Convert text and HTML snippets into safe HTML entities for browser rendering, code examples, CMS content, and XSS-aware output escaping.
HTML Entity Encoder transforms text for safer use in web, API, configuration, spreadsheet, or serialized-data workflows. It reports conversion counts, output size, syntax issues, and a data integrity score.
Escaping improves format safety, but it does not replace input validation, authentication, authorization, or contextual security review.
Example input: <div>Hello & Welcome</div>. The result area shows the converted value plus integrity, size, and validation metrics.
Processing happens locally in the browser. The tool calculates character analysis, syntax validation, output byte size, expansion, and format-specific warning signals.
Escaping improves format safety, but it does not replace input validation, authentication, authorization, or contextual security review.
Paste HTML or text and encode it. Reserved characters such as angle brackets and ampersands are converted into browser-safe entities.
Use entity encoding before displaying untrusted text in an HTML page, CMS block, or code example.
Entity encoding helps prevent markup from being interpreted as HTML when user-provided content is rendered as text.
Named entities use readable names like amp, while numeric entities use decimal or hexadecimal code points.
Yes, but the result displays the HTML source as text rather than rendering it as a page.
