How to use

This tool belongs to the “Code & markup formatting” category.

  1. 1Paste your source and open the matching formatter — HTML, CSS, JS, SQL, PHP and more each have their own page.
  2. 2Format first to read the structure and catch syntax errors, then minify for the version you ship.
  3. 3Need it as a string literal? Use the HTML-to-JS/PHP/C# converters, which escape quotes and line breaks for you.

Your input is processed locally in the browser whenever possible. We do not store it.

Frequently asked questions

What is the difference between format and minify?

Formatting expands code into indented lines for readability; minifying strips whitespace and comments to reduce size.

Will it change what my code does?

Only whitespace, line breaks and comments are touched. With JavaScript that relies on automatic semicolon insertion, test the minified output before shipping.

Is my code uploaded?

Formatting and minifying run client-side. Nothing is written to server logs.
