HTML Encoder Online — Escape HTML Special Characters

Encode HTML special characters online by converting text into safe HTML entities locally in your browser.

About this tool

This HTML encoder uses the browser DOM to escape text so characters such as angle brackets and ampersands can be displayed instead of interpreted as markup.

How to use

  1. Paste the text or HTML-like content to escape.
  2. Run the encoder to generate HTML entities.
  3. Copy the result into source code, documentation or a template.

Features

  • Escapes markup-sensitive characters with browser-native rules.
  • Preserves the readable text represented by the input.
  • Runs locally without uploading content.

Common use cases

  • Show an HTML example inside a web page.
  • Prepare literal text for an HTML template.
  • Prevent pasted markup from being interpreted as elements.

Common issues and tips

  • Encoding text is not a complete defense for every JavaScript, CSS or URL context.
  • Already encoded entities may become double-encoded if processed again.

Privacy

HTML encoding runs locally in your browser. The input is not uploaded to Tools12345.

Frequently asked questions

Which characters are escaped?

The browser escapes characters that would otherwise be interpreted as HTML markup, including angle brackets and ampersands.

Is this the same as sanitizing HTML?

No. Encoding displays input as text; sanitizing selectively allows safe markup and requires context-aware rules.

Can I decode the result?

Yes. Use the related HTML Decoder to turn recognized entities back into text.
