How it works
How HTML Encoding and Decoding Works
HTML uses special characters called entities to represent reserved symbols and non-standard characters.
For example:
| Character | HTML Entity |
|---|---|
< |
< |
> |
> |
& |
& |
" |
" |
' |
' |
Encoding HTML
When encoding HTML, special characters are replaced with their corresponding entities.
Example:
<div>Hello & Welcome</div>
becomes:
<div>Hello & Welcome</div>
Encoding helps prevent HTML from being interpreted by browsers and is commonly used for displaying code snippets and sanitizing user-generated content.
Decoding HTML
Decoding performs the reverse operation.
Example:
<div>Hello & Welcome</div>
becomes:
<div>Hello & Welcome</div>
This is useful when content has been escaped during storage, transmission, or processing.
