Encode & < > and quotes as named entities like & or as numeric references. Named output is easier to read in templates; numeric covers characters that have no common name. Switch modes without re-pasting when you are preparing a snippet for a CMS or an email.
Special-chars mode is what you usually want for XSS-safe snippets: the markup-sensitive characters, not the whole alphabet. All-characters mode turns every code point into an entity when a picky consumer rejects raw Unicode.
A sandboxed preview shows how the decoded HTML would look, so you can catch a leftover < that should have been a real tag — or the opposite. Entity and character counts sit beside the output.
Encode and decode run in the browser. Draft HTML, unreleased copy, and snippets with tokens never upload. There is no account and no file picker.
Drop markup, a plain sentence, or a string full of & sequences. You do not need to upload a document.
Encode turns characters into entities. Decode turns entities back into characters so you can read or edit the real text.
Pick named or numeric entities, then special characters only or all characters. The output and the preview update together.
Confirm the rendered preview matches what you intended, then copy the encoded or decoded string. Nothing is stored on a server.
