HTML Encode / Decode

HTML encode and decode entities online. Escape markup for safe display, or decode entities when reading scraped or templated HTML—free in your browser.

Escape HTML for safe display or decode entities when reading templated markup. Mode switches Encode and Decode on the same page.

About HTML Encode / Decode

Raw angle brackets in user content break pages and create XSS risk when rendered as HTML. Encoding turns them into entities browsers treat as text.

Decode is useful when you inherit entity-heavy strings from CMS exports, emails, or scrapers and need the readable form.

One hub covers both directions so docs and debugging stay in a single workflow.

How to Use HTML Encode / Decode

  1. Paste the HTML or text fragment.
  2. Choose Encode or Decode under Mode.
  3. Run the tool.
  4. Copy the escaped or restored string.

Encode before inserting untrusted text into HTML templates; decode only when you trust the source.

Common Use Cases

Safe snippets

Escape sample markup for documentation pages.

CMS cleanup

Decode entity soup from exported content.

Form tests

Prepare encoded fixtures for HTML sanitizer tests.

Tips and best practices

HTML entity tools sit next to URL encoding and formatters for everyday front-end chores.

Frequently Asked Questions

Quick answers about how this tool works and when to use it.

Does Encode stop XSS by itself?

Encoding helps for HTML text context, but apps still need proper sanitization and context-aware escaping.

Will Decode break my tags?

Decode restores entities to characters; review output before pasting into a live page.

Is this the same as URL encode?

No. HTML entities and percent-encoding solve different problems—use the URL hub for query strings.

Can I encode a full HTML document?

You can, but usually you encode the untrusted fragment, not the entire template.

What does Html Encoder create?

Html Encoder creates html encoder results you can copy into forms, fixtures, demos, or design files. Adjust the on-page options, generate a batch, and regenerate until the output fits your scenario.
