URL Encode & Decode - Explanation & Examples

When working with URLs, certain characters are not allowed or must be represented in a special format. URL encoding converts characters into a safe, standardized format so they can be used in web addresses without causing errors. This tool allows you to quickly encode or decode text for use in URLs, forms, APIs, and web requests.

⭐ What Is URL Encoding?

URL encoding (also known as percent-encoding) replaces unsafe characters with a percent sign followed by a two-digit hexadecimal value. This ensures that URLs follow the rules defined in RFC 3986.

For example:

Character Encoded Description
space%20Spaces are not allowed in URLs
&%26Separates query parameters
/%2FReserved as a path separator
?%3FStarts a query string
=%3DSeparates keys and values

Use encoding whenever a URL contains characters that could be interpreted incorrectly by browsers, APIs, or servers.

⭐ What Is URL Decoding?

URL decoding reverses the process, converting percent-encoded sequences back to normal readable characters. This is useful when you receive encoded URLs from APIs, emails, redirects, logs, or form data.

⭐ Example: URL Encoding

Input:

https://example.com/search?query=hello world & category=books

Encoded Output:

https://example.com/search?query=hello%20world%20%26%20category%3Dbooks

Spaces, ampersands, and equals signs are safely encoded for use in an HTTP request.

⭐ Example: URL Decoding

Input:

name=John%20Doe%20%26%20Sons

Decoded Output:

name=John Doe & Sons

⭐ When Should You Encode a URL?

  • Creating URLs programmatically
  • Sending data in a query string
  • Submitting form values via GET requests
  • Building API request URLs
  • Avoiding errors caused by reserved characters

⭐ When Should You Decode a URL?

  • Reading encoded query parameters
  • Processing incoming data from forms or APIs
  • Debugging redirects or callback URLs
  • Cleaning log or tracking data

⭐ Advanced: Reserved Characters

Some characters have special meaning in URLs and must be encoded unless used for their exact purpose:

  • ? — marks the start of query parameters
  • & — separates key/value pairs
  • = — separates a key from its value
  • # — starts a URL fragment
  • / — separates paths

If they appear as text (not syntax), they must be encoded for the URL to work correctly.

⭐ More Examples

Example: Form value encoding

Input:

email=john+doe@example.com

Encoded Output:

email=john%2Bdoe%40example.com

Example: Complex query string

Input:

/api/items?filter=brand:ACME & sort=price desc

Encoded Output:

/api/items?filter=brand%3AACME%20%26%20sort%3Dprice%20desc
