How do I escape a quote in a JavaScript string?

Inside a single-quoted string escape ' as \'; inside a double-quoted string escape " as \"; inside a template literal escape the backtick ` as \` and ${ as \${. This tool escapes all quote styles plus the backslash so the result is safe in any JS string literal.

What characters does JavaScript string escaping cover?

The backslash itself (\\), the three quote characters (' " `), and the whitespace controls newline (\n), carriage return (\r) and tab (\t). Backslash must be escaped first, otherwise it would corrupt the following escape sequences.

Is JavaScript escaping the same as JSON escaping?

They overlap but differ. JSON only allows double-quoted strings and a fixed set of escapes; JavaScript also has single quotes, template-literal backticks and ${} interpolation. Use JavaScript Escape for code you paste into a .js file, and JSON Escape for values going into a .json document.

Does this run on a server?

No. Escaping and unescaping happen entirely in your browser with plain JavaScript — no upload, no logging. Safe for embedding API keys or config strings into source.

Can I unescape a JavaScript string back to plain text?

Yes. Click Unescape and the tool reverses the literal escapes — \n becomes a real newline, \' becomes ', and \\ becomes a single backslash — recovering the original text.

JavaScript Escape & Unescape — safe JS string literals

Embedding arbitrary text in JavaScript source means escaping the characters that would otherwise terminate the string or start an interpolation. Unlike JSON, JavaScript has three string forms — single quotes, double quotes and backtick template literals — each with its own quote to escape. This tool escapes for all of them, and reverses the process, entirely in your browser.

What gets escaped

Character	Escaped as
Backslash `\`	`\\` (escaped first)
Quotes ' " `	\' \" \`
Newline / return / tab	`\n` / `\r` / `\t`

Template-literal gotcha

In backtick strings the sequence $${} begins interpolation. If your text contains a literal $ followed by {, escape the backtick form or switch to a quoted string — otherwise the runtime tries to evaluate the contents as an expression.
