URL Encoding

What is HTML Encoding?

HTML encoding converts special characters into HTML entities to display them safely in web pages. This prevents browsers from interpreting them as HTML code.

Common HTML Entities

&&Ampersand
<&lt;Less than
>&gt;Greater than
"&quot;Double quote
'&#39;Single quote

Use Cases

  • XSS Prevention: Safely display user input
  • Code Display: Show HTML/XML code in web pages
  • Data Transmission: Safely send data in URLs or forms
  • Email Content: Display special characters correctly
  • Database Storage: Store text with special characters

URL Encoding

URL encoding (percent-encoding) converts characters into a format that can be transmitted over the Internet. Special characters are replaced with % followed by hexadecimal digits.

Security Note

Always encode user input before displaying it on web pages to prevent Cross-Site Scripting (XSS) attacks. This tool helps you safely handle special characters in your applications.
