HTML Entity Encoder

FAQ

Which characters are always encoded?+

& < > " and ' are always escaped. Printable ASCII otherwise stays as-is. Non-ASCII and control characters become entities.

Named or numeric entities?+

Common characters prefer named forms (&eacute;, &mdash;, &copy;). Others use decimal numeric entities (&#NNNN;).

Is my data uploaded?+

No. Encoding runs entirely in your browser.

When do I need HTML entities instead of UTF-8?+

Entities help when HTML parsers treat <, &, or quotes as syntax. UTF-8 in the document is fine for modern pages, but entities are still common in templates, RSS, and legacy CMS exports.

Does this escape every Unicode character?+

Printable ASCII outside the reserved set stays literal. Other code points become named entities when known, otherwise numeric &#NNNN; or &#xHH; forms.
