Encode text as one quoted JavaScript literal without parsing or executing it.
Submit the example or replace it with your own input. Source is parsed but never executed.
Explicit static behavior
The encoder escapes the selected quote, backslashes, control characters, line separators, and lone UTF-16 surrogates while preserving valid surrogate pairs.

This is a direct character encoder. It never decodes by evaluation and its output can be checked by a parser as syntax.
Tool Swim parses source as standard ECMAScript inside a disposable Web Worker with a 2,000 ms deadline. It never calls eval, Function, imported modules, or user code.
Source and results stay in the current browser tab. The public tool makes no API request, stores no preset, and does not require an account or telemetry.
