Should I encode everything or just special characters?

Just the reserved ones: , &, quotes in attributes, and non-ASCII characters if your charset is uncertain. Over-encoding makes source unreadable without benefit.

Does this prevent XSS attacks?

Encoding output is a key defense, but proper XSS prevention also requires context-aware escaping (HTML, attribute, JavaScript, URL contexts differ) and Content Security Policy headers.

Escaped Markup

About this tool

The HTML Entity Encoder converts special characters into HTML entities — turning < into < and & into &. Essential when displaying code samples in web pages, writing email templates, or safely rendering user content.

Unencoded angle brackets and ampersands can break page markup or, worse, enable cross-site scripting. Encoding user-supplied text before injecting it into HTML is a fundamental web security practice.

How to use

1Paste HTML or text containing special characters.
2Characters like <, >, &, and quotes are escaped automatically.
3Copy the safe escaped markup.

Frequently asked questions

Characters like <, >, and & have special meaning in HTML. Encoding them tells the browser to display the literal character instead of interpreting it as markup — critical when showing code examples.
