What we do

Restore Readability

If you inherited a messy codebase or need to debug minified code, our beautifier automatically untangles the wall of text and makes it human-readable again.

Syntax Highlighting

We integrated the premium CodeMirror engine to provide real-time JavaScript syntax coloring and active highlighting, giving you a top-tier developer experience.

Perfect Indentation

Properly formatted code is essential for finding logic bugs. Our tool cleanly separates nested functions, loops, and conditions, applying perfect 2-space or 4-space indentations.

Handle Massive Files

Working on a massive project? Click the "Load .js" button to instantly upload entire unformatted script documents directly from your computer and beautify them in milliseconds.

Industry Standard Engine

We use the highly respected js-beautify engine—the exact same parsing and formatting technology that powers leading text editors like VS Code and Sublime Text.

100% Secure & Private

Your proprietary scripts and logic are completely safe. We never upload, store, or view your source code. The entire formatting process runs securely right on your local device.
