Frequently Asked Questions

Why do I need to encode HTML?

HTML uses special characters like < and > for tags. If you want to display these characters as text instead of rendering them as code, you must encode them into entities like &lt; and &gt;.

What's the difference between Basic and Full encoding?

Basic only encodes the characters that break HTML syntax (<, >, &, ", '). Full encoding also safely encodes special symbols and non-ASCII characters.

Should I preserve newlines?

Usually yes, if you are encoding a block of code to show in a <pre> tag. If you are encoding to put everything on one line, uncheck it.

What are Hex entities?

Hex entities use hexadecimal numbers (e.g., &#x3C;) instead of decimal numbers (&#60;) or names (&lt;). They all render the same way in a browser.

How do I decode this back?

You can use our HTML Decoder tool to convert encoded entities back to their original characters.
