Complete Guide

What is URL Encoding?

URL encoding (also called percent encoding or application/x-www-form-urlencoded) is a mechanism for converting characters into a format that can be safely transmitted over the internet. It replaces special characters with a percent sign (%) followed by two hexadecimal digits representing the character's ASCII value.

Why Do We Need URL Encoding?

  • Reserved Characters: Some characters have special meanings in URLs (?, &, =, #) and must be encoded
  • Unsafe Characters: Spaces and other characters aren't safe for URL transmission
  • International Characters: Non-ASCII characters must be encoded for compatibility
  • Data Integrity: Ensures data isn't misinterpreted by servers or browsers
  • Query Parameters: Required for passing data through URL query strings

Common Reserved Characters

  • ? - Marks the start of query string
  • & - Separates query parameters
  • = - Separates parameter name from value
  • # - Indicates fragment identifier
  • / - Path separator
  • : - Port separator
  • @ - Username/password separator

URL Encoding Rules

  • Unreserved Characters: A-Z, a-z, 0-9, -, _, ., ~ (not encoded)
  • Reserved Characters: Must be encoded if used outside their special context
  • Other Characters: All other characters must be encoded as %XX
  • Encoding Format: % followed by two hexadecimal digits

Real-World Example

Original URL: https://example.com/search?q=hello world&sort=date

Encoded URL: https://example.com/search?q=hello%20world&sort=date

Pro Tip: Most modern web frameworks automatically handle URL encoding, but it's crucial to understand it for APIs, form submissions, and debugging issues with special characters in URLs.

FAQ

Encoding converts normal text to URL-safe format (spaces become %20). Decoding does the reverse (converts %20 back to spaces). This tool handles both.
Modern browsers automatically encode URLs, but it's crucial when building URLs programmatically, working with APIs, or using special characters.
International characters (Unicode) are first converted to UTF-8 bytes, then each byte is percent-encoded. Our tool handles this automatically.
Space has ASCII code 32 in decimal, which is 20 in hexadecimal. Hence %20. This is the standard URL encoding for spaces.
Yes! URL encoding is reversible. Any encoded URL can be decoded back to its original form without data loss.
Typically, you only encode the query parameters and path components, not the protocol (http://) or domain name.
& is reserved for separating query parameters, so it gets encoded as %26. However, use it carefully as a parameter separator.
