HTML Encoder/Decoder

HTML Encoder Documentation

HTML encoding is the process of converting special characters into their HTML entity equivalents. This ensures that text is displayed correctly in web browsers and prevents potential security vulnerabilities.

What is HTML Encoding?

HTML encoding converts special characters into HTML entities. For example:

• < becomes <
• > becomes >
• & becomes &
• " becomes "
• ' becomes '
