Frequently asked questions

How do I encode <, > and & for HTML?

Paste your text in encode mode and the tool escapes them to &lt;, &gt; and &amp; so they display as text instead of markup.

What's the difference between &amp;amp; and &amp;#38;?

Both represent an ampersand — &amp; is the named entity and &#38; is the numeric one; this tool can output either.

How do I decode double-encoded text?

Run the decoder twice — the first pass turns &amp;amp; into &amp;, the second into &.

How do I show code in HTML without it rendering?

Encode it first so the tags become entities, then paste the encoded version into your page.

Named or numeric entities — which should I use?

Named entities are more readable for the common characters; numeric entities work for any character, including emoji and other Unicode.
