When to use a CSS formatter
Reformatting helps when you copy compressed CSS from a built bundle, inherit a stylesheet with inconsistent spacing, or want to read a rule before editing it. Consistent indentation makes selectors and nesting obvious and keeps diffs clean.
Frequently asked questions
Is this CSS formatter free?
Yes — it's a completely free online CSS formatter and beautifier with no sign-up and no limits. Format and indent as much CSS as you like.
Is my CSS uploaded to a server?
No. This is a no-upload tool — your CSS is formatted entirely in your browser, so the code never leaves your device. It's safe for private or internal stylesheets.
What does the CSS beautifier do?
It puts each rule and declaration on its own line, normalizes spacing around braces, colons, and semicolons, and re-indents everything so minified or messy CSS becomes readable.
Can I choose the indentation?
Yes — pick 2 spaces, 4 spaces, or tabs. Your choice is remembered in your browser for next time.
Does it work with SCSS or Less?
It handles most SCSS and Less syntax well for indentation and tidying, since the structure is CSS-like. It formats rather than compiles — it won't expand nesting or variables.
Does it expand minified CSS?
Yes. Paste a single-line or minified stylesheet and it expands it back into a properly indented, readable set of rules.
Does it work offline and on mobile?
Once the page has loaded it runs locally, so it keeps working on a flaky connection, and the layout is fully responsive on phones and tablets.
