Understanding URL Encoding and Decoding

URL encoding, also known as percent encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). It is used to represent characters that have special meaning in URLs or cannot be represented directly in ASCII.

Our free URL encoder/decoder tool helps developers properly encode and decode URL strings, ensuring that special characters are handled correctly in web applications, APIs, and URLs.

Why URL Encoding is Important

Special Characters: URLs can only contain ASCII characters. Special characters like spaces, ampersands, and non-ASCII characters must be encoded.
API Development: Proper URL encoding is essential when working with REST APIs and query parameters.
Security: Encoding prevents injection attacks and ensures data integrity in URLs.
Compatibility: Ensures URLs work correctly across all browsers and servers.

Common URL Encoding Use Cases

Query parameter encoding in API requests
Form data submission
File path encoding
Email link generation
Social media sharing URLs

All URL encoding and decoding happens locally in your browser, ensuring complete privacy and security for your data.

Code Examples

URL Encoding Example

Original: Hello World!
Encoded: Hello%20World%21

Original: user@example.com
Encoded: user%40example.com

Original: price=$100&discount=20%
Encoded: price%3D%24100%26discount%3D20%25

Query Parameter Encoding

Original URL:
https://api.example.com/search?q=hello world&category=all

Encoded URL:
https://api.example.com/search?q=hello%20world&category=all

JavaScript URL Encoding

// Encode
const encoded = encodeURIComponent('Hello World!');
// Result: Hello%20World%21

// Decode
const decoded = decodeURIComponent('Hello%20World%21');
// Result: Hello World!
