Code Beautifier

About the Code Beautifier

Code Beautifier does the opposite of the minifier — it takes a single-line, whitespace-stripped blob of JS, HTML or CSS and restores proper indentation, line breaks and readability.

How to use

1. Pick the language tab.
2. Paste the minified code.
3. Click Beautify and copy the indented output.

Benefits & key features

• Choice of indent size (2 spaces, 4 spaces, tabs).
• Handles most minifiers' output including UglifyJS, Terser and CleanCSS.
• Useful for auditing third-party scripts and inline widgets.
• Runs locally, so proprietary code never leaves the browser.

Pro tip

If the beautified output still looks mangled, the source was obfuscated (variable names replaced with gibberish). Beautifiers restore whitespace, not semantics.

Why choose toolsfy for Developer tools?

Developers already have editors, linters and one-off scripts that do half of what these utilities do — but nobody wants to paste a JWT into a random cloud decoder, or send an AES-encrypted sample through someone else's server. toolsfy's dev utilities are deliberately tiny, zero-dependency and 100% client-side so they can become part of a muscle-memory workflow you actually trust with production data.

Common use cases

• Full-stack developers formatting a gnarly production JSON payload to figure out which field the front-end is mis-parsing.
• DevOps engineers minifying a snippet of JavaScript or CSS inline during a code review, without reaching for a Node build step.
• Security engineers hashing or Base64-encoding a small test vector for a quick regression check on an authentication flow.
