Concept

HTML entity conversion is for output formatting

Use this tool to convert `<`, `>`, `&`, and `"` between readable text and entity form when characters should be shown in HTML safely.

If a literal `<`, `>`, `&`, or `"` is inserted into HTML content, it may be parsed as markup; encoding turns these characters into `&lt;`, `&gt;`, `&amp;`, and `&quot;` so they render as text.

If you receive text packed with entities and need the original characters for editing or reuse, decode back to plain text on the output side.

Typical usage

Use encode to display code snippets, templates, or copied examples safely, and decode to inspect entity-heavy text in its original characters.

Security checkpoint

Display escaping is different from XSS defense: entity conversion is not a full HTML sanitizer.

Limits

This tool performs in-browser text conversion only and does not replace security hardening, HTML linting, or content sanitization.

For XSS prevention, use output encoding rules with a server-side sanitizer or trusted allowlist; use this converter for presentation-safe text handling, not as a security boundary.

How to use

  1. 1 Put plain text or HTML entities in the matching field.
  2. 2 Use Encode for plain text or Decode for entity text.
  3. 3 Check the converted result, then copy it.

Common use cases

  • Escape HTML special characters
  • Read entity codes as text
  • HTML entity decode online
  • Convert multilingual characters to entities

Frequently asked questions

Which characters does the HTML entity encoder convert?

Characters that need safe HTML display, such as angle brackets, ampersands, some spacing characters, and multilingual text, are converted to numeric entities.

Can I use this as an HTML entity decoder?

Yes. Put the entity text in the entity field and run Decode to read the original text through the browser's HTML parser.

Can I paste a full HTML document?

This tool is for text and entity conversion. It does not validate HTML structure or provide security filtering.
