How this CSS formatter helps

Before and after formatting

Paste compact, copied, or hard-to-read CSS into the input pane. FormatPaste cleans common paste artifacts first, then formats the code into readable output that is easier to scan, debug, share, or copy into your editor.

Common CSS formatting use cases

Use it for quick snippets from documentation, AI chat output, Stack Overflow answers, config examples, API responses, old files, minified blocks, and code that picked up line numbers or markdown fences while being copied.

Safe paste reminder

FormatPaste is built for speed, but you should avoid pasting passwords, API keys, tokens, private keys, recovery codes, customer data, or other secrets into any online formatter. Use local tools for sensitive code.

CSS formatting example

Before

.nav{display:flex;gap:12px;align-items:center}.nav a{color:#333;text-decoration:none}.nav a:hover{color:#0070f3}@media (max-width:600px){.nav{flex-direction:column}}

After

.nav {
  display: flex;
  gap: 12px;
  align-items: center;
}
.nav a {
  color: #333;
  text-decoration: none;
}
.nav a:hover {
  color: #0070f3;
}
@media (max-width: 600px) {
  .nav {
    flex-direction: column;
  }
}

When to use a CSS formatter

Unminify CSS from production sites

Minified stylesheets put every rule on one line. Formatting expands them into one declaration per line so you can find the rule that sets a color, margin, or breakpoint.

Clean styles copied from DevTools

Rules copied from the browser inspector, design tools, or CSS generators come in different shapes. Formatting gives them consistent spacing before you paste them into your stylesheet.

Review media queries and breakpoints

Indented media queries make it clear which rules apply at which screen size, which helps when a layout breaks only on mobile.

Beautify CSS before sharing

Paste formatted CSS into bug reports, code reviews, or tutorials so readers can follow each selector and property without scrolling sideways.

CSS Formatter FAQ

How do I format CSS online?

Paste CSS into the input area and copy the formatted output.

Can it format minified CSS?

Yes. It can expand compact CSS into readable rules.

Is this CSS formatter free?

Yes. It is free for quick CSS formatting.

Does it support media queries and modern CSS?

Yes. Media queries, custom properties (CSS variables), grid and flexbox declarations, and nested at-rules are formatted with each rule and declaration on its own line.

Can it format SCSS or Less?

This page uses a CSS parser. Plain SCSS that is also valid CSS will format, but SCSS-only features such as mixins and nested rules may return a parse error.

Will formatting change how my styles apply?

No. Only whitespace and line breaks change. Selectors, property values, and the order of rules stay the same, so the cascade behaves exactly as before.
