What is URL Encoding?

URL encoding (also called percent encoding) is a mechanism to encode information in a Uniform Resource Identifier (URI) under certain circumstances. It converts characters into a format that can be transmitted over the Internet.

URLs can only be sent over the Internet using the ASCII character-set. Since URLs often contain characters outside the ASCII set, they must be converted into a valid ASCII format.

When to Use URL Encoding

Required Encoding

  • • Query parameters with spaces
  • • Special characters in URLs
  • • Non-ASCII characters
  • • Reserved URL characters

Common Examples

  • • Search queries with spaces
  • • Form data submission
  • • API parameter passing
  • • Email addresses in URLs

URL Components

A complete URL consists of several components:

https://example.com:8080/path/to/page?param1=value1&param2=value2#section
  • Protocol: https://
  • Hostname: example.com
  • Port: :8080
  • Path: /path/to/page
  • Query: ?param1=value1&param2=value2
  • Fragment: #section

Frequently Asked Questions

What does URL encoding actually do?

URL encoding (percent encoding) converts characters that are unsafe or reserved in a URL into a %XX format so the address can be transmitted reliably. For example, a space becomes %20.

Is my URL or text sent to any server?

No. Encoding, decoding, and analysis all run in your browser. Whatever you paste stays on your device, so you can safely process URLs that contain private tokens or parameters.

When do I need to encode a URL?

Encode whenever a value contains spaces, non-ASCII characters, or reserved symbols, such as search queries, form data, email addresses, or API parameters passed in a query string.

Can the tool break a URL into its parts?

Yes. It can analyze a URL and show its components, such as protocol, hostname, port, path, query, and fragment, and parse individual query parameters for easier inspection.

What is the difference between encoding and decoding here?

Encoding converts readable text into the percent-encoded form safe for URLs, while decoding reverses it back to readable text. You can swap input and output to move in either direction.
