Frequently Asked Questions
Everything you need to know about the HTML Entity Encoder / Decoder.
How does the HTML entity tool work?
Paste text to encode special characters into HTML entities, or paste entities to decode them back to text. Change either field and the other updates instantly.
Is it free?
Completely free, no sign-up, downloads, or limits.
What is an HTML entity?
A way to represent characters that have special meaning in HTML (like <, >, and &) or that are hard to type, using codes such as <, &, or ©.
What types of entities can it decode?
Named entities (&, ©, ), decimal numeric entities (©), and hexadecimal entities (©).
Can I choose what gets encoded?
Yes. Encode just the HTML-unsafe characters by default (&, <, >, ", '), or switch to "All non-ASCII" to encode every character above ASCII 127 for maximum safety.
Does it handle emoji and accents?
Yes, full Unicode is supported, so accented letters, symbols, and emoji convert correctly in both directions.
Is decoding safe?
Yes. The tool decodes using a lookup table and String.fromCodePoint() — it never assigns to innerHTML or renders pasted markup as live HTML, so there is no risk of script execution.
Why escape HTML characters?
Escaping prevents characters from being interpreted as markup, which keeps content displaying correctly and helps avoid injection issues on web pages.
Is my data sent anywhere?
No. Everything is processed locally in your browser; nothing is stored or sent to any server.
Does it work on mobile?
Yes, fully responsive; both fields and options fit the screen without overflow at any viewport width.
