL Encoder

💡 About This Tool

Encode or decode URL components to ensure safe transmission over HTTP. Essential for handling query parameters containing special characters, spaces, or non-ASCII text (UTF-8).

📘 Usage Tips

• Percent-Encoding Converts unsafe characters into %xx hex format (e.g., space becomes %20). Ensures compliance with RFC 3986.
• Debug Query Strings Decode complex, nested query parameters from logs or analytics URLs to inspect the raw data structure.
• Fix Broken Links Quickly sanitize URLs containing reserved characters that might otherwise break routing or API calls.

🧐 Frequently Asked Questions

Q. What is "%20"?

A. The percent-encoded representation of a space character. URLs cannot contain literal spaces; they must be encoded as %20 or + (application/x-www-form-urlencoded).

Q. Why encode?

A. URLs are limited to a subset of ASCII characters. Reserved characters (like &, =, ?) have special meanings, and non-ASCII characters must be encoded to be interpreted correctly by web servers.

📚 Trivia

Browsers often display decoded URLs in the address bar for user friendliness (IRI), but the underlying request always uses the percent-encoded ASCII string.
