JavaScript Escape / Unescape

JavaScript string escaping is the process of adding backslashes before special characters so they can be safely included in string literals. Characters like quotes, backslashes, and newlines must be escaped to prevent syntax errors.

You need to escape strings when embedding user input in JavaScript code, creating JSON manually, inserting strings into HTML event handlers, or when a string contains special characters that would break the syntax.

This tool escapes single quotes, double quotes, backslashes, newlines, carriage returns, tabs, null bytes, and Unicode characters outside the basic ASCII range.

Escape converts special characters into their backslash-prefixed equivalents (e.g., a newline becomes \n). Unescape reverses the process, converting escape sequences back into their original characters.
