HTML Beautifier
Re-indent minified or pasted HTML, including inline <style> and <script> blocks.
How it works
JavaScript Beautifier
Make a minified bundle readable again. Line breaks, indents and braces come back, in your choice of indent and brace style. Built on js-beautify.
Paste or type to begin. Everything runs in your browser.
- 01
Paste JavaScript (minified bundles work), drop a .js file onto the input, or load the sample.
- 02
Choose an indent and whether braces go on the same line or a new one.
- 03
Copy the readable code or download it as a .js file.
Good to know
- It unpacks some packed code and \xNN-escaped strings, which helps when you're checking a suspicious script.
- Variable names stay as the minifier left them (a, e, t). Only a source map gets the originals back.
FAQ
Frequently asked questions
Does it work with TypeScript or JSX?
Plain TypeScript and JSX usually format well. Very new syntax may trip it up, since the tool targets JavaScript.
Will formatting change how the code runs?
No. Only whitespace and line breaks change.
