Frequently Asked Questions
Everything you need to know about our process, pricing, and technical capabilities.
See Full FAQHTML character entities are special codes that represent characters in HTML/XML. For example, < represents <, © represents ©. They're used to display special characters that might otherwise be interpreted as code.
Encode characters when: 1) Displaying user input in HTML to prevent XSS attacks, 2) Including special characters like & in HTML content, 3) Ensuring compatibility with older systems, 4) Storing text in XML/HTML format.
Named entities use words (©), decimal uses numbers (©), and hexadecimal uses hex numbers (©). Named entities are readable but limited. Decimal/hex can represent any Unicode character but are less readable.
No! Only encode what's necessary. Always encode & in HTML content. Encode quotes in attribute values. Modern HTML5 supports most Unicode characters directly, so encoding everything is usually unnecessary.
Yes! Encoding user input is a key XSS prevention technique. Converting < to < prevents browsers from interpreting malicious scripts. However, use this as part of a comprehensive security strategy, not the only defense.
Use named entities for common characters (better readability). Use decimal for uncommon characters (universal support). Use hexadecimal when working with Unicode code points (matches Unicode notation).
Yes! Emoji can be encoded to decimal or hexadecimal entities. For example, 😀 becomes 😀 or 😀. However, modern browsers support emoji directly, so encoding is usually unnecessary.
This tool decodes HTML/XML entities. For JavaScript escape sequences (\u003C), use a JavaScript-specific tool. HTML entities and JS escapes are different formats.
Yes! All processing happens in your browser. However, remember that encoding is just one step in security. Always validate and sanitize user input on the server side too.
Yes! Upload HTML/XML files of any size. The tool processes everything instantly in your browser without sending data to servers.
