What is URL Encoding and Decoding?

URL encoding (also called percent encoding) is a mechanism for converting special characters in URLs into a format that can be transmitted over the internet. URL decoding reverses this process, converting encoded characters back to their original form. This tool handles both operations instantly and accurately.

Why Do We Need URL Encoding?

🌐 Special Characters

URLs can only contain certain ASCII characters. Special characters must be encoded.

🔗 Query Parameters

Safely pass data in URL query strings without breaking the URL structure.

🌍 International Text

Support non-ASCII characters like Chinese, Arabic, or emoji in URLs.

🛡️ Data Integrity

Prevent conflicts with URL reserved characters and maintain data accuracy.

Common URL Encoding Examples

Space: space becomes %20 or +

Question Mark: ? becomes %3F

Ampersand: & becomes %26

Equal Sign: = becomes %3D

Forward Slash: / becomes %2F

At Symbol: @ becomes %40

Understanding Percent Encoding

Percent encoding uses the percent sign (%) followed by two hexadecimal digits representing the ASCII code of the character. For example, the space character (ASCII 32) is represented as %20. This ensures that all characters in a URL are from the allowed ASCII set.

Reserved vs Unreserved Characters

Reserved characters have special meaning in URLs and must be encoded when used literally: : / ? # [ ] @ ! $ & ' ( ) * + , ; =

Unreserved characters don't need encoding: A-Z a-z 0-9 - _ . ~
