JavaScript String Escaper

Turn any text into a safe JavaScript string literal, or decode an escaped literal back into readable text. Handles quotes, newlines, control characters, and Unicode — everything runs in your browser, so your input never leaves the page.

What do you want to do?

Choose the quote that will wrap the literal, or bare escapes to paste the body yourself. <script> stays safe because nothing is rendered as HTML.

Input

text

Everything is processed locally. Ctrl/ Cmd + Enter copies the result.

Output

What gets escaped

Escaping protects a backslash, the surrounding quote character, and the short escapes \n, \r, \t, \b, \f, and \v. Remaining control characters use \xHH, and the JavaScript line/paragraph separators \u2028 and \u2029 are always escaped. Enable the Unicode option to turn every non-ASCII character into a \uXXXX escape when you need pure ASCII output.

Unescaping understands the full JavaScript string grammar: \xHH, \uHHHH, \u{...}, line continuations, and identity escapes. Legacy octal escapes are rejected with an explanation because they are invalid in strict mode.
