Format and beautify HTML, CSS, and JavaScript instantly in your browser. Turn minified or messy code into clean, readable output with the indentation style you prefer. No sign-up, nothing stored.
A code beautifier (also called a formatter or pretty-printer) takes source code and rewrites its whitespace — indentation, spacing, and line breaks — so it is consistent and easy to read. It is the opposite of a minifier: where a minifier strips formatting to shrink file size, a beautifier restores structure to make code understandable.
This tool supports JavaScript, CSS, and HTML, and lets you choose between 2 spaces, 4 spaces, or tabs for indentation. Formatting runs entirely on your device, so even sensitive code never leaves your browser.
