## Minified code, made readable again

[Beautify](https://www.jpkc.com/tools/beautify/) takes compressed, single-line, or deliberately obscured source code and returns it cleanly indented and formatted. You know the situation: a `min.js` from a build, a CSS blob pulled from the DevTools inspector, or an HTML fragment without a single line break — all technically correct, but nearly impossible for a human to read. Beautify reverses that.

You paste the code into the editor, click **Beautify** (or press Ctrl+Enter), and get formatted code back — right in the same editor, ready to copy or download. The tool detects the language automatically; you can also pin it to JavaScript, CSS, or HTML when needed.

Beautify is built for everyone who works with someone else's or shipped code: **developers** who need to make sense of a minified production file; **frontend people** who want copied CSS or HTML in a consistent shape; and anyone who has to make a snippet from a console, a bug report, or a library readable before working with it.

## What Beautify does

The features fall into three groups:

- **Formatting** — JavaScript, CSS, and HTML are re-indented and wrapped. The options control indentation (tabs or 2 to 8 spaces), allowed blank lines, line-wrap length, brace style, and eleven detail toggles such as comma-first, break chained methods, or keep array indent.
- **Unpacking and deobfuscation** — with the **Detect packers** option, the tool recognizes common JavaScript packers and unpacks them before formatting: the classic P.A.C.K.E.R. format (`eval(function(p,a,c,k,e,d)…`), URL-encoded code, and MyObfuscate. This is pattern-based — there's no AI involved, just the reversal of known packing schemes.
- **Input/output** — upload a file at the click of a button (`.js`, `.css`, `.html`, `.json`, and more), copy the result to the clipboard, or download it as a file. The editor (CodeMirror) brings syntax highlighting and line numbers; you can switch to a plain text field if you prefer.

JSON and JSONP are handled by the JavaScript formatter — valid JSON is valid JavaScript, so it gets indented cleanly. That isn't a dedicated JSON validator, though; for that there's the JSON Editor tool.

## Architecture and privacy

Beautify runs **entirely in your browser**. The code you paste or upload is not sent to any server — the formatting and unpacking are done by JavaScript libraries (js-beautify and the unpackers) locally on your machine. File uploads are read locally too. That makes the tool safe for proprietary or confidential code: it never leaves your browser.
