What Is a URL Encode Decode Tool?

A URL encode decode tool is an online utility that converts normal text into URL-safe encoded format and converts encoded URLs back into readable text. URL encoding is also known as percent encoding because special characters are converted into percent-based values such as %20, %26, and %3D.

This tool is useful when a URL contains spaces, symbols, query parameters, Unicode characters, or reserved characters that must be safely transmitted in a web address.

This tool is useful for:

  • Encoding URLs online
  • Decoding URL encoded strings
  • Encoding query parameters
  • Decoding query strings
  • Converting spaces to %20 or plus signs
  • Debugging API URLs
  • Cleaning tracking and campaign URLs

How to Encode or Decode a URL Online

Using the URL Encode Decode tool is simple:

  • Paste your URL, query string, or text into the input box
  • Choose URL Encode or URL Decode
  • Select the conversion mode if available
  • Click the convert button
  • Copy or download the converted result

The entire process happens instantly inside your browser.

Percent Encoding Tool

URL encoding uses percent encoding to replace unsafe or reserved characters with a percent sign followed by hexadecimal values.

Examples:

Percent Encoding Examples
Space = %20
&     = %26
=     = %3D
?     = %3F
/     = %2F
%     = %25

UTF-8 and Special Character Support

Encode and decode special characters, symbols, Unicode text, and international characters for safe use in URLs.

Useful for:

  • Multilingual URLs
  • Special symbols
  • International search queries
  • Encoded API values

Common URL Encoding Examples

Character Encoded Value Meaning
Space %20 Space character
& %26 Ampersand
= %3D Equals sign
? %3F Question mark
/ %2F Forward slash
# %23 Hash symbol
% %25 Percent sign
@ %40 At symbol

URL Encoding vs URL Decoding

URL encoding converts unsafe or reserved characters into URL-safe percent-encoded values. URL decoding converts those encoded values back into readable text.

For example, a space may become %20 when encoded. When decoded, %20 becomes a normal space again.

URL Encoding vs HTML Encoding

URL encoding and HTML encoding are different. URL encoding is used for web addresses, query strings, and URL parameters. HTML encoding is used to display special characters safely inside HTML content.

Use URL encoding when working with links, API endpoints, redirect URLs, and query parameters. Use HTML encoding when you want to display HTML characters such as <, >, and & safely on a web page.
