What is HTML Entity Encoder?

An HTML entity encoder converts special characters into their HTML entity equivalents so they display correctly on web pages without being interpreted as HTML code. Characters like <, >, &, and " have special meaning in HTML — if you want to display them as visible text rather than markup, they must be encoded as <, >, &, and ". This tool also handles the reverse — decoding entity strings back to readable characters for editing.

How It Works

The encoder scans your input character by character, identifying characters that have reserved meanings in HTML. It replaces each with the corresponding named entity (like &) or numeric entity (like &). The decoder does the reverse — recognizing entity patterns and converting them back to the original characters. Both named entities (like © for ©) and numeric entities (decimal and hexadecimal) are supported.

•Converting special characters in database content for safe HTML output
•Decoding HTML entities in API responses or scraped content back to readable text
