Did You Know?
HTML entities always start with an ampersand and end with a semicolon.
HTML entity encoding is a technique used to represent characters that have special meaning in HTML or characters that may not be available in a standard character set. Since characters like '<' and '>' are used to define HTML tags, using them as literal text requires conversion into entities like < and >. This process ensures the browser treats the characters as data rather than markup, maintaining both the intended visual layout and the security of the web application.
Best Practice
Always encode user-generated content before rendering it in an HTML context to block scripts.
Incorporate HTML encoding when handling any dynamic user input that will be rendered on a page to mitigate injection attacks. For technical writers and developers, use encoding to safely embed code examples within documentation. When working with APIs that return HTML-encoded strings, use our decoder to quickly verify the raw content during the debugging phase.
Q: What is the difference between named and numeric entities? A: Named entities use aliases like &, while numeric entities use the character's Unicode position, such as &.
Q: Does this tool protect against XSS? A: Yes, by encoding characters like < and >, you prevent the browser from executing malicious scripts embedded in the text.
Q: Can I decode entities from an XML file? A: Yes, most HTML entities are compatible with XML, and this tool handles standard character references used in both formats.
