Why Do We Encode URLs?

Uniform Resource Locators (URLs) can only be sent over the internet using the ASCII character set. If a URL contains characters outside the ASCII set (like spaces, emojis, or special symbols like ? and & used in data), the URL has to be converted. URL encoding replaces unsafe ASCII characters with a % followed by two hexadecimal digits.

Examples of Encoding

• Space ( ) becomes %20
• Ampersand (&) becomes %26
• Question Mark (?) becomes %3F

How Our Tool Works

This tool uses standard JavaScript functions encodeURIComponent() and decodeURIComponent() to process your text directly in your web browser. No data is sent to our servers, making it completely safe for parsing private API keys, user tokens, or proprietary query parameters.
