JavaScript Beautifier
Paste minified or messy JavaScript to get readable, indented output. Runs entirely in your browser — nothing is uploaded anywhere.
This is a lightweight, brace-depth-based formatter — good for getting a readable first pass on typical code. It won't match every stylistic choice a dedicated formatter like Prettier would make, so review the output before committing it.
Need a real linting and formatting setup?
We wire up ESLint, Prettier and CI checks properly — not just a one-off paste tool.
