Cleaning up a different kind of file? Static.app has a matching tool for each format:
How Static.app's CSS Formatter compares
All five tools beautify CSS for free in the browser, so the honest differences are in formatting options, whether minify is built in, and what you can do with the file after you clean it up.
| Static.app | Beautifier.io | CSSPortal | CodeBeautify | FreeFormatter.com | |
|---|---|---|---|---|---|
| PriceEvery tool here formats CSS at no cost with no signup. | Free | Free | Free | Free | Free |
| ProcessingStatic.app, Beautifier.io and CSSPortal run entirely client-side, so code never leaves your device. CodeBeautify does not state where it processes. FreeFormatter processes some tools on its servers (held briefly in RAM). | In your browser | In your browser | In your browser | Not stated | Server-side (RAM only) |
| Formatting optionsThis is where we lose: our formatter applies one clean style with no knobs, while CSSPortal and Beautifier.io expose deep controls. | Fixed output | Many (indent, wrap, braces) | Extensive (indent, sort, shorthand) | Indent width choices | Indent choices (2/3/4/tab) |
| Beautify and minify togetherCSSPortal and CodeBeautify do both in one screen; we split minify onto a separate CSS minifier tool. | Beautify only (separate minifier page) | Beautify only | Beautify + minify | Beautify + minify | Beautify only |
| Open or upload a fileWe support opening a .css file and dragging one onto the editor. | Yes (open .css + drag and drop) | Paste only | Yes (load file) | Yes (file + URL) | Yes (upload file) |
| Copy and download outputCopy-to-clipboard and download are standard across the group. | Yes (both) | Yes (both) | Yes (both) | Yes (both) | Copy (download varies) |
| Live countersWe show live line, character and byte counts as you edit. CSSPortal shows a character count; CodeBeautify shows a line and column readout; the rest show none. | Yes (lines, chars, bytes) | No | Chars only | Line and column readout | No |
| Publish file as a hosted websiteOur real differentiator: after formatting you can publish the CSS file live on Static.app hosting. The pure formatter tools stop at the download button. | Yes (custom domain + free SSL) | No | No | No | No |
| Best forFinal row summarizing each tool's sweet spot. | Formatting then hosting the file live | Deep formatting controls | Power users who want options + minify | All-in-one beautify/minify with URL load | Quick paste-and-beautify with encoding choices |
If you only need to tune indentation to an exact preference, CSSPortal or Beautifier.io give you more control, and both CSSPortal and CodeBeautify bundle minify in the same window. Static.app is the pick when you want to clean up a stylesheet and then put it online, since it is the only one of these that also publishes your CSS file as a live website on a custom domain with free SSL.

What is the best free online CSS formatter, and how does Static.app compare?
The best free CSS formatter depends on what you need. CSSPortal and Beautifier.io are excellent if you want deep control over indentation, sorting, and brace style, and CSSPortal and CodeBeautify both beautify and minify in the same window. Static.app's CSS formatter is the best pick when you also want to do something with the file afterward: it runs entirely in your browser, lets you open or drag in a .css file, shows live line, character, and byte counts, and copies or downloads the result. Its real advantage over pure formatter websites is that it can publish your formatted CSS file as a live hosted website on a custom domain with free SSL.
Is it safe and private to format CSS with an online tool?
With Static.app it is, because the CSS formatter runs entirely in your browser. Your code is processed locally and is never uploaded to or stored on our servers, so nothing leaves your device during formatting. Not every online formatter works this way, some route your code through a server, so if privacy matters, choose a tool that states it processes client-side. If you later choose to publish the file as a hosted website, only then is it uploaded to Static.app for hosting.
How do I format a CSS file and put it online?
Open the CSS file with the Open .css button or drag it onto the editor, then click Format CSS to add clean indentation, line breaks, and spacing. You can copy the result or download it as a .css file. To put it online, use the Host your CSS button to jump to the upload section, where Static.app publishes your file as a live website on a custom domain with free SSL, something a plain formatter tool cannot do.
