About this tool

DevCove HTML Entity Encoder / Decoder helps frontend developers, CMS editors, and template authors escape or unescape HTML safely. Convert characters to named entities such as ©, decimal forms such as ©, or hexadecimal forms such as ©. Decode mixed entity strings back to Unicode text while preserving spaces and line breaks. Batch mode handles logs, CSV fields, and migration lists line by line.

How to use this tool

Use this tool when CMS content, templates, or logs contain escaped HTML characters:

  1. Choose Encode to escape text for HTML, XML-ish templates, or CMS fields; choose Decode to turn entities back into readable characters.
  2. Select named, decimal, or hex entity style for encoding. Named is usually easiest to read; numeric forms are useful for uncommon symbols.
  3. Enable quote encoding when preparing attribute values. Disable it when escaping HTML text nodes only.
  4. Review the text preview panel to see how decoded characters will look, including symbols such as © and non-breaking spaces.
  5. Use batch mode to convert many lines from logs, exports, or spreadsheets without changing line breaks.
  6. Remember that decoding only produces text—it does not sanitize HTML for safe insertion into a page.

FAQ

What is the difference between named and numeric entities?

Named entities use readable names such as ©. Numeric entities use code points such as © or ©. Browsers treat them the same after decoding.

Will this sanitize unsafe HTML?

No. Encoding helps prevent accidental parsing; decoding reveals characters but does not remove scripts or unsafe markup. Sanitize separately before rendering untrusted HTML.

Are line breaks preserved?

Yes. The tool converts line by line in batch mode and keeps \n characters in single-value encode/decode flows.

When should I encode quotes?

Encode quotes when placing values inside HTML attributes. For plain text nodes, < and > are usually the critical escapes.

Can I decode mixed entity formats in one string?

Yes. The decoder accepts named, decimal, and hex entities in the same input.

Is my content uploaded?

No. All encoding and decoding runs locally in your browser.
