Free CSS Beautifier Online
The CSS Beautifier expands minified or messy CSS into a clean format with proper indentation, line breaks, and spacing.
When a production stylesheet from a CDN is compressed onto a single line, the rules become impossible to read or debug. Pasting that blob into the editor expands the file instantly, letting you set the indent size and split multi-selector rules onto their own lines so a human can read the code.
Using the CSS Beautifier, Step by Step
- Drop the CSS in: paste a minified stylesheet into the editor on the left, drag a .css file onto the input panel, or click Upload CSS in the toolbar.
- Pick the format options: choose 2 spaces, 4 spaces, or tab for indent, toggle Selector Per Line, Blank Between Rules, and Sort Properties to match how your team writes CSS.
- Read the stats bar: live counts show input size, output size, byte difference, and the line-count change so you can tell what expanded.
- Take the result out: Copy puts the readable CSS on your clipboard, Download saves it as a .css file you can hand to a teammate.
What You Can Do with AIFreeForever's CSS Beautifier
Indent Size Picker
Switch between two spaces, four spaces, and a real tab so the output matches the rest of your project layout.
Selector Per Line

Property Sorting
Alphabetic sorting inside every rule block keeps a noisy diff small when only one declaration changes.
Nested At-Rules
Media queries and keyframes nest correctly so the inner rules sit at the right visual depth for reading.
Live Stats Bar
Input size, output size, byte difference, and line-count changes update as you type new characters.

Who Can Use Our CSS Beautifier
- Frontend developers: expand a minified vendor stylesheet to find the exact rule that breaks a layout.
- QA engineers: reformat the CSS shipped by a build pipeline so a regression check can read the visual diff.

Most flexible way to reformat a minified stylesheet
Instead of forcing a fixed format, the engine exposes four layout passes you control per paste so the output matches your project style.
Four Pass Controls
Indent, selector split, blank lines, and property sort each toggle on their own so the output looks the way your team writes.
Handles Real Stylesheets
Media queries, keyframes, and other at-rules indent at the right depth so the inner rules read correctly.
Stays in Your Browser
CSS Beautifier runs completely locally so a proprietary layout never leaves your machine.
