About HTML Encoding
HTML encoding is the process of converting special characters to their corresponding HTML entities. This is important for several reasons:
- Displaying special characters: Some characters have special meaning in HTML (like < and >) and need to be encoded to display properly.
- Preventing XSS attacks: Encoding user input helps prevent cross-site scripting (XSS) attacks by ensuring that browser doesn't interpret the input as executable code.
- Character set compatibility: HTML entities ensure that characters display correctly regardless of the document's character encoding.
Types of HTML Entities
HTML entities can be represented in two ways:
- Named entities: Use a name to represent the character, like < for <
- Numeric entities: Use the character's Unicode code point, like < for <
This tool supports both encoding and decoding of HTML entities, making it easy to convert between regular text and HTML-safe text.
