Text to HTML Safe Converter - Online Escape for Web

HTML escaping is the process of converting special characters into their corresponding HTML entities so they display correctly in web pages instead of being interpreted as HTML code. For example, < becomes <. Without escaping, special characters can break your page layout, cause rendering errors, or create XSS (Cross-Site Scripting) vulnerabilities that allow attackers to inject malicious scripts into your website.

The five critical characters that should always be escaped are:

• & → & (ampersand — always escape first!)
• < → < (less-than / opening tag)
• > → > (greater-than / closing tag)
• " → " (double quote — important inside attributes)
• ' → ' or ' (single quote — important inside attributes)

Additionally, the forward slash (/) may need escaping as / in certain contexts like inside <script> tags.

HTML escaping replaces characters like <, >, and & with entities for safe display in HTML documents. URL encoding (also called percent-encoding) replaces unsafe characters with %-prefixed hex codes for safe inclusion in URLs. For example, a space becomes %20 in a URL but may become   in HTML. They serve different purposes and are not interchangeable.

HTML escaping is a critical first line of defense against XSS, but it's not always sufficient on its own. You must escape data in the correct context: HTML body, HTML attributes, JavaScript, CSS, and URLs each require different escaping strategies. For robust protection, combine output escaping with Content Security Policy (CSP) headers, input validation, and modern frameworks' built-in XSS protections. Never rely solely on HTML escaping when inserting user data into <script> tags or event handlers like onclick.

Once you have the escaped HTML from this tool, you can safely insert it directly into your HTML source code. For example, if you want to display <div class="example"> on your page, paste the escaped version <div class="example"> into your HTML file. The browser will render it as readable text rather than interpreting it as an actual HTML element. This is especially useful for code snippets, tutorials, and user-generated content.

Yes! Use the Unescape mode in this tool. It converts HTML entities like <, >, &, ", and numeric entities back to their original characters. This is useful when you receive escaped HTML and need to read or process the original text. The unescape process uses the browser's built-in HTML parser for accurate, reliable decoding.

Yes. This tool works with all Unicode characters, including emoji 😊, Chinese characters 中文, Arabic نص, Cyrillic текст, and special symbols. Non-ASCII characters are preserved as-is in both escape and unescape modes. If you need to convert non-ASCII characters to numeric HTML entities (e.g., 中 for 中), you may need an additional encoding step — this tool focuses on the critical HTML-special characters.

The ampersand & is the prefix character for all HTML entities. If you escape other characters first (e.g., < becomes <), the newly created & in < would then be escaped again to <, resulting in double-escaping. By always escaping & first, you prevent this cascading error. This is why our tool processes the ampersand before any other character.

Double-escaping occurs when already-escaped text gets escaped again, turning < into <. This makes the text display incorrectly (showing raw entity codes instead of the intended characters). To avoid it, always track whether your data has been escaped, and use the Unescape mode to revert double-escaped content before re-escaping. Our tool's "Swap" feature lets you quickly verify by unescaping the output to check correctness.
