Before you start
Encode special HTML characters or decode semicolon-terminated HTML named entities and decimal or hexadecimal numeric references once. Output remains plain text, so decoded tags and scripts are never executed.
How to use this tool
- Paste text to encode or semicolon-terminated HTML entities to decode.
- Choose Encode or Decode. The non-ASCII option applies only when encoding.
- Check the plain-text result, then copy or download it; unknown entity names remain unchanged.
Supported inputs and limits
Pasted text is limited to 1 MiB; review the result before using it.
Unknown entity names remain unchanged; invalid numeric scalar values report an error.
Legacy C1 numeric references follow HTML mapping (for example, € becomes €).

When something does not work
Use the documented input format and keep values within the displayed limits. Review the result before using it in another document or application. Editing the input marks the previous result as stale; a failed run clears it.
Frequently asked questions
Are my files uploaded?
No. Files and tool input are processed in your browser. Moving around the site can keep a temporary workspace in the same tab. Refreshing or closing the tab clears it, so download results you want to keep.
What should I check in this result?
Encode special HTML characters or decode supported named and numeric entities exactly once. The output stays text; decoded tags and scripts are never executed.
