HTML Entity Encoder & Decoder

Encode HTML special characters to entities or decode entities back to characters. Choose between encoding all characters or only the special ones — everything runs in your browser.

Encode & decode HTML entities

Type HTML in the top box or encoded entities in the bottom box.

What are HTML entities?

HTML entities are special sequences that represent characters which have special meaning in HTML. For example, &lt; represents < and &amp; represents &. Without encoding, browsers would interpret these characters as HTML markup rather than displaying them as text.

Special vs. all encoding

Special-only mode encodes only the five characters that are reserved in HTML: &, <, >, ", and '. Encode all mode converts every character to its numeric entity (&#NNN;), which is useful for obfuscating email addresses or ensuring maximum compatibility with legacy systems.

Common use cases

Use HTML entity encoding when displaying user-generated content to prevent XSS attacks, embedding code snippets in blog posts, or preparing text for HTML email templates. This tool processes everything in your browser — your content is never sent to a server.
