Minified or messily-indented code is hard to read and harder to debug. This reformats HTML, CSS, JavaScript or SQL into clean, consistently indented code, and can also minify it back down when you want the smallest possible output. It all runs in your browser.

Good to know

Four languages, one toolHTML, CSS, JavaScript and SQL each have their own rules, so pick the right mode for clean results.
Formatting only, not fixingIt re-indents and re-spaces; it does not correct bugs or change what the code does. Broken syntax stays broken, just tidier.
Minify is nearly one-wayBeautifying minified code restores a readable layout, but original names and comments that were stripped are gone for good.
Mind your house styleIndent size and brace placement follow sensible defaults; match them to your project's style if it differs.
