Frequently Asked Questions

What are HTML entities?
HTML entities are special codes that represent characters that have special meaning in HTML (like <, >, &) or characters not easily typed (like ©, ®, ™). They start with & and end with ;.
What types of entities does this tool support?
Three types: Named entities (&amp;), Decimal entities (&#38;), and Hexadecimal entities (&#x26;). All are equivalent ways to represent the same character.
When should I use HTML entity encoding?
Use it when inserting special characters into HTML content. For example, displaying '<script>' on a webpage requires encoding it as '&lt;script&gt;'.
What characters are always encoded?
The five required entities: & (&amp;), < (&lt;), > (&gt;), " (&quot;), and ' (&#39; in attributes). Other characters like © (©), ® (®), < (>), etc. are optional.
Is my data sent to a server?
No. All encoding and decoding is done locally in the browser using JavaScript string replacement. Your text never leaves your device.
